Adding DAB functionality - MTCB Hardware Development

Just wondering what the options for adding DAB functionality to an Android head unit are - The FM reception on my unit is very poor.

I've been trying to find info on anyone using a directed HMHD-1000 with an android device/head unit.

Hello.
I work on a Solution for DAB+ in Germany. I have a Calearo 16v DAB+/FM Antenna. So i bought this: http://www.ebay.de/itm/NooElec-NESD...Tuner-Black-/151167807992?hash=item23324db1f8 and put it with Adapter http://www.ebay.de/itm/380790704616?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT at my DAB+ Antenna.
Apps i use for this:
- Wavesink Plus DAB+ FM-RDS
- RTL2832U driver
with my Phone it works awesome and its a really cheap Solution. I'll try it tomorrow in my Car.

I have a monkey board with an app for android (https://play.google.com/store/apps/details?id=wal.dabmonkeypro) and that works great

Hey Folks.
My Solution for DAB+ with my Joying Stereo works very well. It should work with any other Android 4 Car Stereo.
What you need - Hardware:
- Nooelec Nano Stick with RTL2832U + R820T Tuner
- in my Case a Adapter for my Calearo 16v DAB/FM Antenna - a SMB/MCX Adapter
Software:
- RTL2832U Driver Playstore
- Wavesink Free for DAB only MP2 Files (Playstore) or Wavesink Plus for DAB+ and Recording (Playstore)
How to:
Connect the Antenna with the Adapter and the nooelec USB Stick. Put the USB Stick in the USB Port of the Radio. Install the Software. Start Wavesink and search for Channels.
Enjoy DAB+ in you Car Stereo.

Thanks for posting your solution.
Where did you mount the aerial?

Hey Dogballs its a Roof Antenna. I bought this 1 1/2 years ago. Its a great Antenna. http://www.calearo.com/eng/automoti...tennas/16v-combi-am-fmdab-dab--pno7677932.php

Cool, thanks.
The only thing I can find close is this..
http://www.ebay.co.uk/itm/Mini-USB-...e-MCX-Input-/201349905111?hash=item2ee163bad7
Do you think this would work with the driver you mentioned? the description says its for windows.
I just dont want to order the Nooelec as it is in the states, and could take weeks to arrive, by which time i'll have lost interest in this project..

Looks good to me. Chips are the same, and the Design looks even.

Excellent, and finally... This plugged into the same usb port where you would plug in your usb hard drive?
Thanks for this information.

Yeah. Just one of the USB Ports. Which One doesn't matter.

I just need to find a decent internal DAB antenna now as the one which came with USB adaptor was very weak, even on the roof.
I had to drive to the top of a hill to get a decent reception..
Thanks again..:good:

You're Welcome. I have this Antenna. The great Signal is worth the Installation Work. : http://www.calearo.com/eng/automoti...tennas/16v-combi-am-fmdab-dab--pno7677932.php
the Installation is in fact really easy. Loose the Screws from the Headlining (German: Dachhimmel ) loose the Old Antenna tie the old Anntena Cable and the new Antenna Cable together and pull the Cable with care to the a Pillar. Fix the Screw from the new Antenna and fix the Cable at the a Pillar behind the Dashboard to the Radio. You need a good Hour or 1 1/2 Hour. Excuse my imaginatively English

Hi Michael,
thanks for this good information!!
Two questions:
1. do I need root?
2. did you check DVB-T as well? (the stick can DAB & DVB-T)
Thanks

Based on your video it looks like you've got an e46, I'll be picking one up soon so if you come up with a good antenna solution let me know!

I have root through a custom Rom. If you have a stock Rom with Android 4.4 go to factorysettings press *#hct#root# and you got temp root, install superSU and you got Perm root.
I didn't check DVB-T. In Thuringia are only a few Channels from ARD/ZDF. I don't need them in my Car.

I tried allready with the code, but can't install superSU or SU?
Nevertheless I ordered the stick and will give it a try.

With my Joying Rk3188 1024x600 Android 4.4 Stock Rom the Code worked perfect. But it should work without root.

Yeah mate, E46 here..
Still working on the antenna, not so easy with these being built into the rear window.

