Telemetry info frozen, four green lights with flashing red


During a dive yesterday, my Trident’s telemetry data froze on the display. The video and controls otherwise continued behaving normally. We recovered the drone, and it had four green tail lights illuminated with a constant flashing red.

We restarted the drone, which fixed things for a few minutes, but then the same problem returned – locked up telemetry data, flashing red light and 4 solid green lights. Further restarts did not fix the problem.

Couldn’t find any troubleshooting information in the documentation. Does anyone have any info on this error?
