Old APRS mechanism

Try to avoid using this mechanism, if you have the newer firmware that supports the new mechanism.

To disable this mechanism, set GPS Interval to Off (or 0) in the JSON editor.

There are 3 settings relating to this mechanism under the "DMR Service" menu in the manufacturer's CPS software. The channel you select under "GPS Channel" must have a default contact set, and that is the 'destination' that the APRS update will be sent to.

These are:

Under DMR Service:

GPS - On/Off - self explanatory, needs to be On for a position to be obtained and sent. (can be assigned to a hotkey) GPS Interval - how often the position updates are sent. GPS Channel - Which channel the DMR-APRS updates are sent to.

If ALL your DMR channels have a default contact specificed, the CPS software will allow you another option under GPS channel, which is "Current channel". This means that the DMR update will be sent to the channel the radio is currently tuned to.

So, to use the mechanism in the JSON codeplug:

Under DMR Service, specify something like:

    "GPS On/off": "On",
    "GPS Interval": 6,
    "GPS Channel group ID": 9,
    "GPS Channel channel ID": 2
},

Where the group ID and channel ID specify which channel you want the updates sent to.

Make sure that channel has a default contact specified, and that's the DMR ID that the update will be sent to.

So, for Brandmeister, UK Master, I specify 234999 as the contact for that channel.
