Altering/disabling the GPS functionality does not mean that you will be unable to be found. Via triangulation of your radio, location may be given up to someone if they are determined enough.
GPS is provided by either the device or your paired phone. More than likely, you will want to keep GPS functionality operational. It is not required, but does assist in some of the time calculations at a bare minimum.
position_broadcast_secs when you set these to
0 you are not disabling these features.
gps_update_interval, the value
0 will be interpreted by the device as the default of 30 seconds. On
position_broadcast_secs the value
0 will be interpreted as the default of 15 minutes.
If you wish to disable any GPS features, see below for more information.
If set, this node is at a fixed position. The device will generate GPS updates at the regular
gps_update_interval, but use whatever the last lat/lon/alt it saved for the node. The lat/lon/alt can be set by an internal GPS or with the help of the mobile device's GPS.
Determines the amount of time that a GPS fix should be allowed to take. The default is every 30 seconds. If you increase this value, it will allow the device that amount of time in seconds to aquire coordinates. If the device is unable to get a fix, it will turn off until the next interval. GPS coordinates are updated every
How the GPS hardware in the device is operated.
This is independent of how our location is shared with other devices. For that see
|GpsOpUnset||Default: operates the same as |
|Note: This mode was removed, because it is identical go |
|GpsOpMobile||This node is mobile and we should get GPS position at a rate governed by |
|GpsOpTimeOnly||We should only use the GPS to get time (no location data should be acquired/stored) Once we have the time we treat |
|GpsOpDisabled||GPS is always turned off - this mode is not recommended - use |
Determines how often should the device should attempt to aquire a GPS position (in seconds). The length of time the device is allowed to attempt to aquire GPS coordinates each interval is set using
gps_attempt_time. The default is every 30 seconds.
Determines whether location is shared with other nodes. See more details.
|LocUnset||Default: operates the same as |
|LocEnabled||The device is sharing its location (or the paired phone's location)|
|LocDisabled||The device is not sharing its location (if the unit has a GPS it will default to only get time - i.e. |
How often our position is sent to the mesh (but only if it has changed significantly).
The gps updates will be sent out every
position_broadcast_secs, with either the actual gps location, or an empty location if no gps fix was achieved. This defaults to broadcast every 15 minutes.
gps_operation GpsOpTimeOnly is prefered to
gps_operation GpsOPDisabled because it allows the device to get a highres time.
Disabling location sharing does not disable the GPS functionality, only the location sharing via the mesh.
The device will continue to aquire GPS coordinates according to the
gps_update_interval, but will use the last saved coordinates as its fixed point.
It may take some time to see that the change has taken effect. The GPS location is updated according to the value specified on
gps_update_interval and the mesh will be notified of the new position in relation to the
