RFLink-ESP Firmware Flashing Guide

Downloading firmwares

Releases can be found here

Nightly/Development releases are the latest firmware compiled from the latest commits. They are the only ones available today in this early stage of the project.

The following files are at your disposal:

• esp32-firmware-OTA.bin: to upgrade existing RFLink-ESP devices
• esp32-full.img: to flash a new device or erase a previous installation
• sonoff_bridge-firmware.img: firmware for the Sonoff RF Bridge

First time flash or full reset

If you have already installed RFLink on your device, beware the following will overwrite all your existing configuration. Please have a look at the OTA Update if you just looking to upgrade an existing RFLink-ESP device!

Using Esptool:

If you have not yet installed the 'esptool' module for python:

python -m pip install esptool

Erase flash entirely to ensure nothing will go wrong

python esptool.py --chip esp32 --baud 460800 erase_flash

Install the firmware

python esptool.py --chip esp32 --baud 460800 write_flash -z 0x1000 esp32-full.img

Subsequent updates should be done via the OTA mechanism.

OTA updates

While this procedure is not supposed to overwrite your existing configuration, we strongly advise you to make a backup of your configuration first!
