OHS Arduino

OpenHayStack Arduino sketch

This sketch is based upon OpenHayStack main.c Firmware code for ESP32. https://github.com/seemoo-lab/openhaystack

Setup

• Open .ino in Arduino IDE
• EDIT actual adv key on line 27 with your key. Follow padding as shown on example (0x05)

Is it possibile to get a key creating a new accessory in OHS app e copy its advertising key. To generate a .key file with correct padding it'd useful what's on flash_esp.sh script on OHS main project.

echo "$PUBKEY" | python3 -m base64 -d - > "$KEYFILE" where PUBKEY is your adv_key and KEYFILE is your tmp.key blank file.
