Problem LoRaWAN EU868 certification in Ukraine

[npham.1]

Hi everybody,

I have to problem with LoRaWan EU868 certify in Ukraine, specifically as follows:

I am using ABZ module as CMWX1ZZABZ-091 to develop product, and I set ABZ module such as:

+ firmware based on source code en.i-cube lrwan v1.3.0

+ used Lora modulation, EU868, BW 125kHz, ADR ON (SF12..SF7), class A, Tx UNCONFIRMED, OTAA, Tx power 14dBm

+ send packet by trigger and cyclic 10 minutes after last tx done, payload 10 bytes

+ set EU868_NUMB_CHANNELS_CF_LIST = 0 in file RegionEU868.h, so the module will only be used 3 EU868 default channels (868.1, 868.3 and 868.5MHz in SubBand G1)

=> To make type approval certificates in Ukraine

=> However, the test results appear frequency 890.375 Mhz, -37.86dBm as picture show (attached file)

I don't know what's wrong, please help us

Thank so much
