easyRadio i2c setup help

Hey guys

I'm new to the forums and fairly new to arduino overall. I have been searching on google for multiple hours without luck, so therefore I hope some clever mind on this forums might be able to help me out.

I have 2 mini pro arduinos and 1 leonardo. I have 3 pairs of these: Radios. I want to be able to send information (in form of string or whatever) from the 2 minis (individually) to the leonardo, for it to work with, using the easyRadios. I was able to setup a standard wired i2c connection but I have yet to be able to figure out how to make a similar setup with the radios. I need help for both the code or the exact setup.

Thanks in advance


Do you need code for the I2C ?
This is a good start, Gammon Forum : Electronics : Microprocessors : I2C - Two-Wire Peripheral Interface - for Arduino

Do you know if the EasyRadios already contain firmware ?
This is the manufacturers page for them, http://www.lprs.co.uk/easy-radio/modules/
You have to read the documentation, they have also a document for the Arduino.
After a quick look, I think they are not easy. At least the documents are not clear how to interface them.

You could use these very cheap modules with the VirtualWire library:

They seem to be sophisticated 19.2K baud transceivers with some really nice features like an RSSI based CD (carrier detect)… With configuring software… I attached the data sheet. Definately NOT in the “Simple 433 MHz” crystal radio (The “Simple 433 MHz” transmitter is a saw filter (Surface Acoustic Wave) crystal filter with some gain wrapped around it to make it oscillate @ 433.92 MHz
