    So I received a pair of Freakduino 900’s for Christmas and have been trying to use them but every time I do it comes up with Radio not initialized properly. I have tried both boards on different machines but I am getting the same result and I am using the Example 2 program for the testing.

    Im not too sure what to do with them at this point but I really want to use them because I know that there is lots of potential with them.

    If anyone could help, thank you

    Obsids, it is difficult to know what the problem is without seeing your code. But the example code I tried wasn’t working and I added chibiSetShortAddr(1); to the code for one of them, and chibiSetShortAddr(2); to the code for the other, and they started communicating. If you don’t have a line similar to that, you might try adding these lines to your setup code.

    Hi Walt.
    If both devices are coming up with that error, its likely you have the programming jumper populated. This jumper is only for programming the bootloader and should not be populated under normal operation. It would create the “Radio not initialized” error since it would interfere with the SPI bus which is used to communicate with the radio.

    [Update]
    The current 3.0 boards no longer have this programming jumper so the problem shouldn’t exist anymore.
