serial prints Peer channel is not equal to the home channel, send fail! esp32

This usually happens when you have connected it to a WiFi and it has been made to change channel after the library has initialised. Have you connected it to an AP?

This is definitely something the library handles poorly and I should make it check for.

can you please provide something about how to run this program like, is this RTC server important and all ??

I could solve the channel selection by forching wifi to reset in the setup():

WiFi.mode (WIFI_MODE_STA); WiFi.disconnect (false, true);

if(m2mMesh.begin()) { Serial.print("\n\nMesh started on channel:"); //m2mMesh. Serial.println(WiFi.channel()); }

Now I can change the default channel 1 with this:

include

include

include

include //to forche channel

void setup() {

Serial.begin(115200);

//////// WiFi.mode (WIFI_MODE_STA); WiFi.disconnect (false, true); //force channel 2 uint8_t channel = 2; esp_wifi_set_promiscuous(true); esp_wifi_set_channel(channel, WIFI_SECOND_CHAN_NONE); esp_wifi_set_promiscuous(false); //////

if(m2mMesh.begin(99,channel)) { Serial.print("\n\nMesh started on channel:"); //m2mMesh. Serial.println(WiFi.channel()); } else { Serial.println("\n\nMesh failed to start"); } }
