I am working on a project to make the usart communication between an STM32 microcontroller and ZED EFR32M which communicates in zigbee with ZC EFR32. my problem I do not receive all my data on RX ZED, I receive the first three packets, and the fourth I receive only the last 5 bytes of the frame, I lose the beginning of the packets.
no it is in alarm clock, I receive well at the beginning 3 packet of 270 bytes.
in fact, the zigbee module is always in wake-up mode , I have configured that it always remains in wake-up mode
do you have an example please ?
I receive packets of 270 bytes and baudrate of 115200
