2 years ago void OnDataRecv(const uint8_t mac, const uint8_t incomingData, int len) { memcpy(&myData, incomingData, sizeof(myData)); Serial.print("Bytes received: "); Serial.println(len);
pulses = myData.a; // pulses incoming
}
It's difficult to see with out the whole code espnow is tricky....
I always store the incoming data before presenting it...

Using ESPNow in slave mode works perfectly, except when I try to use the writeln function. It prints one time, then hangs. If I remove the writeln function it continues to print to the console as expected. Any help would be appreciated.
void OnDataRecv(const uint8_t mac_addr, const uint8_t data, int data_len) { char macStr[18]; snprintf(macStr, sizeof(macStr), "%02x:%02x:%02x:%02x:%02x:%02x", mac_addr[0], mac_addr[1], mac_addr[2], mac_addr[3], mac_addr[4], mac_addr[5]); Serial.print("Last Packet Recv from: "); Serial.println(macStr); Serial.print("Last Packet Recv Data: "); Serial.println(data); Serial.println(""); writeln((GFXfont )&OpenSans24B, data, &temp1_cursor_x, &temp1_cursor_y, NULL); }
