RN4020 hangs repsonds with A not AOK
I can send thousands of 'SUW,00004356475F53434D5F315F4254,1900,07D0\r' commands with the expected 'AOK\r\n' response. About every few minutes the RN4020 responds with only a single 'A', then hangs for about a minute before it becomes responsive again. Has anyone else seen a hang after getting only a single 'A' (from 'AOK\r\n') back? I've tried slowing the transmission down to a few ms between bytes, toggling wake lines and still this happens randomly without any recovery fix (other than waiting for it to snap out of its fit).
