If from the 24th to 48th hour, end node got an downlink from server, it will switch back to unconfirmed uplink. end node will restart ACK_Timout_1. If from the 24th to 48th hour, end node still not got any downlink, means device doesn't get ACK from server within last 48 hours. Device will process rejoin, rejoin request interval is AT+RJTDC period. For AU915/ US915, device will use the sub-band used for last join.