So got my DAB USB today, but only get 3 stations (the strongest in my region).
Could it be because of the crappy antenna?

a bluetooth to 3.5mm dongle?

ok im running 5.0.2H and it has stereo bluetooth right? have to make sure of that first lol.
In my car I dont have bluetooth, I just have the standard AUX input. So I was thinking of buying some type of adapter to plug into my AUX plug on my cars headunit that can then connect via bluetooth to my G1 to play stereo music.
Can someone recommend some good devices that would help me get this done? Thanks
didn't your G1 come with a headset??? if so you can plug any normal 3.5mm plug into it and it should work fine foger the dongle thing. personally mt G1 camr with a two piece headset, one that plugged into the phone and allowed a 3.5 mm headset plug, and the earbuds that plugged into the first piece. just get a male/male 3.5mm jack and plug it into the first piece, it should work fine
yes I know I can plug a stereo aux cable into my g1 with the dongle but I dont want to. i want to connect wirelessly via stereo bluetooth
any help please?
I've got a friend who uses this dongle with his car sound system and it seems to do the job pretty well: http://www.porta-charge.co.uk/accessory_0283.html
Also try searching google for '3.5mm bluetooth adapter' and a few show up with some reviews.
EDIT: Actually I think that device I linked to is a transmitter that plugs into his iPod and transmits to his bluetooth stereo. Try googling for '3.5mm bluetooth receiver', seems there's a couple of devices that will do that for you, they seem pricey though.
Something like this, perhaps? http://www.gadgetworld.co.uk/p/Mavizen_BluDock_Bluetooth_Receiver.htm
I'm gonna get this but it the website has really slow shipping times since it's from Hong Kong...
i have this just came in today haven't had a chance to use it yet but its smallish and has decent reviews from most places
http://www.amazon.com/Motorola-s705..._1_1?ie=UTF8&s=wireless&qid=1239929599&sr=1-1
yeah godsfilth I was looking at that. can you please tell me how well it works with the G1? I was thinkign of that.

Looks good and a good price too. Pleast post how well it works when you get a chance. Are you running Haykuro?
Im interested in that too.. anyone confirm working?
So considering that godsfilth never posted his evaluation of the Motorola s705 I thought that I would. I figured the specs and price was good, it's still available for $30 from Amazon. Long story short, it works like a charm. For reference I'm now running Dudes .92 with the new radio.
The music streaming connected right away from the default media player. Play, pause, and track changes worked fine. If you hold the "phone" button it will do the voice dialing. I've always found it a bit flaky myself but that's android not the blue tooth adapter.
Once connected it basically acts as the mic and speaker for the phone. The only drawback is that the track controls on the device only work with the default media player. I use mixzing a lot, and the audio comes through fine but if i try to use the controls on the adapter it also launches the default player. I think this might be on the android side though.
Overall, it's well worth the $30.

(mentioned earlier by amgupt01) from DealExtreme for $13. Works like a charm - PlugnPlay. Never again wired headset!
Shipped in 9 days to Sweden (from HK) - actually it arrived to Sweden after 5 days - then the Swedish Postal Service went on vacation, obviously - Not bad, considering shipping is free from DealExtreme.

I just got the s705 in the mail today. The FM receiver works just fine but the BT is a little weird. Like benmyers2941 said, only the default music player will respond to the input from the headset. But when music is playing, every now and then, the playback would pause, then immediately resume at random times. I don't have a clue why. Could the device be faulty, is it my G1, or my FW. I'm running JF's 1.5.
Edit:
I think I have figured out why it was showing these symptoms. I did a wipe and switched to Haykuro's latest and the symptoms went away. After the wipe I realized that I was also running Open Overclock beforehand. If someone could try to use this device while running Open Overclock and confirm/deny that the symptoms are present, then that would point out whether it was the FW or Open Overclock.
Nope. I don't think it's Open OverClock. I think that the device is defective. It will only do that "pause and resume" thing when I'm walking. For what ever reason I can't fathom, it worked perfectly after i made the wipe yesterday. But today, it doesn't work properly. I even put both the phone and s705 in the same pocket. I've tried restarting both while on a walk, but that didn't help. Also, I've had regular conversations on my BT125 with no problem, the same with the default earbuds the phone came with. Does anyone know how I can determine which has the defect?
Well, the usual way - Try the s705 with another phone and/or try your G1 with some other A2DP headset. Can't see any other way to find who to blame.

