How does an end device know which frequency a downlink will be on?
Reviewing https://www.thethingsnetwork.org/docs/lorawan/frequency-plans/, I see that The Things Network uses 9 uplink (“up to gateway”) (8 usable) channels and 8 downlink (“down to sensor”) channels...

How does an end device know which frequency a downlink will be on?
Looking at RP002-1.0.4, page 55, section 2.8.7, this defines the RX1 Channel Number: o RX1 Channel Number = Transmit Channel Number modulo NbChannel, where NbChannel is the number of active receive...

Definitely not a lawyer, don’t quote me on anything in court. A guess would be that according to spec, devices must be capable of using all 72 channels (RP002-1.0.4 page 50, lines 951-958) - and...
