error esp now

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

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 <Arduino.h>
#include <m2mMesh.h>
#include <WiFi.h>
#include <esp_wifi.h> //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");
}
}
