Hi,
Yes, it is possible to use WCL UUID (from sample).
1. Yes
2. I think it is better to refer to BS help file (in my case it is in settings->services).
You are mixing up different things. BlueChatServer and SPP are different things. You canuse SPP UUID for chat server/client or can use any other. if you use SPP UUID then it can bring some issues as you had.
