Midi problem

Hi everyone,
I have a beat buddy connected to a pigtronix infinity looper. Been using the combo for quite awhile. Today for no reason the beat buddy is either not sending midi or the infinity is not recieving midi, out of the blue. I’ve checked the beat buddy midi out and it’s on. I 've rebooted both machines but that didn’t fix it. Do I need to update? I have 1.8.5 firmware in the beat buddy

Can you walk back any changes you might have made to either pedal? What are the symptoms for the looper not receiving or syncing to midi? Is the looper red LED not flashing with the BB metronome?