Hey,
Just a thanks to you guys for the headsup about the $13 bluetooth thingy from dealextreme, just got mine yesterday.
When I heard that the G1 had no 3.5mm jack I was really dissapointed.
As gadgeteer and an audiophile, I was keen to try bluetooth stereo out, but to be honest I wasn't really expecting much (I mean, the G1 doesn't even have a equalizer!)
How wrong was I! Sound quality is excellent, I truely am shocked! I could quite happily replace my Sony mp3 player with the G1 and stereo bluetooth.
This little bluetooth jack will keep me happy until the market in bluetooth headphones explodes after Apple enters the fray.
One comment though, sometimes I can hear the pitch of the audio speedup or slowdown.. not sure if this is the receiver or the phone, not too fussed about it though.
Oh, and having no wires running around your body totally rocks!
Yeah, after a few weeks, I'm still very satisfied. With my use (biking to and fro work) it lasts > one week between charges. Haven't noticed any pitch drift - but then all I listen to is .977 The 80s Channel using StreamFurious. Beats the hell out of any OTA radio station where I live!
One thing - Without using too great force, I managed to pry away the clip - and the spring just vanished into thin air! The clip was easy to put back, but now it's just dangling there. So be carfeul when "operating" the clip.

fm transmitter?

can anyone recommend a quality fm transmitter? dont have an aux input in my car radio (damn thing has everything else but no input!).
I believe belkin might make a mini usb transmitter. But u can use on of those tape deck converters with a headphone attached. That's what I use from time to time. I'm not sure if ur radio has a tape deck lol considering its dead tech lmao
lol! My radio's not that old. Couple of years but was one of the better pioneers. Quite a few bells & whistles, sat. radio, ect., just no stupid aux input!
this one is £4.99 ($8.15656) it is really good once you find a free frequency and powering it from the car cigarette lighter is a must because it is SH*T when running it from batteries
Are you sure it doesn't have an aux round the back?
I picked up an FM transmitter from Netto for £1.99 or £2.99 a while back, quite big though. They were selling it as "Wireless headphones" as it came with some FM headphones.

In Italy is not possible to use it as described. The problem? No free fm freqeuncy, and even if found one in the car is mandatory to change frequency to find new frenquently. So useless, the only solution can be to remove the camble of the antenna and to put it near the fm trasmitter but in this case we have to rennunce to the fm radio.

Same for me. I have the Belkin transmitter, but never could use it.
You just struggle to find a free frequency, and a few kilometers later, it is all jammed already.
I even tried to find something like 3 different frequencies for different parts of my daily trip... and I failed...
And even when I found some working frequencies, sound was rarely free from perturbations.
Note that country legislations are different (I am in France) and maybe in us you can have a transmitter with stronger emission, which might improve the situation a bit.
( linked Belkin product : "This product is compliant with the EU standard for Band II Low Power Devices for use in Germany, Switzerland and Iceland" so maybe try a US version instead ? )
I did not try unplugging external antenna. If it did solve the problem, you would have to find a way to have a switch to plug/unplug it... (not so easy !)

for me the only solution that can let it work properly is to find the cable of the antenna in the car. After discovered out where is located try to put the trasmitter very close to the antenna cable. It can work. Another solution can be to reduce a little the power of receiving signals of the antenna, that can let to listen good the frequency well trasmitted and at the same time to
free some others.
Found this on Cellphoneshop.com
http://www.cellphoneshop.net/dashfm.html
Dude fmtalk kicks ass!!
update: I tryed to use the fm trasmitter buyed without the battery but only using the alimentation from the car. The things seems to work really good now. Even with a not clear radio station is trasmitting with more power and the signal of the fmtrasmitter is going over other signals.
If is possible to reduce a little the power of the car's antenna it will be really really perfect!
Here is one from Dealextreme.com.
Pros:
Cheap
Puts out a strong FM signal
Remote is nice, even though it's goofy looking
Charges and transmits at same time.
Cons:
Low Volume
Bad bass output
Takes forever to arrive.
Cheap plastic.

