Event Driven Location Updates
Event Driven Location Update is a feature available on certain MOTOTRBO which, when enabled, will make the radio send a location update whenever a Telemetry VIO is triggered.
Normally, location updates are sent periodically, with the cadence set by the dispatcher using a dispatch application connected to the radio network (see LRRP). Telemetry messages are also otherwise sent whenever the state of a GPIO pin (configured as a Telemetry input) changes state or a programmable button is pressed.
With Event Driven Location Update, both the location and Telemetry VIO state are sent.
On most MOTOTRBO models, there are three or more Telemetry VIO inputs. These are available on the accessory connector. Triggering them requires a contact closure (e.g. switch) or the prerequisite triggering voltage. See Telemetry VIO.
It is not possible to trigger a location update by pressing a button configured for Telemetry.
Configuration
In order to support Event Driven Location Updates, the following needs to be configured in the radio:
- GNSS must be enabled (and available).
- A valid ARS Radio ID for ARS and location (as well as telemetry).
- At least one GPIO needs to be set to Telemetry VIO 1-5; the correct active level selected and GNSS report much be ticked (see below).
- The above telemetry VIO needs to be configured as required (see below).
The radio otherwise should be configured to work on the system in place (i.e. in terms of frequencies and channels).
