What does AT+CERTIF command? (AT commands in I-CUBE-LRWAN for FCC certification)

Hello,

We designed a device with CMWX1ZZABZ-091 LoRa module on I-CUBE-LPWAN (Our FW is based on AT_Slave example).

Now we are in the middle of getting FCC certification and our certification lab asked us to provide a command for testing radio.

We recommended them to use AT+TTLRA command every time they need to send a packet, but it seems that they are not able to select a specific freq/channel to transmit on.

The only option they have is to select 868 or 915 MHz using AT+TCONF command.

We also found AT+CERTIF command but do not know what exactly it does. Can you describe it?

And maybe there is another AT command we can use for testing radio (transmitting on a specific channel for testing all channels separately)?

Thanks in advance!
