I'm using an RN-42 Bluetooth module connected to the serial port of a PIC microcontroller.
The Bluetooth module works great and I'm able to send and receive data but when I send a BREAK (hold TX line to 0) from PC through Bluetooth the RN-42 seems not receive it and the TX line continue to stay at high level.
The data path is the following:
PC -> Bluetooth Dongle -> RN-42 Bluetooth module -> PIC Microcontroller
What could be the cause of this problem? Is this problem common to all Bluetooth modules?
