ATrack AL11
Flespi parses telemetry data from your ATrack AL11 into a standardized JSON and
lets you send commands to ATrack AL11 via API.
Here’s the like of JSON you get
{
"ident": "352625333222111",
"position.altitude": 273.61,
"position.hdop": 0.7,
"position.latitude": 49.069782,
"position.longitude": 28.632826,
"position.satellites": 18,
"server.timestamp": 1650636570.426424,
"timestamp": 1650636570.426424,
"device.type.id": "ATrack AL11",
"channel.id": 1111,
"protocol.id": "atrack"

...
}
How to consume this nice JSON
The easiest way is to make a REST API request like this
curl -X GET --header 'Authorization: FlespiToken XXX' 'https://flespi.io/gw/devices/<device id>/messages'
