Firmware is software stored in a device’s memory. It determines how the module communicates with the GSM/LTE network, how it records data from sensors and how it transmits this data – for example, to a master system, the cloud or an app. In practice, it is the foundation upon which the reliable operation of the entire telemetry system rests.

Data transmission security
Telemetry and monitoring rely on the continuous exchange of information. Firmware updates fix detected vulnerabilities and enhance the security of data transmitted by the module – ensuring that the user can be confident that communication with the system is secure.

New features and support for new solutions
Updates often introduce extended support for transmission protocols (e.g. MQTT, M-Bus, SNMP, FTP), new features in the PLC programming module, integration with new platforms, or improvements related to energy management. This enables the module to meet the requirements that arise as telemetry systems evolve.

Stability and reliability in continuous operation
Telemetry devices operate 24/7 – any interruption in communication can result in the loss of critical data. Updates eliminate errors and improve performance in various scenarios, which translates into more reliable operation in the long term.

Compatibility with networks and operators
Mobile technologies are evolving rapidly – operators’ requirements are changing as they update their services and equipment. Firmware updates ensure that the modules remain fully compatible with current solutions.

A telemetry system was installed in 2014 and operated fault-free for many years. It was only recently that the user noticed gaps in data transmission on the SCADA system’s synoptic diagrams. The devices’ power supply was functioning correctly, yet initially, data was not reaching the system at intervals.

The first thought? A fault on the part of the mobile network operator. However, a detailed analysis revealed that the devices were still running the software from the time of their initial installation. Over the years, there had been no need for changes – the system had been operating stably, so the issue of an update had not been raised.
It turned out, however, that the transmission networks had changed in the meantime. The older firmware could not cope with the new parameters and requirements of the telecoms operators. As a result, communication became unstable and the system effectively ceased to function.

The solution was to update the software in the central module, which is responsible for data collection. Once this was carried out, transmission was restored and the system returned to full working order. The update was also carried out at the other sites, which resolved the issue across the entire infrastructure.

Updating the software in telemetry modules is a simple and safe process, provided it is carried out in accordance with the recommendations.

Update steps:
Check the software version

• Read the device’s current configuration via the configuration port (USB/RS-232) or remotely using the MTManager software.
• Check the firmware version number (parameter in the General group).

Download the latest firmware

• The latest file is available in the MTManager software (downloadable from the support section on inventia.pl; it is also available remotely via automatic updates using an FTP connection
• A change log is also available on inventia.pl, detailing new features and fixes.
• Remember: always use official sources.

Verify the backup of the configuration and programme

• Make a backup of the configuration and programme before updating.
• Depending on the firmware version, the update may partially or completely delete the configuration profile and the PLC’s internal programme.
• After the update, load the target configuration and programme so that the device resumes operation in accordance with the previous settings.

Prepare the update environment

• Ensure the device has a stable power supply.
• Local update: computer + communication cable + MTManager software.
• Remote update: check that the device is correctly logged into the GSM/LTE network.

Install the new firmware

• Launch the update application and select the firmware file.
• The process takes a few minutes – do not disconnect the power supply or interrupt the communication.

Restart and verification

• Once complete, the device will restart.
• Check the firmware version number.
• Load the previously saved configuration and programme.
• Verify that the host system (e.g. SCADA, DataPortal) is functioning correctly.

A firmware update is not just a ‘maintenance requirement’. It is a tangible enhancement to security, a guarantee of operational stability and an opportunity to utilise new features
in the telemetry and location modules on offer.
Regular updates ensure that your investment in a telemetry system will operate reliably and in line with current technological requirements.
