Hi,
About the stm32wl55 subGHz module. I choose FSK mode because of his higher flow rate than LORA. Question what is the preamble, i know his length can be tuned but what it is ?
Regards

A data pattern the receiver can recognize and synchronize too. Also allows the early recognition of two transmitters stepping on each other for abort/retry over channel ownership. Generally transmitters look for the channel to be free/clear before starting as the medium is shared.

sequence of 1.0 for FSK
0 for LORA
