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).
• Download Thonny IDE and place all the files of this repository in the Pico W file system.
• Place your .atKeys file in the ~/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 secondary or when trying to connect to it, run again the REPL)

(You can uncomment a few commented lines in the send_verb method to see the llookup verb answer content decrypted. Warning: some stored keys are not encrypted, if you try to see the decrypted content of one of those stored keys, you will get an error. This exception will be handled in the future)
