GPS NMEA port stops responding after 3 minutes

IoT Modules MC/EM Series
6

Hmmm… good thought I tried changing this to 30 seconds and power cycling the modem but the port still stops after 3 minutes

at!gpsautostart?
  function:  2
  fixtype: 1
  maxtime: 30 seconds
  maxdist: 50 meters
  fixrate: 1 seconds

OK

The weird thing is that the location is being still being updated through the AT query, so I don’t think the fix is timing out
