What information do I need to diagnose intermittent server communication issues

Intermittent server communication issues may occur. Accurate diagnosis is the first step, and the information gathered is crucial to analyze behavior and identify patterns for a solution.

Explanation:

There are many possible causes for intermittent communication with the main server. These may include GNSS or GSM signal issues, SIM card problems, or even server communication certificate errors.

When this type of issue occurs, it is important to validate which other communication channels are available to collect all related information. In some cases, the root cause may also lie on the server side.

Guidelines:

  1. General details to collect:

    1. Installation date and issue occurrence date

    2. Geographical region of the device(s)

    3. SIM card details (local or multicarrier operator)

    4. Frequency or timing pattern of the issue

    5. Confirm if SMS communication is available

    6. Were there any firmware (FW) or configuration (CFG) changes made before the issue appeared?

    7. Presence of memory events after server communication was restored

  2. Device Information:

    1. Firmware version

    2. Configuration (CFG) version

    3. Hardware version

    4. List of affected devices and their IMEIs

  3. Communication validation:

    1. Check availability of diagnostic commands: coords, gsminfo and getlog 92.62.134.14,10103,1,60

      1. This specific getlog command generates a 60 minute log on our server. For proper evaluation, it is necessary to provide the date when this command was sent along with the corresponding IMEI to the technical support team

    2. Does a command reset restore server communication?

  4. Configuration (CFG) checks:

    1. Validate server configuration settings

    2. Verify data generation and sending frequency

    3. Review data sending parameters, hibernation options and SSL settings (if they are used)

  5. Server report validation:

    1. Obtain a server report containing:

      1. Server timestamp vs. GPS timestamp (to validate memory events)

      2. IO parameters: GSM signal, HDOP, satellite count, cellular operator, ignition status, main voltage, movement sensor, device uptime

      3. GPS data: coordinates, speed, altitude
