I powered the sensor HUB 2560 with his batteries and its impossible to find cell operators with the WisToolBox App and the “ATCELL+COPS=?” command.
In an attempt to solve it, I connected the Quectel module (RAK5860) via USB and sending “AT+COPS=?” I can see in a serial monitor that it returns the cellular operators so my question is, why it doesn’t work in the mobile app? Thats the reason why my sensor hub can’t connect to any operator?
