I'm sending data (99) to the Master that is in COMBO mode, When the Master receives this Data (99) is will tell the Master to send different Data (dt=1or 0) to other Slaves. The Master worked fine before I turned it into a COMBO adding the receive Code. I've been trying some different codes to get it to work but the Master will not receive the Code from the other Master as far as I can tell. I will post both Codes here labeled MasterTX and MasterTXRX (COMBO). This is currently just Blinking onboard LED'S to show activities of the boards, the MasterTXRX led just stay's on, not showing any activity, so no Data being received. Any help would be appreciated.
Shelley.
