RN4020 periodically crashing
I know this is an old forum but I have the same issue with a RN4020 with version 1.10.09.
I have set up a private service which has 'Notify' property. I write to the characteristic every 74mS and receive an 'AOK' response. But at random intervals I only receive 'A' and the RN4020 is non-responsive. Eventually it will restart itself and prompt 'CMD'.
Was there ever a conclusion to the cause of this similar issue and a resolution to it?
