Unknown Date on Logs


We were trying to find and consider the logs file. We cannot see which date the logs belong to. It says Unknown date.

How can we solve it?


Hi @ugurdemirezen,

If you’re talking about dataflash logs, the BRD_RTC_TYPES parameter needs to be set to 3 to enable both GPS and MAVLink messages to be used as time sources for the vehicle, which then allows the vehicle to be told what time it is on startup.

Unfortunately while that parameter is not set the logs will save with Unknown Date titles.

You may be able to determine the approximate time of existing logs by counting back through QGC’s telemetry logs, which also may have the data you want already if you don’t need high frequency measurements.
