Bluetooth Streaming Audio with the x50v

havrek · 11-05-04, 11:46 PM

Has anyone tried to stream audio via bluetooth with the x50v? I see several sets of BT headphones out there and it appears that you can do this with the HP devices. Just wondering if anyone has tried this yet?

you mean use a bluetooth headset to listen to the music, or stream music from your pc to axim??

I mean listening to music from the x50v via bluetooth to a bluetooth headphone.

i dont know if it works and it depends on the model

i would wait for someone to try it out

it really depends on the headphone model most of the time :)

I have the verzion motorola v710, and the motorola hs820 bt headset. And yes, they all work together AT THE SAME TIME. Meaning, I can go online using my phone thru bt, AND listening to music on my bt headset at the same time. One good example is, I can logon to an internet radio station using my phone, and listen to the program wirelessly thru my bt headset. this is so cool.

can you post instructions as to how to set this up and use it?

is it possible to stream music from your pc to your axim via bluetooth?

I've had success connecting a BT headset to my Axim and using that to listen to music off the Axim. The sound quality is horrendous though. This was using a Jabra BT250v which is designed for phone use so it may not have been the optimal headset to test for listening.

Using my PC as speakers for the Axim didn't yield better results. I was able to get my PC to act as an audio gateway for the X50v where the sounds from the PDA were sent to the PC and its speakers. The sound quality is just as bad this way as w/ the BT headset. Both sound like something I'd expect from AM radio reception. On the PC, I also noticed the music kept skipping every now and then.

Most likely, Bluetooth is just too bandwidth limited to provide decent quality audio streaming.

It most certainly does work, and not necessarily using headset BT profile, which is intended for talking on phones and the like, is not stereo, and is low audio quality, around telephone grade.

Instead, you use the "high quality headphone profile", or A2DP. This is not supported on the widcomm BT stack (default in Axim) automatically. You need to do some work. See this thread:

Getting BT to work without skipping

The key ingredients (for me) were:
1. Installing the PDA2K_BroadcomCorp_BTUpd.cab. See the above thread for the link to this file. Make sure you install it with BT disabled--see the thread on this. And make sure all your previous BT settings are cleared out first.

2. If you get skipping (I did), use Pocket HackMaster to throttle your CPU down. The above thread mentions using hackmaster CPU config "208/104/52/52...", but I've found that the CPU speed (208, here) seems irrelevant. It seems to be the RAM setting (52) that is magic. I run mine (when listening to music) at 416/104/52/52..., and I get no skips.

The above works (for me) with my motorola ht820 headphones for music MP3 tracks recorded at 128KBS. It did NOT work for some 92KBS tracks I had--the headset would actually shut itself down when the tracks started! I guess the quality was too low for the headset to tolerate. :-) It took me a long time to trace this problem to the audio file format and not a driver issue.

On the other hand, to watch movies (I encode DVDs to Ogg Vobis format 512MB files using FairUse Wizard [free!] and run them from my SD card) and listen to them on the moto headphones, I have to run the axim at full speed, and use BetaPlayer with the audio quality set to "medium". This avoids skips for some reason, still sounds great, and the video runs at full speed with no hesitations.

Hope the above helps,

When streaming music from the internet using your phone to your Axim do you guys have problems of the Bluetooth disconnecting after 10 mins? I have a motorola v360 and it seems pretty consistent. I can stream for 10 mins and then it cuts off.

I have the same problem, but with the OMIZ headphones. I thought it was unique to OMIZ (others have reported the same problem) but now it seems like it may be more of a generic problem.

At the moment I'm not sure if it's the phone or the PDA. I'm streaming music through TCMP at the moment but for troubleshooting I'm gonna try streaming through media player to see if i get disconnected again.

BiGGieStuFF · 01-31-06, 08:42 AM

UPdate: Streaming through Media Player just fine for 12 mins now. It does have to reconnect to the phone for buffering cuz the audio skips everynow and then but it stays connected where the TCMP seems to disconnect exactly after 10 mins. Application issue?

just check my sig
no more asking

I don't think you can do this with the X51v though, since it comes with the MS BT stack, which is severely crippled and only allows for basically DUN and limited OBEX file transfer.
