Ver 1.5 AT+CHE=2 not setting the correct sub band uplink channels #7

The AT+CHE to setup the sub band uplink channels is not working on version 1.5. I setup AT+CHE=2 (sub-band 2 US915, channels 8-15) 903.9 904.1 904.3 904.5 904.7 904.9 905.1 905.3 But the LSN50 are still using the frequencies on sub-band 1, channels 0-7.

Lets try this AT Command steps,

ATZ AT+ADR=0 -> replay should be OK AT+DR = 3 -> replay should be OK AT+CHE=<set your frequency transmit here, example 912100000> -> replay should be OK AT+NJM=0 -> should be OK (for ABP join mode) AT+CHE=2 finally ATZ again. check result with command AT+CFG, settings above must be proper on result.
