Is there a way of indefinitely listen downlink messages?

[matiassequeira]

Hi, I'm conducting a security research on lorawan and I have a Esp-32 device. I was wondering if it's possible to constantly listen to any downlink message on a certain downlink channel, in order to print all of them? Could you provide directions about which modifications should be done?

Best

This code contains the downlink processing function, and the downlink information received by the node will be printed out through the serial port.
