I started to work with UgCS client and server a couple of days back. 

I could create connection to the UgCS server and I could also subscribe to the vehicle to receive telemetry data. 

Problem is, When I receive the telemetry data, it is not complete.

First Message I receive contains 10 telemetry type values. But later, I only receive ROLL, PITCH, HEADING.

I tried to check the vehicle data using the UgCS example application and it happens there as well. 

Could anyone tell me why I couldn't receive all telemetry values everytime?

Any help on this is much appreciated. 

Thanks.

  • Thanks for the reply Stevod.

    I agree that, UCS returns the value only when the change of that particular is updated. May I know why I'm not receiving all the telemetry at first? The first telemetry I receive contains 10 values whereas expected is almost 90. know how?

    By default, the telemetry that is returned is not complete, in that it does not every value, every time. Instead, it returns only values that have changed. 

    However, I think there is a telemetry setting in one of the config files that allows it to be set to return every value, every time (at least when using the emulator drone).

    I suggest you review the config files - it should be fairly obvious.

  • UgCS uses incremental telemetry updates. Each time telemetry field is sent, it is the new value for that field. If a field is not sent, it means the previous value is still valid.
