I am running a RAK3172 ESP32 combo. The ESP32 runs Micropython and talks to the RAK3172 over UART. This all works fine.
However, I cannot get the RAK3172 to receive downlinks in Class C mode. It is as if it stays in Class A. It receives the downlink in the RX windows after an uplink. I would expect it to have the RX window open and receive the downlink anytime when in Class C.
So I need assistance in troubleshooting the setup, as well as understanding how exactly the Class C mode works through the AT command set. Do I have to issue
AT+RECV=? to check if something was received, or will the received downlink pop up on the UART. If neither of these, I do I get the receive downlink?
Any ideas and help with be much appreciated!
