Firmware is set to instructions that ensure the proper functioning of a hardware device, which are updated from time to time for resolving the bugs.
Similarly, the Telit modules may need a firmware upgrade. This post explains how to flash the Firmware.
We will need a PC/Laptop with Windows OS for this task. The USB driver needs to be installed first.

Connect the Module to a Windows PC/Laptop with a Base HAT and run the executable file. ✅
