Hi, I have a Vedex with bluetooth. It worked very well this week. But suddenly this happened:

[root@gumstix ~]# /etc/init.d/S30bluetooth start
Starting 32kHz clock...Settled
Starting Bluetooth subsystem:Trying baud rate 57600...
No response after reset
No response from BT module
Trying baud rate 921600...
No response after reset
No response from BT module
Trying baud rate 115200...
No response after reset
No response from BT module
Trying baud rate 57600...
No response after reset
No response from BT module
Can't initialize device: Success

Every else works well....

Whan can it be? Did it bluetooth chip burn?

Are there hardware tests I can make?

Thanks.