Yep, just got mine today as well. Works fine, remote is goofy as hell (have yet to try it though). It could fit a little snugger, but it holds will concidering the extra thickness with my battery.
No weird hissing and strong output with pandora and music on my sd card.
4/5 for it "just working", but doing it well.

g9 fallen on the floor, wifi signinal is almost dead

hi, my child has made to fall my tablet (101 g9, 8gb, with [email protected] v03) on the floor. tablet has opened some millimeter in an angle, I have closed again it, and the tablet seemed to work. but now the wifi signal is very very low. I must put it to few centimeters from the router to have a very low connection. I have opened the tablet and everything seems to be ok. where is tablet antenna inside? is it possible that is detached? it is a sin since the tablet was enough stable and with directory bind I have moved all games/gps datas on sd to have free space on internal memory... thank you and sorry for my poor english. ciao

Hi, before you do anything else, I would check on ARCHOS website to see if RMA will replace your device, that would be the best way to do it.

If you are not successful with a RMA from Archos, you may be able to repair it. When I opened my G80 I noticed 2 thin metal strips with wires soldered to them. One should be an antenna for wifi, the other bluetooth. You may have just broke the wire connection to the antenna strip. Don't open it until you talk to the manufacturer.
There are two wires coming from the corner below the HDMI socket. The black one is the GPS antenna and the white one is the WiFi. Just follow it round to the antenna. Check the cable hasn't become disconnected at either end.
solved! thank you! in my case, I think it was bad assembly of the tabled, my wifi cable was placed over on pin of the tabled body that with time, it has cut the cable internally. some pictures to clarify (original photo by "scholbert"), the wifi cable is white. "my table" photo is scholbert's photo edited with ms paint. thank you and sorry for my poor english. ciao

I noticed that mine had been trapped and wonder if this is part of the problem with the GPS not working properly.
I have tried to re-route the wires but they simply don't have enough length to go a better way.

No re-route used - just put back together carefully.
I also followed the steps given by scholbert which are :-
#######################
Anyway some hints of what i found out while fiddling around with the GPS:
- disable Automatic date&time in the date&time settings
- disable Google's location service in the Location service settings
- enable GPS sattelites in the Location service settings
- if you use GPS status from EclipSim:
- in the tools delete AGPS data
- in the settings disable Auto-download of AGPS data (set to never)
- reboot
- start GPS status & wait
Have fun!

I left it on the window sill for about 3 hours after doing the above
I have also downloaded MapFactor Navigator which is running smoothly at the moment. It's on the market.
I am still getting satellite fixes OK - inside, a couple of meters from a double glazed window.
With Navigator is also relatively easy to install your own POIs so all is good at the moment
I am feeling more confident in it's use as a navigation tool.
I am still contemplating buying a bluetooth GPS receiver just to use as a backup if need be though !!
Bluetooth GPS
I have got a GlobalSat BT359 Bluetooth GPS receiver off eBay for £11 (sold by sat_nav_accessories).
Downloaded Bluetooth GPS (Googoo Android)
Paired my Archos 80 G9 with it.
Now I have excellent GPS fix - EVERY time, in SECONDS.
I downloaded and am running free MapFactor Navigator (Mapfactor).
Free opensource maps for virtually anywhere.
And able to easily display thousands of personal POIs with ease.
Just what I have been looking for to find all of those camper van spots all over Europe.
That setup above never worked for me. I will have to try the Bluetooth approach.

[Q] Speaker problems, software or hardware?

My Atrix worked flawlessly for the last 6 months on Jokersax's ICS rom and CM9. Last month my headphones stopped working, and a work or so ago speakerphone stopped working. 2 days ago the ear speaker went out. The mic is still working fine, I just get no audio whatsoever.
Any ideas?
It's at a repair shop at the moment, but the guy called and said he's not seeing any issues with the speaker itself.
If it is software, what might fix this? I even tried flashing a new rom with no fix.
My first question is does the headphone out work? I would guess that if the headphone jack audio is fine then you might need to replace or repair the jack on the phone. There is a switch built into it that cuts sound to the speakers when headphones are plugged in. It is unlikely for that to stick, but not impossible. Fortunately. That repair is very easy to do. I have pics of it somewhere. I'll put them online if you need them.
If it isn't that and you can't find audio at the headphone contact points on the board you probably are going to need a new board.

My first question is does the headphone out work? I would guess that if the headphone jack audio is fine then you might need to replace or repair the jack on the phone.

