Downlink frequency actually not written in sources, but computed on RX1 window setup as follow:

923300000 + ( uplink_channel_number % 8 ) * 600000

RX2 window channel is fixed:

Frequency: 923.3 Datarate: 8

Receive delay for RX1 window: 5sec

Receive delay for RX2 window: 6sec

Default uplink dwell time: 0

Default downlink dwell time: 0
