Minimum "external" GPS sentences

Hi, when using external GPS (in “track” mode), is there a minimum frame “set” required for proper operation? For instance, I am importing multiple sentences from my GPS simulator … [RMC,VTG,GGA,GLL etc] .. I filter out all sentences except for RMC for the Lat/Lon position. - this is the only sentence sent to the Notecard via AUX_RX input.. thus helping to reduce some overhead

regards, Rich

Hey @richf,

When using an external GPS we require GGA (lat, lon, ns, ew, fix, nsat, hdop) and RMC (lat, lon, ns, ew, time, date).

Hi TJ, thx for the response. Another question … is it possible to “programmically” remove all occurrences of the “_track.qo” entires in the notehub? ( i.e. clear out the tracks.)

regards, Rich ..
