Nice screenshot.
What do you see is or isn’t happening?
Is the gateway configured to use GPS and emit beacons?
It seems that the GPS doesn’t work, I asked the gateway staff, I re-upgraded the firmware of the gateway, but it still seems to have the same effect. This is a screenshot of the new gateway log.
Also make sure the gateway is configured to transmit beacons. TTN provided configs do not switch it on (and by default it is off).
I do not seem to find the switch of bencon transmission in the gateway configuration interface.
It is a keyword : value pair in the local_conf.json or global_conf.json file.
This is the global conf.json I downloaded from TTN.

Do you see anything regarding beacons in that file? Probably not as I wrote yesterday. So you need to modify it to enable beacons.
Did you turn on beacon global_conf.json? I can compare. Now the problem is that I can’t seem to find the gateway beacon switch.
You could try googling, took me 5 minutes to find example global_conf.json files with beacon settings. Try something like “beacon”: true, in the gateway_conf part. If that doesn’t work there are other settings to try, check for instance the example at packet_forwarder/global_conf.json.US902.beacon at master · Lora-net/packet_forwarder · GitHub for beacon related settings.
Thank you very much, this lets me know it’s not the End-device code’s fault. I can’t use Google because of restrictions, so I have limited access to information. Thanks again.
This is the gateway’s generate-config.sh file for beacon Settings. After I changed it, nothing seems to have changed.

What are your gps settings?
Does your gateway have gps?
Can you read gps data?
Does gps get a lock?
Did you reach out Dragino?
Which is your gateway model?
Interesting article for adding gps support
I contacted Dragino’s engineer and she told me that GPS is turned on by default when PPS pairs are used. * I’m using LG308
This is generate-config.sh.
##GPS coordinates. use fake GPS from UI or via GPS module
if [ "$fake_gps" == "1" ];then
json_add_boolean "fake_gps" 1
json_add_double "ref_latitude" "$latitude"
json_add_double "ref_longitude" "$longitude"
json_add_double "ref_altitude" "$altitude"
elif [ "$model" == "DLOS8" ]|| [ "$model" == "LPS8-G" ] || [ "$model" == "DLOS8N" ];then
json_add_string "gps_tty_path" "/dev/ttyUSB0"
fi

And the config file that is generated looks like what?
Also you may want to try this.
Can you read gps data?
Does gps get a lock?
Have you tried this one?
beacon: true not found. The gateway staff says it supports Class B and has GPS, but it seems that the beacon pointing to the gateway is not working. Looks like we’re gonna need a new outdoor gateway.

Does this mean GPS data was not available?
How did you determine the system/hardware error rather than configuration problem?
More info may help others in a similar circumstance.
