Aws Iot Core , Configuration error coming from LNS to Gateway Band AU915 Brazil.

Hi pssimoes. I use AU915 (in Australia).

I haven't found a way to get the frequency settings sent by the WSS server

If you set log_level to XDEBUG in station.conf, the router_config message from the LNS is reported in the Basics Station log like this:

Good morning Greg B how are you?

I spent a few days without any feedback because I was trying to understand what was going on. And come to some conclusions...

When I put my gateway to communicate with the things network using lora_pkt_fwd it works correctly. It captures all packets of the AU915 subBand 1 frequency. Being operating in this way, it uses the global_conf.json file as configuration, I put a copy of this file in my google drive if you want to take a look. Follow the link below... https://drive.google.com/file/d/11ZLvcEaMFfwzQxY9wpOaM12MksdKvEvd/view?usp=sharing

Analyzing this file I noticed that the central frequencies start at 915600000 and 916300000 and that the rssi_offset is fixed at -166.

Here's the boot log, notice that radio 0 is set to center frequency at 915600000, and radio 1 at 916300000.

I managed to make my gateway print the json it is receiving from the aws LNS, for that I had to start the station with log level 0 with the following command...

/usr/bin/lora/station -h /etc/config/dusun/station/ -i /usr/bin/lora/reset_lgw.sh -l0 -t /tmp/

After messing with this command, I now have the print of the router_config

The full boot log can be seen at the link below... https://drive.google.com/file/d/1przEnPFp5aw3Nf4DCMQ0r70OJnspd35A/view?usp=sharing

What caught my attention is that the base frequency that is being provided by lns is different from the one that works in the case of the Things Network.

Radio 0 was set to frequency 915600000 Ok as expected. But radio 1 916600000 has a different frequency than the one that works here for us, it should be 916300000.

{"msgtype":"router_config","NetID":null,"JoinEUI":null,"region":"AU915","hwspec":"sx1301/1","freq_range":[915000000,928000000],"DRs":[[12,125,0],[11,125,0],[10,125,0],[9,125,0],[8,125,0],[7,125,0],[8,500,0],[-1,0,0],[12,500,1],[11,500,1],[10,500,1],[9,500,1],[8,500,0],[7,500,1],[-1,0,0],[-1,0,0]],"sx1301_conf":[{"radio_0":{"enable":true,"freq":915600000},"radio_1":{"enable":true,"freq":916600000},"chan_FSK":{"enable":false},"chan_Lora_std":{"enable":false,"radio":0,"if":0},"chan_multiSF_0":{"enable":true,"radio":0,"if":-400000},"chan_multiSF_1":{"enable":true,"radio":0,"if":-200000},"chan_multiSF_2":{"enable":true,"radio":0,"if":0},"chan_multiSF_3":{"enable":true,"radio":0,"if":200000},"chan_multiSF_4":{"enable":true,"radio":0,"if":400000},"chan_multiSF_5":{"enable":true,"radio":1,"if":-400000},"chan_multiSF_6":{"enable":true,"radio":1,"if":-200000},"chan_multiSF_7":{"enable":true,"radio":1,"if":0}}],"protocol":0,"regionid":0}

In summary, the gateway works normally communicating with The Things network, with the central frequency starting at 915600000 and 916300000. However, what is coming from AWS is different "freq_range":[915000000,928000000], even as a gateway registered in AU915 Subband 1.

Can I somehow act on what aws is sending to the gateway?

Thank you for your attention.

Greg B good morning how are you? I'll try to get help from the gateway manufacturer as it seems to be ok.

But the gateway is intermittent, sometimes it takes the packages and sometimes not.

Thank you for your attention.
