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
