[Unanswered]  Beylogger failing to finish communication

Hey there fellow bladers.
So I'm having an issue with my beylogger and I'm struggling to find any solution for it, any help would be appreciated. 
So what's happening is I'm getting half way through the communication phase and then the communication stops, the beylogger flashes and then i get a message saying that the communication failed and i should try again. Ive tried dozens of resets and reloads of both the app and my phone and still nothing. The phone I'm using is an s7 and is still on android 6.0.1
Any ideas what the issue is?
