at_pico_w

Communicate with the atPlatform using a Raspberry Pi Pico W.

Developed with MicroPython.

Usage

Install the latest firmware.uf2 onto your Pico W from atsign-foundation/micropython Releases , as this is patched to enable AES CTR, which is used by atSigns.
Fill all the fields of the settings.json file (ssid/passw of your Wi-Fi network and atSign).
Run python3 build.py to generate .mpy files
Download Thonny IDE and place all the files of the built directory onto the Pico W file system.
Place your .atKeys file in the ~/.atsign/keys/ directory (if the folder doesn't exist, create it manually)
Run main.py and select option 3 in the REPL ("Get privateKey for @[yourAtSign]")
Re-launch the REPL (run main.py again)
Now you can select option 2 in the REPL to automatically get authenticated in your DESS
Enjoy! :)

(If you get an error when attempting to find the atServer or when trying to connect to it, run the REPL again)

Compile micropython with coverage enabled (to get AES CTR) and place the binary somewhere on the PATH (e.g. ~/.local/bin/)
micropython main.py
