Intro to the hardware used in this course#
Throughout this course, we will be using the Raspberry Pi Pico W, Raspberry Pi's first wireless microcontroller board. It has been designed as a tiny and low-cost yet flexible development platform for the RP2040 MCU.
The 21 mm × 51 mm board comes with a 2.4GHz wireless LAN interface (802.11n). It provides 26 GPIO pins, three of which can function as analog inputs. Four RP2040 I/O pins are used for internal functions: driving an LED, on-board switch mode power supply power control, and sensing the system voltages.
Reprogramming the Pico W flash can be done using USB (simply drag and drop a file onto the Pico W, which appears as a mass storage device), or using the serial wire debug (SWD) port. The SWD port can also be used to debug code running on the RP2040 interactively.
Purchase hardware via Raspberry's website
Sensor used in the course#
In this course, we will be using the LM35 analog temperature sensor.
Purchase the sensor via Kiwi electronics (EU), Amazon (US) or Mouser (EU/US)
Intro to Anjay LwM2M Client#
Anjay is a free and open-source LwM2M Client written in C for rapidly building LwM2M solutions. It comes with an SDK comprising pre-built examples and reference implementations for popular hardware platforms such as STM32, Raspberry Pi, Nordic or ESP32. Anjay eases the development of LwM2M applications by taking care of the implementation of the LwM2M protocol.
The project was created and is actively maintained by AVSystem. Some expert features such as support for hardware security modules or SMS binding are available commercially.
Anjay features
- Automatically implements the LwM2M data format & Smart Objects
- Security by default (DTLS, OSCORE)
- Support for FOTA (firmware updates over the air)
- Device management mechanisms to update configurations over time vStandard implementations available for many hardware platforms
