Update the RFLink gateway using CLI on your Linux server. We’ll see how to update a RFLink gateway running on an Arduino Mega without having to disconnect it from your Linux server (Home Assistant or Domoticz).
The RFLink Gateway is an open-source platform that acts as a bridge between 433MHz sensors and other smart home systems, such as Home Assistant or Domoticz.
By using RFLink, users can integrate a wide variety of 433MHz sensors with their home automation ecosystem, enabling seamless control and monitoring of devices like door/window sensors, temperature sensors, and motion detectors. This gateway simplifies the setup process, providing compatibility with many different sensor brands and protocols. RFLink enhances the versatility and interoperability of 433MHz-based devices, contributing to more efficient and connected smart home environments.
Software on the Linux server to update RFLink Gateway
Install Avrdude :
sudo apt-get install avrdude

Update RFLink Gateway with CLI
Stop domoticz :
sudo service domoticz stop
Then upload it on the Arduino :
sudo avrdude -v -p atmega2560 -c stk500 -P /dev/ttyACM0 -b 115200 -D -U flash:w:RFLink.cpp.hex:i
