Hi everyone,
I am an owner of the GSIII I747M and the ASUS Transformer, both running ICS. I recently had this idea (fantasy?) where I mount the Transformer in my car, hook it up to the car speakers and basically use it as my in-car infotainment system instead of the headunit that's in there. Nothing wrong with my in-car headunit (except the fact that I can't get bluetooth to work with my GSIII), but the tablet will give me tons more features. When I enter the car, I want the tablet to automatically tether to my phone via wi-fi and via bluetooth. Wi-fi is for internet access and it works just fine. The bluetooth is for the hands-free profile, so that when I receive a call, the music/navigation/whatever gets interrupted and I can take the call. I also want to be able to dial from the tablet.
When I connect the two devices via bluetooth, I don't have a hands-free profile; indeed I have no useful profiles at all. My question is simple: is there an app for that? Any suggestions? Has anyone done this? Thanks!
Does anyone have the same issue where the wifi becomes wonky when the bluetooth is on and connected to a bluetooth keyboard.
I have the Sony Xperia Tablet Z wifi version with an Apple bluetooth Keyboard.

It's a common problem. Reported all over another forum.

I am having the same issue using either a Bluetooth keyboard, mouse or sixaxis controller un my Tablet Z Wifi.
If someone is using a bluetooth keyboard/mouse without wifi problems, could they post here as well. I would like to know If every one has this issue.
This thread is about the same problem: http://forum.xda-developers.com/showthread.php?t=2346553 could the be merged?
I'm listening to internet radio over bluetooth (instead of the inbuilt speakers), have a Microsoft Wedge Bluetooth keyboard connected and am writing this at the same time.
2 Bluetooth devices at the same time plus Wifi, all working.
(Wifi channel is 9. SGP311.)

@hasenbein1966 Could you do a internet Speedtest with and without bluetooth connected, what firmware are you running, and how many wifi networks are on your channel?
My Internet is fast (30000kbps download) I am geting that speed on my tablet z. As soon as I connect my bluetooth keyboard (acctully it is the Microsoft Wedge as well) it drops to ~300kbps. So something happens to my wlan on the Tablet Z. As I am living in a Flat I do not have a channel for my self. I am sharing that channel with 2 other Wifi Networks.
If someone knows what to change on the Tablet Z please tell my, I bougth it just for working with keyboard/mouse!
Mine is SGP312 (32GB, Wifi only), firmware is 10.1.C.0.370, device is rooted, bootloader is locked

just tried playing around with my channels...
the good news is i think i may have actually upped my speeds by changing to a different channel!
the bad news is i drop from around 3.5MB/sec with just wifi on, to under 0.03MB/sec with Bluetooth turned on and a bluetooth keyboard connected... and then it didn't even finish the speed test, it just stopped and said there was a connection error.
this is awful.
Did someone already test whether changing the WiFi to a 5 GHz channel (Bluetooth works in the 2.4 GHz band where also normally the WiFi operates) helps?
(Can't test it myself because my router doesn't support 5 GHz.)
Hi All,
This seems to be pretty common (saw someone complaining in the Transformer forums). I've noticed the same issue myself. I'm using wireless BT headphones, and the Wifi throughput drops precipitously when I'm streaming music to them. I've got a dual-band router, so I'll set up the tablet to connect to 5Ghz and let y'all know what happens.
Thanks,
John Francis
I have now measured speeds with a speedtest app.
When I only have connected my Harman Kardon Bluetooth audio receiver, the WiFi works perfectly normal and has same throughput as without Bluetooth on.
When I connect my BT keyboard, Wifi speed becomes very low (below 1 Mbit).
So, not BT in general is the culprit - it depends on the kind of device!
OK, with the tablet on 5GHz I get ~55 Mbps. On 2.4 GHz, ~21Mbps. These are Harman Kardon BT headphones.

