Conflict between IotWebConf and Painless mesh

[hesama110]

I am trying to have a mesh network which one of them is Gateway and it need to be connect to WIFI and internet to transfer data by MQTT. I am using PainlessMesh to create the mesh. Issue I have When I am adding IotWebConf setting as minimal version to start with, some times it isn't showing any access point, some times showing ESP-xxxx, if AP name show up in wifi list in PC. I couldn't understand why it is not connecting to WIFI My simplified code is here, please let me know what can be wrong

I'm not sure about this, but mesh network might also tries to manage the WiFi connection as IotWebConf does. In this case you are not able to use both of them. (I wanted to separate the config section from the WiFi-management section, but it will not happen in the near future.)

As a general rule you might want to use standard the WiFi.begin() and WiFi.softAP() methods to test whether these work properly with the corresponding library, as IotWebConf uses these basic methods to operate the WiFi radio.
