: We have bought a BTM-222 Bluetooth module, and we are evaluating it.
Unfortunately, we have configured it with a speed of 230400bps (ATL6).
The BTM-222 has saved this parameter.
Now, the PC can't communicate with the module anymore, the PC can handle
max. 115200bps. Even after a power off-on, the module stays @ 230400bps
and we can't send any command to it.
1.) Is there any solution to boot the module with the factory settings
(19200bps), when no command can be sent to it?
A:. You can pull PIO(4) to high for 3 seconds, that can restore default
baudrate(19200bps)
