[RAK7289] log question

[song]

We are testing communication between RAK3172 and gateway (thirpstack).

After an event message occurs in RAK3172 (SEND_CONFIRMED_FAILED(4)) during communication test, I checked the gateway logs.

“lgw_send failed on rf_chain 0 freq_hz 922700000” What does this mean?

Hi @song this can be caused by wrong configuration of the subbands used. If using UDP PF make sure the subbands in the gateway and chirp stack are the same. Make sure you are using the latest firmware for the gateway too.

Thanks to you, the problem was solved.

The problem was the uplink channel value of the Chirpstack network server.

So, if I set this channel value, is it okay to use it?

※ The gateway is RAK7289 V2.

Yes, it is absolutely ok. You have enabled all the channels in the NS.

Thank you so much Belev.
