Sony Ericsson T616 Bluetooth Sound Quality

I have the T616 with Cingular and have had great results with it. I have had some issues talking to my son when he is on his cell with his Jabra headset but I think those problems are with him since I also have problems hearing him on the house phone when he is on his cell. I did have some problems talking to my daughter when she was on her cell (AT&T) and we were driving from Philadelphia to Baltimore. I think those problems were just signal strength added to both on cells. For everyday useage it has been fine.

 

some of the choppyness is due to the bluetooth technology. The system is consantly change frequencies and the idea is that if there is interferance on a wavelenght that it won't be enough to cause any problems in the overall connection. however this being said I've had the same problem w/ my jabra earpiece. It might be that there is interferance on many of the wavelenghts you are currently using. I find the choppyness is not a constant problem and turning the system off and on again clears the connection.

 

I'd still love to know how to switch an on-going call from the Prius handsfree back to the handset on a T616. The phone will not allow an active BT connection to be disabled. The user's manual says there's a menu function to do this where you usually see the 'more' button, but the only option I see is to 'end call'.

 

your right it should affect both directions. the problem i'm having with my earpiece fits this. It seems that this is not the case with the prius connection.

 

A quick answer on the transfering of a call in progress from the Prius to the phone itself:

During the call, press in the "joystick" on the T616 (or T610). This will provide a menu of options, one option is "Transfer Sound". Pressing in the "joystick" again will select the option, providing you with a list of objects to transfer the sound to.

Select the "To Phone" option, and viola, sound is transferred from the Prius to the phone, both speaking and listening. The Prius will remain in call mode (radio muted, etc), but you will be talking through your handset.

Feel free to let me know if you need a better explanation.

I've got a T616 with Cingular and have experienced very good sound quality at both ends of the conversation. I've got firmware release R1B027 which provides the above noted Bluetooth improvements (among other things). There may be newer releases, but this one seems to work fine with my Prius.

You can check the T616 firmware version as follows:

Go to StandBy screen (first screen)
JoyStick Right
Press * (asterisk)
JoyStick Left
JoyStick Left
Press * (asterisk)
JoyStick Left
Press * (asterisk)
Service Info.
SW Information

 

Could you check that sequence please? Doesn't work for me. After 1st asterisk, I'm at Connect. Can't use joystick from there.

 

The sequence works for my phone. I should have been clearer about what you will see (or not see) on the display. When you reach the Connect screen the joystick/asterisk combinations do not result in changes to the screen until you press the final asterisk. Only then does it change to the Service screen where you can select Service Info. Hope that helps.

 

It worked for me.

 

Thanks for the key combo to get into the Service menu. I didn't even know that was there! Checked my T616 version and it appears (according to the Howard's Forum thread) that I have the latest and greatest. (R1B027 prgCXC11-22569.MARTHA, R1B027 prgCXC11-22579.TAE).

There are still issues with the BT connection. I used it a great deal over the weekend, and I can definitely say that talking to an Incoming Call will occasionally drop the call for no apparent reason. If I'm talking on an Outgoing Call initiated from the Prius controls, it has never once dropped on its own.

 

I got the flash upgrade and my T616 works like a charm. Its clear and I set it up to automatic connect to my prius once I turn on the bluetooth setting in my phone. Everything works great.

 

I am buying a used, unlocked, Sony Ericsson T610 which has the firmware upgrade R1B027 inside. Is this the same as a flash upgrade? Im hoping that that this will work with T-Mobil and prius ok.

Awaiting pkg #9 to arrive in 3 wks.

 

It won't work for me either. As soon as I hit the right joystick, I'm in the screen with the various icons for the phone's features. Hitting asterisk takes me to the Connect menu. I'm not sure what's going on.

 

After you start the steps beginning from the Standby screen (first screen), you should ignore the displays until you see the Service screen. Some of the sequences (e.g. JoyStick Left, JoyStick Left, * (asterisk), JoyStick Left) do not result in changes to the display screen. This is really a hidden back door for service technicians. You may just want to ask your local service provider to check your phone to see if a firmware upgrade is available.

 

That sequence worked for my AT&T T616. I have the older R1A version. I also experience poor sound quality out of the car's speakers, although callers say they can hear me just fine.

Anyone know of SF Bay Area dealers who flash these phones?

Where can I get flash upgrade for my T616? I am so jealous!
