Update RFLink gateway on Linux (Ubuntu)

RFLink is a great, flexible and opensource RF gateway for 433Mhz devices. I use it with Domoticz. Every few months, a new firmware is released and they add a lot of new devices. This post describe how to update an RFLink gateway in a Linux environment.

1. Software

Install AvrDude, an Atmel AVR microcontroller programmer :
sudo apt-get install avrdude

2. Update

1 – Plug the gateway (the Arduino Mega board) to your computer using an USB cable.
2 – Check the port :
dmesg

The output should give you something like
=
[ 2135.966103] usb 2-1.1: USB disconnect, device number 4
[ 2137.722793] usb 2-1.1: new full-speed USB device number 5 using ehci-pci
[ 2137.835663] usb 2-1.1: New USB device found, idVendor=2341, idProduct=0042
[ 2137.835667] usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=220
[ 2137.835670] usb 2-1.1: Manufacturer: Arduino (www.arduino.cc)
[ 2137.835672] usb 2-1.1: SerialNumber: 95431353438351916190
[ 2137.836212] cdc_acm 2-1.1:1.0: ttyACM0: USB ACM device

3 – Download and unzip the firmware from http://www.rflink.nl/blog2/download

4 – In the same folder than the extracted firmware, run the following command :
sudo avrdude -v -p atmega2560 -c stk500 -P /dev/ttyACM0 -b 115200 -D -U flash:w:RFLink.cpp.hex:i

The output should looks like this:
avrdude: Version 6.3

avrdude done. Thank you.

You’re done, happy home automation 🙂
