I am working on an agricultural automation project and as a part of it right now I am testing simplex Lora communication between 2 ESP32 with RA-02 units: one as sender and the second one as receiver. I am using the default configuration of the RA-02, I’m sending a message every second, the emitter and receiver are side by side on my desk, RSSI is -26 and SNR 9. Everything runs quite well, but from time to time the receiver gets a corrupt message (201 times in 25900 messages) and deserialization library gives an error. After the error, communication continues till next error.
I am quite experienced with ESP32 but I am new to Lora and probably I am missing something basic, but … any idea about what should I do to avoid these communication errors ? Any hint ?
Thanks and best regards
