Nokia E72 vs W204 Bluetooth

[st13phil]

Just got myself a Nokia E72 and I'm having a weird problem with it's connectivity to the standard Bluetooth Telephony in my W204.

The problem is that at an indeterminate time into a call the car's connection to the phone mutes - both speaker and mic - and then drops. When it first happens the caller info is still displayed in the instrument cluster for the first few seconds, then the "Ready for Bluetooth Telephony..." appears and the Audio 20 fades in whichever audio source I was listening to before the call started, e.g. the radio. After a few seconds (something between 15 and 30), the connection re-establishes itself, the radio mutes again, and I can continue the call. The call will be OK for some random period and then this behaviour will repeat. Very strange...

My first thought was that it's a flaky Bluetooth implementation on the E72 (there are lots of posts on the Nokia forums complaining about Bluetooth headset disconnections with this phone), but the wierd thing is that when it happens and the call mutes in the car, the person on the other end of the phone gets whatever audio source I had running play over the air, which implies that the phone and the car are still communicating with eachother - just not in a very useful way!

I've used the W204's Bluetooth Telephony system with three previous phones (a Nokia 6300, a 6220 Classic, and more recently a BlackBerry 9500 Storm) over the last two years without ever experiencing this issue, so I'm fairly sure it's something to do with the E72. I'll try the E72 in Angie's SLK tomorrow and see what happens with that.

Go with your gut feeling

It's such a bad implementation that apparently it routes audio completely the wrong way, which is impressive.

You mean the Audio 20 appears to route audio from the radio etc. to the phone instead of from the microphone to the phone? This is how I understood it.

But I have not observed this in our car although I have not talked that much on the 204. Will have to ask the expert (wife ).

Is should have added that my wife is using a 6220 Classic too. I don't know anyone using an E72 in the car.

Hmm... That was what my research was suggesting. It appears that a later firmware release sorts many of the Bluetooth issues out, but - for whatever reason - the later firmware has been made available in the Asia-Pacific but not the European region

Yup, you understood correctly.

As I said, three previous phones have worked with the Audio 20's Bluetooth Telephony so it points to the new phone being the problem source

I don't know anyone using an E72 in the car.

Well, I've cured that omission in your life