Headphone was the first thing to stop working.
My ear speaker also stopped working. I tried flashing different roms but apparently the problem won't solve. My first guess is this is a hardware issue. Try do the same as in order to make sure.
This is exactly what happened to me. All of my audio outputs were shot. But if I whacked my phone against my hand, sometimes the headphones would work, so I'm betting on hardware. I have tried multiple roms but none seem to work. You can try flashing a GB rom, like Neutrino, with a full wipe, just to make sure its not software. GB roms have all of the official drivers needed for this phone, so they would be the roms that most likely fix it, if it is software.
PS: JdgM3NT4L if you could please put those pics of the headphone switch on here or direct me to them, I'd appreciate it. I'd like to see if that makes a difference on my Atrix. Thank You

You know what, I am so sorry that I let this slip. Here are the photos and an observation.
First pic shows the headphone jack from inside of the phone.
I simply removed the battery cover, removed 8 screws and gently pried the back off.

This photo shows me beginning to remove one of the contacts.
This one shows one of the contacts removed.
And this one shows the camera board where the headphone jack makes contact.
And if you want to simply replace the whole jack it comes out easily, those are available on ebay.
If I was not able to repair your problem by taking those pins out and checking them for breaks, and possibly re-bending them back into shape.
I think that I would consider either a new jack. Or a new camera board, since that is the first point of contact. Also that is where I would check for audio. It would be a little difficult getting the battery in place and manipulating the phone to play while it is apart, but doable with enough resolve.
Please accept my apologies for not responding sooner. I really meant to get to this way before now...

USB-C to 3.5 mm adapter - HTC U11 says "not supported"

Hi I found a pair of USB type C to 3.5 mm headphone jack adapters on amazon, and i plug it into the HTC U11 and before i even plug the headphones in it says this accessory is not supported.
I have headphones all over the place and I want a few adapters to leave on them so I don't have to carry one around with me.
Does anyone know of an adapter that is supported by the U11? Or a way to make the ones I have now work?

It's not working because there is no Amp/DAC in it.
Just the original HTC will work.
Unsure what you're asking me.
HTC only sent one pair, where can I get more that will work as I said I have multiple headphones

In Europe they are available on the HTC webshop.
Why you just unplug each time you want to swap?

Buy a few extra OEM adapters. Can't make 3rd party ones work.

Just because I have a pair of headphones in my truck, gym bag, at my office and at home. The ones online are cheap I thought for a few bucks I could have adapted all my headphones instead of having to carry one around!
Those cheap ones won't do. Buy them officially from HTC. Send the Amazon ones back for a refund.
Any idea on what options you have for spares in countries HTC does not not offer the adapter for sale (Australia for example)
Anyone want to trade their adapter for my headphones? I have never liked the earbud style I cannot get them to stay in my ears I would rather use the over ear headphones I already have but want more adapters
Adapter cost 13e and shipping 26e Wtf htc
HTC won't ship from UK store to US.... US is sold out. This sucks

I recommend the Griffin iTrip. Its a Bluetooth receiver and easy to setup. Sound quality is good. Its cheap as well. https://griffintechnology.com/intl/itrip-clip-bluetooth-headphone-adapter
Guys, install app SoundAbout.
Works fine for me with generic USB-C Adapters.

So with this app it works with usb c generic audio adapters? Is that a paid feature or did it just work by default? Thanks!

Yes! Works fine with cheap USB-C to 3.5mm adapter. I use it on my U Ultra, that come with no adapter in package.
I bought the Pro key, that´s enable other type of output. Is this case. just select "Wired headset with Mic"

Do you know how this works. Is SoundAbout a DAC what exactly is it? I am asking because I got the Pixel 2 and it does not have a analog out like The HTC Bolt or HTC U11

It works. I can only suppose how it do it. Routing outputs. As U Ultra and U11 have analog output over USB-C, it route output to USB-C pins and you will have an analog output with analog quality. The DAC will works on board. I can say that quality differences between original HTC adapter with DAC and a generic with soundabout are minimal.
That´s it. It Work.
I bought this because I had an U Ultra before and it come with no HTC adapter and I love my 3.5mm phones.

Oh so then the U11 is different then the Pixel 2 then as it puts out digital out on USB-C only.

Maybe Pixel 2 doesn´t have analog output over USB-C or it´s blocked. Think that if you have speakers, you have an DAC onboard to convert digital to that analog speakers.
Have you tested SoundAbout and nothing happens? Even routing to different options? Or another adapter? on U11 an U Ultra I´ve tested on many types of adapters, including original Moto Z and all works fine.
But I don ´t have a Pixel 2 to test. (HTC and Pixels are rare on Brazil)
