Thanks again MoFoQ. Glad to hear logging is getting better.

Status=-1 means one of the connection operations (connection or characteristic discovery) timed out. This happens a rather frustrating amount to me as well even when testing, but it’s related to bugs in the Android stack. It varies from handset manufacturer to handset manufacturer though. Sorry I can’t say anything more informative here… I don’t have a magic bullet for that one :)

Thanks again for all the great feedback. Best
