General-motors-onstar protocol
Protocol used to to fetch vehicle telematics data via General Motors OnStar Data Services API.
flespi parses the General-motors-onstar protocol messages into a JSON object with the
fields listed below in the Parameters tab.
The channel consumes data using the Apache Pulsar client, which connects to the GM pulsar broker. Commands are sent through a HTTP request to the GM server.
To start receiving vehicle data from the GM OnStar telematics system perform the following steps:
1. Create a channel of ‘general-motors-onstar’ protocol. Contact your GM manager and ask for credentials to connect the pulsar client (to consume data) and to send commands.
Important note: In order for commands to General Motors OnStar devices to work properly, there must be only one ‘general-motors-onstar’ channel per flespi account.
2. Provide GM with the flespi outbound IP addresses 185.213.2.0/24, so that they whitelist them for inbound requests from the flespi platform to GM.
3. Once you have received the API credentials from GM, paste them into the channel configuration fields on the Edit tab:
4. Create General Motors OnStar devices in flespi for each vehicle that you want to receive telemetry for and use vehicle VIN as ident:
5. Execute the “provision_device” command (Commands & Settings tab) for each device to Opt In the device in GM for the listed services:
As soon as the command is executed successfully, the GM platform will start sending the vehicle telemetry data to the channel. You can see the incoming messages on the Logs & Messages tab.
