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 :
|
1 |
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 :
|
1 |
dmesg |
The output should give you something like
|
1 2 3 4 5 6 7 8 |
= [ 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 :
|
1 |
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:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 |

You’re done, happy home automation 🙂
