TAT240 repeats same telemetry until SD card formatted

[Ben-Gradient]

I have a TAT240 that is sending the same telemetry over and over, until i connect it to USB and use the Configurator to format its SD card.

The repeated telemetry is the same AVL packet, repeated whenever the TAT240 is scheduled to send. These messages all carry the same timestamp, latitude and longitude as the original, even though the TAT240 may have moved to a new location. It is located outdoors with a clear view of the sky and when I check its Status using the Configurator the GNSS is reporting correct latitude and longitude, but when I force it to send a packet using the ‘Test Connection’ button, it just repeats the old packet with the old timestamp and lat/lon, UNLESS I format the SD card first, in which case it will send a packet with the correct timestamp and lat/lon.

Any ideas on how to rectify? Thanks.

Hello @Ben-Gradient
Good day!

This is due to the wrong server response,

The server should respond to the device after every record received from the device, In this case, if the response is correct, then the device will delete this record from the storage and send the newest ones

Thank you, this was the issue with our server. We added the logic to respond to the TAT240 and it solved the issue.
