I need a little confirmation. When joining during OTAA, Is the LMIC library choosing two random channels among the three mandatory channels defined in the specification? I've done several Join before but each time I had the 868.3 MhZ SF8 used. But this time (see below), I only have 868.1MHz and 868.5 MHz SF8 channels used. However it seems that my dual_chan_pkt_fwd (gateway) is only working with 868.3 MHz.
As i can see in every OTAA, the join is using 2 frequencies for one SF then it changes the SF and re-start with two new frequencies.