John Francis

@jfrancis999 these rates look both ok. There shoul be no problems. Are these with audio streaming to the Headphones? If you have a Bluetooth keyboard, mouse or gamepad (playstation 3 controller) could you maybe test with one of these connected an 5GHz?
@all if we make a list of all working and not working devices we can maybe find what they have in common an what is the problem.
Not Woking:
Microsoft Wedge Mobile Keyboard, BT Profile HID, BT Version and Class unkown
Playstation 3 dualshock3 controller, BT Profile HID, BT Version and Class unkown
Whit these devices connected Wifi speed drops to under 1Mbit/s
Does any one have a BT Keyboard and while it is connected to the tablet z Wifi speed does not drop under 1Mbit/s?
@someone having good understanding of android and bluetooth: is there a way, I can force the tablet to reduce trassmitting power to class 2 or 3? I want to test if that makes any difference but I do not know how.
It's really strange, since a simple keyboard should need much less bandwidth than transmitting audio over BT, so one would expect the Wifi drop with the audio device, not with the keyboard...
I just have a Motorola Keyboard & Mouse combo pack... I'm not seeing any model number on it, but it's definitely Motorola. Totally kills wifi speed when either one or both are connected. So you can add that to the list.
Hi All,
With the tablet connected to 5GHz I get the following speeds:
* Playstation 3 controller disconnected: 58Mbps down/30Mbps up
* Playstation 3 controller connected: 42Mbps down/12Mbps up
With the tablet connected to 2.4GHz I get the following speeds:
* Playstation 3 controller disconnected: 4Mbps down/30Mbps up (not sure what's up with the download speed)
* Playstation 3 controller connected: 103Kbps down/52Kbps up (OUCH!)

John Francis
@jfrancis999 Thanks for your tests!
I will be in my office on Monday. There I will try a 5GHz wifi as well. If that works well, we have at least a workaround. Still, I hope there is a fix for this problem, but untill then we could bypass that problem.
I will post the results here on monday.
I am still looking for someone who can tell me, how to reduce the transmission power of bluetooth on android!?
after a week, sony support finally wrote me back. they said it sounds like a software problem and i should use the PC Companion software to do a software repair. anyone else tried this yet? also if i do this, is there any way to backup EVERYTHING, including my widget setup, icon placement, folders, settings... all of it...
Bah, they simply have no clue.
Like the dudes on the official Sony support forum, this support guy just gave some random halfway "fitting sounding" answer, like a Windows support guy who says: "Restart Windows"...
I wouldn`t use this "PC Companion" crap, honestly.
Hello,
I have a NEO N003 with Android 4.2.1.
I have to use a Wireless Display and Bluetooth connection at the same time.
But when a activate wireless display in system settings, the system says "Bluetooth will be turned off when you turn on wireless display".
Is there any solution for that?
Thanks and best regards,
Danta.
Hi Danta,
Same problem here, so I'll start following this thread, although not many reactions yet.
Trying to get a Pioneer Appradio running with my non-MHL 4.2.1: HDMI via Wifi, but for controlling my phone from the radio, it'll need BY on as well…
Hope someone will drop in here.

Hi everyone,
I noticed that every time I begin to play music via Bluetooth speakers within 2 mins my wifi internet drops. I remain connected to the Wi-Fi but it shows no internet connectivity. Once I disconnect from the Bluetooth device and restart the wifi on the phone, it comes back to normal and works flawless. My wifi runs on 2.4ghz. I tried changing router channels but there was not much improvement. Is this a fault of the device or is anyone else facing similar issues. If someone can suggest a fix for this it'd be great.
Thanks.
Anyone!!
Hi. I have similar problem. I am using Pebble smartwatch, Mi Band, bluetooth headset, and laso radio in a car, so i have bluetooth always on. Lately i am experiencing massive problems with wifi 2,4 GHz(slow speeds, instability, dropping connection) - 5 GHz is working fine. Yesterday i have read some tips to turn off bluetooth, and EUREKA, wifi 2,4 GHz works fine.... I know that bt, and wifi 2,4 working on similar frequency, but hey, i didn't have those problems with previous Samsungs(S2,S4,N4,S7), so something have to be not ok with my S9+. I've recorded this behaviour https://www.youtube.com/watch?v=VJTPn_GjJs0 . Have you found a solution? I am gathering data for phone service under warranty.
