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.
On `gps_attempt_time`, `gps_update_interval`, &`position_broadcast_secs` when you set these to `0` you are not disabling these features.
On `gps_attempt_time` and `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 [`gps_update_interval`](#gps_update_interval) seconds.
| GpsOpUnset | **Default**: operates the same as `GpsOpMobile`. |
| ~~GpsOpStationary~~ | Note: This mode was removed, because it is identical go `GpsOpMobile` with a `gps_update_interval` of once per day This node is mostly stationary, we should try to get location only once per day, Once we have that position we should turn the GPS to sleep mode This is the recommended configuration for stationary 'router' nodes |
| GpsOpMobile | This node is mobile and we should get GPS position at a rate governed by `gps_update_interval` |
| GpsOpTimeOnly | We should only use the GPS to get time (no location data should be acquired/stored) Once we have the time we treat `gps_update_interval` as MAXINT (i.e. sleep forever) |
| GpsOpDisabled | GPS is always turned off - this mode is not recommended - use `GpsOpTimeOnly` instead. |
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`](#gps_attempt_time). The default is every 30 seconds.
| LocUnset | **Default**: operates the same as `LocEnabled`|
| 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. [`GpsOpTimeOnly`](#gps_operation)) |
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.
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 `position_broadcast_secs` value.
