Dual-Chan Gateway with Raspberry PI3 + Dragino Hat v1.4 and Downstream messages

Thanks for the screenshots. my gateway outputs are the same but my node seems not to be getting anything. Is your node listening/sending on one frequency or all frequencies? Do you think I should the value my receive windows??
When a node sends on the frequency 868.1 does listen to the server reply on the same frequency? I asking because I have limited my node to send on a single channel. Is it wrong?

This function does not exist in my code LMIC_setClockError (MAX_CLOCK_ERROR * 10/100);
