[Q] Multiple Bluetooth connections to ICS - Android Q&A, Help & Troubleshooting

Hello,
I am wanting to setup a work station to use my phone as a 'desktop'
I have a mhl to hdmi adaptor ordered, I might have to use the 3pin pogo for power to the phone but I need a keyboard and mouse to connect to my phone.
My question is, does ics 4.0.3 on my Galaxy Nexus support two Bluetooth devices connected at the same time?
Thanks
Dan

[Q] HDMI and wireless mouse and keyboard

Is it possible to connect galaxy s2 and HDTV with hdmi (mhl) adapter and at the same time use the wireless (but not bluetooth) mouse and keyboard connected to galaxy s2?
(i want to use my internet connection on galaxy s2 and browse the web with mouse and keyboard, all that on the TV)
I manage to do this separately, either Full HD via MHL adapter, or using both mouse and keyboard via Micro USB to USB converter and dongle for wireless connection. Dont know how to combine those together though.
I think that bluetooth mouse and keyboard would work, but would like to know about mentioned method.
Maybe self powered USB would help?
thx
Wireless mouse and keyboard will obviously require a USB dongle to receive, so I seriously doubt that you can do this. It's not often that you get a mobile device that is capable of being a USB host, so I find it very doubtful that you could plug multiple USB devices into it at the same time.
I know you said you don't want bluetooth, but I really, REALLY believe that this won't be possible any other way.

[Q] HD dock and mouse/keyboard

Got a quick question for those of you with the HD dock. Are you running dual USB devices for you mouse and keyboard, do wireless usb devices work for the dock sans drivers, or has anyone found a way to pair dual devices to have a bluetooth mouse and keyboard functional?
My dilemma is where I am planning on putting my dock, it's going to be really difficult to use wired devices because the dock is going to be located physically behind me. I need to find a way to go as wireless as possible so but at the store we were only able to pair up one bluetooth device at a time. Has anyone found a work around for that?

I've tried a couple of wireless keyboard/mouse combos plugged into the dock and neither worked. I'm currently using a powered usb hub plugged into the dock with a Logitec keyboard and mouse plugged into the hub. Works great.

Damn... That's what I was afraid of. My issue is I'm placing the dock on my nightstand located next to my bed for charging purposes. What's throwing me off is in one of the videos demoing the dock it shows them using both a wireless keyboard and mouse. It's gotta be possible, but I have no clue how. At the store we couldn't pair up two seperate bluetooth devices at the same time.
May have found a solution to my problem. At a local Compusa I found a bluetooth keyboard and trackpad in one. I'll take it to work and test it out... If it works, I'll report back.
My Logitech Wireless Desktop (USB Unifying receiver) worked fine, out of the box - keyboard and mouse.
There shouldnt be any reason that your generic wireless device/receiver combos dont work since they're simply a transmitter/receiver pair, your problem is likely with the lack of adequate power supplied by the dock. Theres no way that power supply puts out enough to power the phone as well as the USB ports so thats probably why the powered USB hub mentioned above solves everything.

Connect Motorola lapdock keyboard/mouse over bluetooth to a samsung galaxy s2

Hi Guys,
i bought a motorola atrix lapdock and i'm looking for a way to connect this with my samsung galaxy s2. I think, the easy part is the connection via hdmi to the smartphone. The Problem is to connect the keyboard/mouse output over the female micro usb connector with the phone.
Im looking for some kind of 'wireless' solution. There are a lot of bluetooth keyboards (and mouse) devices available on the market, which works with a smartphone.
In my imagination i have a small device which tunnel the keyboard and mouse signal over something like bluetooth to the smartphone.
Did anyone see something like this? Or has someone a another idea, how i can to connect the lapdock mouse/keyboard to the phone.

You can probably look into building your own converter using this:

Haven't seen anyone do it before but I think it's technically possible.
Late to the party, but I think it can be done too. The lapdock keyboard and trackpad are usb hid (someone please correct me if I'm wrong). So, thinking out loud:
Lapdock usb --> usb microcontroller --> bluetooth hid
That's oversimplified, but it's a start. Question is, would such a setup recognize both keyboard and trackpad, or just one of the two?
**edit**
I found a link to a guide using an arduino and a bluesmirf hid. But I can't insert links yet, so if you google "arduino bluetooth hid" one of the results should be a site called kobakant. Very interesting write-up there.

[Q] Questions About MHL Adapter & OTG Cable Working Simultaneously

Hi everyone,
I have an unrooted Samsung Galaxy S3 GT-i9300 on T-Mobile (UK). Running firmware 4.3.
I have an MHL adapter that works perfectly. I also have an OTG cable that also works perfectly.
I wanted to be able to connect my PS3 controller and display the game on my TV, so I bought an adapter from eBay and after plugging it into the phone and connecting the power cable, it simply charged the phone and the phone didn't recognise that the HDMI cable was plugged in or the PS3 controller either. So I got a refund and purchased the official
Samsung Multimedia Smart Dock(also from eBay)which is compatible with the S3 and it was exactly the same result as the cheap adapter I bought. The Smart Dock didn't recognise that the HDMI or the controller, it just charged the phone and nothing else.
Does anyone know why this is happening? For me, it doesn't make sense because the MHL and OTG cable work fine separately with their own individual adapters, so I can't see why they can't be connected simultaneously. Does it have something to do with the 4.3 update?
Can anyone please shed some light on this issue?
Thank in advance

Pair the controller to your phone via SixaxisTool so that it can connect wirelessly, and then connect it (your phone) to your TV via MHL. It works for me.

[solved-ish] Fan firmware screwed up HDMI output?

Hi!
Background:
I'm an esport producer and after some nightmare productions I'm really excited about the rog phone as it seams to be the only phone that have the features needed to make it into a good esports phone (e.g. Having 8-10 players competing in from of an audience), mainly: Hdmi output, ethernet capabilities and usb-c ports on the side..
Problem: After first successfully testing out Hdmi + ethernet connection I wanted to try if I could use the fan accessory and still be able to get the Hdmi signal from it.. When I connected the fan it told me to update the fan firmware so I did, but after that I'm not able to get Hdmi signal either with or without the fan accessory.. For instance, when I plug in my portable asus laptop monitor (power and signal from usb-c) the monitor starts to boot up and then dies.. Then tries again and dies and so on.. On my Samsung s8 it works fine.. So I'm guessing the firmware limits the power that the phone can output on the usb-c port.
Question, has anyone else experienced this issue? Is there a way to uninstall the fan firmware update (that obviously did not only affect the fan but the phone as well). The Hdmi adapter I used was something very similar to the professional dock but is actually an usb-c dock ment for laptops..
Tl:dr; hdmi doesn't work after "fan firmware update", plez halp.

Just a small update,
I was able to get it to work if I disconnect the power cable from the USB-C dongle and then connect it again.. and sometimes it also requires me to disconnect the HDMI + reconnecting that as well.. so I'm not sure if this actually was due to the fan firmware or just a result of a... weird bug(?) when it comes to the OTG features of the phone.. because connecting the dongle with both HDMI + power already plugged in does not work.
Anyway, just wanted you guys to know that it does work, just need to randomly connect/disconnect cables from the dongle first =)
Best regards,
Which USB-C to HDMI adapter were you using? I am looking for one that works with this device, aside from the fairly costly pro dock.
