Flashing Firmware and Changing IEEE on Sonoff ZBDongle-P

Hardware Preparation

1. Remove the cover from the ZBDongle-P
2. Enter bootloader mode:
   • Press and hold the boot button
   • While holding boot, press the reset button for 2 seconds, then release it
   • Release the boot button

Firmware Selection

1. Check the chipset compatibility guide: https://github.com/Koenkk/Z-Stack-firmware/blob/master/coordinator/README.md
2. For CC2652P chipset, download the CC1352P2_CC2652P_launchpad_coordinator zip file from: https://github.com/Koenkk/Z-Stack-firmware/releases
3. Extract the firmware zip file

Flashing Tool Setup

1. Clone the flashing tool: https://github.com/JelmerT/cc2538-bsl
2. Extract the firmware files to the cc2538-bsl project directory
3. For NixOS users: Get required Python packages

   nix-shell -p "python3.withPackages (ps: with ps; [ pyserial intelhex ])"

Flashing Process

Run the flashing command with your specific IEEE address:

sudo python cc2538_bsl/cc2538_bsl.py -p /dev/ttyUSB0 -evw CC1352P2_CC2652P_launchpad_coordinator_20250321.hex -i '0x00124b002e1dfa70'

Command Parameters

• -p /dev/ttyUSB0: Serial port (adjust if needed)
• -evw: Erase, verify, and write
• CC1352P2_CC2652P_launchpad_coordinator_20250321.hex: Firmware file
• -i '0x00124b002e1dfa70': Custom IEEE address

Notes

• Make sure the device is in bootloader mode before flashing
• Replace the IEEE address with your desired value
• Verify the correct serial port with dmesg or lsusb
