Under the principle of ‘keep everything powered off unless explicitely asked to power it on’, I think we should default enable.gps and enable.gpstime to FALSE.

Thinking about the arrangement of a vehicle requiring GPS, perhaps this can be signalled somehow in vehicle.{h,cpp}? Have the vehicle module define there that it requires modem GPS and/or GPSTIME, and then have the nmea module enable appropriately? We can still retain modem/enable.gps(time) for explicitly enabling (I had a use case for this when a roadster owner on v2 had a broken car GPS, but the v2 tesla_roadster module doesn't enable the modem gps).

So the logic in nmea becomes: If ((vehicle module needs modem GPS)||(modem enable.gps)) Then enable gps.


The SIMCOM module now listens to these events:
If a vehicle needs GPS provided by the system, it does for example:

    MyEvents.SignalEvent("vehicle.require.gps", NULL);
    MyEvents.SignalEvent("vehicle.require.gpstime", NULL);

The SIMCOM module will in turn automatically power on and start the GPS subsystem as necessary, regardless of the "enable.gps" config. The signal normally will be added to the vehicle init but can be sent any time. The release signals can be used to shutdown the service when it's no longer needed.

The "simcom status" command shows both enabled & required status.

I've changed direction & altitude to float, missed those on the previous rework.

I've removed setting "m.time.utc" from the Twizy and Kia modules. On the Roadster, set "enable.gpstime" to "no".

I'm getting around 10 satellites all the time with my GSM antenna and our currently very snowy weather, so it seems we don't need active GPS antennas with this module. But I haven't had it on the road yet.

Michael

My GPS antenna is an active one for V2, it seems the current module does not support active antennas.

Actice GPS antennas are the standard choice over here. If the SIM5360 can do without, that will eliminate another energy drain, so is good. Users will need to know they'll need another antenna.

Michael
