BlueTooth reception Sucks....

[smtownsend]

I've used three SX66 vairiants of the Blue Angle and all of them have Crappy Bluetooth reception. You have to have the phone is your shirt pocket on the side where the headset is.

I know its not the headset as we have tried 4 headsets and they all work great with other Bluetooth phones. I can answer my Nokia phone from 2 offices down the hall with my Logitech Traveler. On my SX66 I cant answer it from my Cargo Pants Pocket with out getting masive static.

All the SX66s I've used are the BT v 3900...

Any Suggestions?

I have been up all night searching for an answer to this as I thought it was perhaps a problem related to upgrading. Then I remembered it was doing it before I upgraded. I wonder if it has anything to do with radio version, etc.
I would really, REALLY hate to go back to using the default earplugs that tangle if you think too hard.
Come on guys, is there a BT reception fix I'm overlooking? I was in a conference call yesterday from home and it sounded like someone was balling up candy wrappers in the phone on my end and the other's until I had to disable the headset and continue with the XDA IIs to my ear. :evil:

no bluetooth fix sorry.

radio has nothing to do with bluetooth

I've been looking at this issue as well.

Per the nekkid blue angel pictures from the wiki, the bluetooth antenna looks to be a tiny chip looking thing...

Has anyone considered (or even did) replacing it with something a bit more substantial?

The wifi antenna is kind of small as well. GSM antenna looks OK.

try I Tech Clip II mini.
this is what I have been using for the past 4 months and has been great.
I have tried different types of Jabra BT, Mobile traveller.. none has worked and waste of money.

until i find this one... works great.

Hi Jdc,

I cant find the pic you are talking about, if you could give me a pointer to where the bluetooth antenna is I see if I can come up with anything.

Hi Jdc,

and

I can't find the page that lists which one is which now (naturally once I'm looking for it, it hides), but IIRC the wifi antenna is that small clipish looking thing at D-20, the bluish one at H-20 is the bluetooth, and the big green thing at the top of the board (letters C-K, numbers 1-6) is the GSM antenna.

Looking closer at the board, it would almost appear that there is an external antenna hookup as well for the wifi?

If I didn't have a cracked screen, I'd take mine apart to find out. I'm worried that if I did, the screen would totally stop working. :-(

That seems a bad location for the BT aerial to me with the charge socket at the back and all that shielding above.

I read an article about moding a usb dongle :
http://www.pentest.co.uk/documents/bt_dongle_mod/bt_dongle_mod.html

I’m thinking maybe we could try something similar on the Blue Angel but with an internal aerial in a better location, a bit like these ones on ebay:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=200142840418

what do you all think?

what do you all think?Agreed, it is a bad location. Especially if one considers that often, one holds the unit in hand at that location, covering up the antennas.

Assuming that is the bluetooth antenna (I'm fairly sure it is, considering that is looks similar to the one in the dongle you linked to), I would think that it would be better to use one of those wifi antennas in the ebay link (or something similar) and try to keep everything internal to the phone. Since bluetooth does run on the same frequency as wifi, in theory, it should work.

No one wants to use a phone with a bunch of wires hanging off of it, otherwise why would we be complaining about the bluetooth range? :)

Now, if that other connector looking part is the wifi, the battery normally covers it. Unless there is a way to extend that to another user added jack, the same idea(s) for the bluetooth would apply.

I do not know how tight the clearances are inside the angle, as I've never opened mine. one would think that there might be a way to run the antenna wire on the inside of the back, or along the sides of the plastics. Perhaps around the GSM antenna area? Or would that cause too much interference to the phone/bt/wifi?

Love the read about this, but there was quite a discussion about this problem when the BA was released. I argued it with orange for pretty much the entire length of my contract, it was a faulty bluetooth driver. and surprisingly enough O2 and t-mobile got it right with their XDAIIs and the MDA III firmware's but Orange didn't get it right till almost about a year or more later. needless to say it started working after i pugraded the firmware later on. since then i'm now runnign t-mobiles firmware on it with the o2 active program ( hahaha yea best of both ) and it's been fine for me. So look into upgrading to any of the offical roms from whatever network your looking for, if' you've already unlocked the phone, great as should remain unlocked, if doesn't just re-run the unlocker

Mine is an XDA iis form O2 with the last offical O2 firmware wm2003 1.40.242 WWE on, I`ve also tried T-mobiles 1.42 and upgraded the radio to 1.15 but bluetooth still sucks with a headset!

Maybe you got lucky or maybe its the headset you are using.

Has anyone got an update on this subject since Aug 07?
I have the SX-66 version (Cingular/AT&T)
I have had this phone Since the middle of 2006.
I have upgraded to what I believe is the most up to date programming mods that are available: (other than WM5/6, of which I have planned to do in the near future, I have tons of software and utilities that only run in 2003 edition and I would have to reacquire.)

BA---PH20B1
WM2003 2nd edition
Ver. 1.42.00 WWE
Build date: 09/05/05
Radio Ver.: 1.15.00
Protocol: 1337.45
ExtROM: 1.40.125 WWE
BT- PPC/PE Ver.: 1.0.0.3900

The thing about Modding the chip or placing an antennae jack IS that, all of which that is exposed, in the naked pics of the Blue Angel, are all in fact, canned and can be difficult to expose, to do any modding, without micro precision equipment and a steady hand. I have accomplished modding regular cell phones this way, however, this device is a bit more at risk and can get expensive and messy. I have a few boards, I have acquired through buying spare parts for mine in the case of accidents, of which I have performed with ALL the help of these forums. I will work on this, at this point IF you folks do not have any other alternatives, outside hanging pointless wires hanging around (me thinks that is WHY the bluetooth and wireless technologies were implemented?) With any success, I will report, outside failure, with some sort of procedure and details, that maybe someone with a bit more knowledge and expertise can modify to a possible easier closure on this REAL problem. Sure there are maybe better devices that can, maybe measure up to this Blue Angel, but I love my Angel, even with the flaws!
It has been a great challenge and all of the possibilities that XDA development has brought to the table.
In the last 2 years I have had this phone this is my FIRST posting.
The Bluetooth has been my ONLY real problem. I have to carry it in my shirt pocket using a BT headset and it is still really bad at that. I have used some of the best headsets and gone to great expense, to try and alleviate what I thought, by chance, that I could have finally found one that would superceid
the problem, however, to no avail, I still have the same problem.
If by chance that I could actually find a bigger chip, I think I would have to have the right drivers for it and will have to lead a command string, I am guessing through going to the kitchen and cooking up some ExtROM for the 'moddapplication'? :rolleyes:
Blackberry has, I think, one of the strongest chips available. I have a 7100t that i could answer from 300 ft of a house with walls. My 650 isn't that good.
I apologize for being long winded, I suppose I am catching up from not communicating in the past, but I followed the rules of this site, and I haven't needed to ask a question and not needed to help someone else, because you guys have had the answers in these forums. Without further a'due........


Finally, if you have any FRESH ideas or direction on this bluetooth delima, outside using a can opener, :rolleyes:.........***please***, let me know............

Best regards,
gcopher :D
