RAK5860 Not responding any AT commands

You need a battery for reliable function of the RAK5860
Hardware Setup


This is valid for both Base Boards.
It might work on the older RAK5005-O without battery, but you cannot rely on it. It might fail at any time.

Reason is the high current consumption of the cellular chip. There might be a brown-out at any time and the Quectel chip is shutting down or malfunction. Specially while it tries to connect to a cellular network.

I see, any improvement in sight/planned? some cellular module that could be used instead of BG77?

All cellular modems I know have the same problem. High power consumption when connecting/sending/receiving.

We are not planning any other cellular module for WisBlock at the moment.
