Protocol used by GPS tracking devices manufactured by Sierra Wireless Inc. headquartered in Canada.
flespi parses the Sierrawireless protocol messages into a JSON object with the
fields listed below in the Parameters tab.
To connect your tracker using the Sierra Wireless protocol, you need to have a sierrawireless channel created first.
Point your tracker to the channel's domain name:port via SMS or configuration tool provided by the vendor.
Then create a device instance for your tracker and use a Serial Number without leading zeroes in the ident field.
Use the Logs & Messages tab on the device screen to check if the messages are coming.
To connect Sierra Wireless to Wialon or another platform via flespi please read this article.
Report configuration
Report Columns of the device must be configured to have column 28 Serial Number at the first place, as Serial Number is used as unique identifier of GNX device. Report Columns configuration example:
REPORT_COLUMNS=28.3.4.7.8.10.11.13.17.23.36.130.82.46.41.61.56.70.93.74.75.77.89.90.112.113.99.141.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0;
Parsing of telematics reports is performed according to the Report Columns setting of the device. Important: If you changed the report composition in any way other than via the flespi setting (e.g. via SMS or Serial Port), you need to synchronize the setting with the flespi device. To do this, click the "Request setting from device" (red round arrow) button for the Report Columns setting.
