# GPS:
|
|
# - enable: `mmcli --modem any --location-enable-gps-unmanaged`
|
|
# - or `mmcli -m any --location-enable-gps-nmea`
|
|
# - or use `systemctl start eg25-control-gps`
|
|
# - verify GPS is enabled: `mmcli --modem any --location-status`
|
|
# - query GPS coordinates: `mmcli -m any --location-get`
|
|
# - monitor constellation info: `mmcli -m any --location-monitor`
|
|
# - i.e. which satellites are in view
|
|
# - or just `cat /dev/ttyUSB1`
|
|
#
|
|
# interactions, warnings:
|
|
# - Geoclue (`where-am-i`) toggles mmcli GPS on/off every 60s, often resetting it to the "off" state
|
|
# - see: <https://gitlab.freedesktop.org/geoclue/geoclue/-/issues/180>
|
|
# - the effect is that GPS data is effectively useless inside apps like gnome-maps
|
|
# i think the trick is to get "--location-enable-gps-unmanaged" gps working again
|
|
# or use gnss-share/gpsd (this may be what "unmanaged" means).
