GTosPMU_App - PPS Enabled, Stops Running after a few seconds


The GTosPMU_App software stops running (receiving data) after a few seconds when PPS mode is enabled.

Possibly Related: GPS sync mode with PPS disabled does not work.

Host sync mode without PPS appears to work reliably.

Tested:Conditions = PPS Enabled, GTosPMU_App connected but not displaying data.Observations = 1) PPS signal continues to be transmitted by the GPS and measures properly by oscilloscope on the PMU's PPS pin.2) PMU Activity LED is steady ON, not blinking.

This problem is most likely a firmware bug.
