To turn the Raspberry Pi Pico into an Internet of Things (IoT) device, you need to add wireless connectivity. I thought I’d give it go, to see how straightforward it might be to connect the Pico to cellular networks and have a bare-metal app written in C++ run the show. For a modem, I chose to use Waveshare’s suitably sized Pico SIM7080G Cat-M1/NB-IoT.
