I'm trying to get the MailboxNotifier code working on an R3 MotionMote board and R6 Moetino. I keep getting the error message "Category 'Wireless Communications' in library RFM69_LowPowerLab is not valid. Setting to 'Uncategorized'" when trying to verify the code. I'm using the latest IDE, and got the latest RFM69, LowPower libraries from GitHub. I went back to the example MailboxNotifier code from the examples in the RFM69 library, modified it for 433mhz, and still get the error.
I get the same error trying to set up the code for the OLED Motion Mote receiver.
I'm at a loss at this point. I'm not sure if I've missed a setting or have something in the wrong place, or what.
