@Clive_A I'll post the screenshots of wireshark, it crashes on the key exchange

@Clive_A these are wireshark logs, I don't understand why port traffic 500 steps to port 40754, however it does not pass the key exchange request source:smartphone destination:192.168.2.2 Frame 1066:...

I'll check with wireshark and post the results
