Hi,

We were doing a project and everything was fine. We were able to send and receive message from the Computer.

Also, send and receive message from the Bluetooth module ( using PIC 24 in C code ). Now it’s just gone.

We can’t send any information to the Bluetooth module. It didn’t respond at all. Can’t get into Command mode.

“+++” didn’t work and we can’t see the Bluetooth device in our computer.

Can anyone help us ? Is there a way to RESET everything by circuit ?

Thanks

Ritchie
