The Blunt server makes good progress. I have sorted out the overall design: The Bluetooth stack is running in its own task as a server, and another class serves as one of the two clients. It is running in the NewtonScript task and implements an event handler. The server and the client communicate using events and messages, and the client is mostly used for non-communication tasks. The other client is the to be written CommTool which talks to the server as well using events and messages.
