Another OS for IoT applications called Mongoose OS. Like the other OS’s for IoT, Mongoose OS has some security features like:
- Microchip ECC508A crypto chip support.
- Supporting mbedTLS library from ARM.
- Implementation of file system encryption and full SPI-flash encryption on ESP32.
Mongoose implements the API for: HTTP, WebSocket, MQTT and CoAP; for both client and server and with a rich API and a tiny footprint. Moreover, it integrates with Amazon AWS IoT service, Google IoT Core and Adafruit IO online service.
For device management and firmware building Mongoose uses a tool called mos. This tool works in Windows and Linux as a command line interface or a web UI.
In the video below there is an example of running a built-in web server using ESP WiFi module.
Last but not least, Mongoose supports the following hardware interfaces: Bitbang, GPIO, I2C, NeoPixel, SPI and UART. It can also performs remote management for the device such as: file system (list, get, put and remove), configuration, I2C, GPIO and OTA
An example of upgrading the firmware over the air (OTA) is explained in the video below :
