Using a Gateway to catch a downlink, or some other way to determine the link quality?

I know that GWs do not hear each other by default, but is there a possibility to change this?

Just in case you didn’t know: that’s due to something called “inverted I/Q”, which I think is also covered in LoRa Crash Course by Thomas Telkamp. Setting something like, e.g., DISABLE_INVERT_IQ_ON_RX may make a gateway hear another gateway’s transmissions, but I don’t know if it will then actually forward the received packets.

This might help too, but I’ve not looked at the code:

Bit of an old topic, but my lmic arduino port has a raw.ino example that makes two nodes talk to each other. It does somewhat abuse the lower-level functions of LMIC and bypasses the higher level, but it does work currently.
