Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi,

Has anyone worked with HC-12 modules ? They default to 9600baud, and using AT commands you can change the baudrate.
Question is: do they memorize the baudrate ?

I have a remote system that cannot send data (init the HC-12) at 9600baud, so I need a PC to set the HC-12 to 2400baud, disconnect, and need it to cold boot after that running 2400 baud.

Thanks in advance for your response,

Volhout

Yes, they remember the set baudrate. Pull the SET line low to enter programming mode, when you pull the SET line high again, the new settings take effect, and are used if you cycle the power.
