2 x ESP-C3s not communicating using ESP-NOW

[eyanson]

Hi, I think my issue may be related.

I am using an ESP32-C3 Super Mini and an ESP32-S3-N16R8. ESP-NOW works from S3 to C3, but not from C3 to S3. I also tried broadcast with the same sketch on both boards: the C3 receives the S3 packets, but the S3 never enters the RX callback.

I posted the full debug and code here:

ESP-NOW between ESP32-S3 and ESP32-C3 works only one way

ESP-NOW broadcast: ESP32-S3 receives nothing from ESP32-C3, but ESP32-C3 receives from ESP32-S3 Hi everyone, I am having a strange ESP-NOW issue when mixing an ESP32-S3 and an ESP32-C3. The communication only works in one direction: ESP32-S3 -> ESP32-C3: works ESP32-C3 -> ESP32-S3: does not work I simplified the test as much as possible. I am now using the same broadcast sketch on both boards. Both boards send a broadcast packet every 2 seconds, and both boards register a receive callback. …

Maybe both problems are related. It would be good to keep the threads linked in case one of us finds the solution.
