View Full Version : Bleutooth reception is weak

I experience terrible static sound if I carry the Universal in my leather belt case.

It must be due to the placement of the bleutooth reciever in the device. If I use the headset (I use a Jabra 250) in the car and the Universal is sitting on the chair I have a perfect signal. However, if I put my MDA Pro in the leather case and its hanging on my belt its terrible. As soon as I take it out of the case reception is perfect.

I don't have this experience if I use the headset with my Motorola Razr.

Conclusion: BT reception on the Universal is weak.

Now I have a similar experience, and given that the BT software in XDA's has been fairly crap all along, I wondered if people with updated BT roms or whatever had a better experience.

Anyone with the latest JJ rom able to comment or compare?

I have the last ROM on it, and I don't know if it has the last BT update, but what I can say is that BT signal, using my Bluespoon AX BT headset, is very weak. If I turn around my self...I can loose BT signal...I don't know if it can depend on headset or phone...but really I don't like this!

I mentioned this before, I keep my JJ in its pouch (HP Ipaq 5550 case) on the same side of my body as the ear on which I place my BT headset. I have found with other devices (SE and Nokia) that if the pouch is on the other side to the side you have your BT headset the signal will be much weaker.

I saw your post here. Indeed.......if I put my Universal upside down in the belt case reception is a bit better.
This enforces my opinion. The BT receptor obviously is located in the bottom part of the device:http://forum.xda-developers.com/viewtopic.php?t=26375 This means that if the signal has t travel through the whole device signal is weakened a lot.

Is there a way to boost the signal?

Just do the following test to see what I mean:

Start a telephone link between your universal and your headset.

Now. Turn the universal with the bottom to the headset: Reception is great, even after several meters I experience no static "cracking"

Turn your universal 180 degrees so its facing with the top directly to the BT headset. I experience severe noise even at half a meter........

Please post your findings here. If its just me I have to exchange my device.........

Tnx.

These cases that you mention, are they the bog standard slip-cases that ship with the phones or are they the ones with aluminium in to help protect the device?

I only ask the question because I once tried an aluminium case on my XDA2 and it blocked most of the phone signal.

The advice Jah gave is also contained in most BT manuals, i.e have the device on the same side of your body as your headset.

I get the feeling it's not the case, but the device itself.

Do the table test and report back!

I'm gonna do it after my tea :P

I have the same problem with my device as well.

I also agree it's the device problem and not the case.

I am using a full leather holster case (Nutshell, NZ ), no alu or other metal in it. There is no interference from the case in a BT signal whatsoever. Its the device itself that shields the BT signal.

This is a major design flaw, overlooked by HTC. The sheer bulk of the Universal sits between the headset and the place where it is carried most: The belt or the pocket.

Today is the first time I used my Jabra BT800 and JJ (in the vertical PDAir case) outside. The signal strenght between the BT800 and the JJ was very weak even when I took the JJ out of the case. I had a similar problem with my SE P800 (three years ago). The JJ and BT800 seem to work well when inside a room or in the car.

hi

i'm afraid I have exactly the same issue. have tried with bluespoon ax, Plantronics 640 and Bluetrek G2. All have reception issues.

pity, because this phone REALLY needs a headset.
