iNode MCU GSM is a device with modifiable functionality, as it works under the control of the microPython ESP32 system - a script interpreter of the microPython programming language (based on Python 3.4). MicroPython is an open source system for the ESP32 SOC chip from Espressif. iNode MCU GSM combines three wireless technologies: GSM, Bluetooth 4.1 and WiFi. For your safety, the microPython firmware is digitally signed and can only be replaced via OTA. A relatively large amount of RAM (over 2 MB) and a file system of approximately 4.7 MB is enough to perform even very complex tasks. The device also contains a built-in hardware watchdog, which significantly increases the reliability of operation, which is so important in maintenance-free operating systems.

The user can write his own scripts in Python and enter them into the device. The iNodePy application serves this purpose. It works in the Chrome or Edge browser environment on Windows, Android or Linux devices. Communication with the iNode MCU GSM is wireless via Bluetooth. The application allows for intuitive access to the internal file system on the device. It is possible to save, delete, download and unpack files and executable scripts can be run. The technical support service offers the user free microPython scripts with various functionalities.
