FT101_Decoder.js does not pass Lat/Long in payload

[techfixpros]

FT101
LoRaWAN Version 1.0.3
Work Mode Class A
Join Type OTAA
App Version 1.0.4
Firmware Version 1.3
Hardware Version 1.0

FT101 is onboarded and communicating with LNS, and codec is properly decoding. Values passed in payload are:

Status, FW Version HW Version, IPSO Version, Serial, TSL Version, RSSI, SF, SNR, and Tx Power.

Latitude and Longitude are displayed in FT101 app while running Signal Evaluation, Real-Time Testing, and Noise Scan, and are included in the exported reports. Inclusion of Lat/Long in the payload will allow 3rd party integration with application server and provide mapping abilities outside of the current exported report method. The decoder already has a function detailing that Lat/Long should/could be decoded from the uplink.

} // LOCATION else if (channel_id === 0x03 && channel_type === 0xa1) { decoded.longitude = readInt32LE(bytes.slice(i, i + 4)) / 1000000; decoded.latitude = readInt32LE(bytes.slice(i + 4, i + 8)) / 1000000; i += 8; }

Starting from version v1.0.3, the Field Tester app automatically reports test results when you click Stop after running the Real-Time Testing feature. These results should include latitude and longitude values (up to 6 decimal places). I just tested this on my device, and the reported data does include the coordinates. You can try running the feature to verify.

I will try to try it again this week. The tester is on 1.0.3, and I downloaded a fresh copy and upgraded again in case I had a bugged version. Ran numerous tests in real-time last week, and prior-to deleted the latitude and longitude from chirpstack measurement page to see if the two data points were discovered. They were not.

I may delete the device and re-onboard it, and test again. The exported .csv do have the correct lat/long.

It did emit the objects when stopping the Real-Time Testing, but although the app shows the Lat/Long correctly, the payload only shows 0 for the values.

"data": "A6EAAAAAAAAAAASiR/0jAAWjCQakuAs=",
"object": {
    "snr": 3.5,
    "sf": 9,
    "longitude": 0,
    "rssi": -69.7,
    "latitude": 0,
    "tx_power": 30
},

I am also requesting the Lat/Long to be sent on every uplink, in order to do coverage mapping, instead of just when the RT Test is stopped.

Regarding the Latitude/Longitude Issue
Could you please help provide the log file so we can investigate further?
Here’s how to retrieve it:

Tap the App Version (e.g., v1.0.4) five times quickly to enable Debug Mode.

Restart the app.

Run the Real-Time Testing feature again.

Go to Settings > Log, and tap Download.

The log file will be saved to your device’s Download folder.

Regarding Location Data on Every Uplink
At this time, the device only reports latitude and longitude when Real-Time Testing is stopped.
It does not include location info in every uplink report.
