Troubleshooting

Following are some of the common errors and related information.

Connection

Error code -22

Verify the client ID, the endpoint and the certificates.

Cellular connection

Since 5G support is currently being deployed by mobile phone network operators, there is a high chance of connection issues in your location.

It is generally recommended to try multiple SIM cards from different vendors in case you experience connectivity issues.

GPS

Error: GPS_EVT_OPERATION_BLOCKED

This error occurs if the network provider does not grant Power Saving Mode (PSM) and the GPS takes a long time to acquire a fix. For more details, see the DevZone post related to GPS and LTE issue.

A solution is to switch to a SIM card that grants PSM.

Another solution is to use assisted GPS (A-GPS) to speed up the time to fix. Currently there is no support for A-GPS in Bifravst.
