Bluetooth Connection Modifications: Windows 10

Windows 10 utilizes a workstation/device pairing mechanism for Bluetooth,

• The concept is similar to Mac OS X, although some specifics differ.
• From what I know, a Windows 10 workstation cannot communicate with a robot, unless a pairing has been established.

MyroC on Windows 10 can work directly with a MAC address. If that address is not fully specified, the connection process

• Uses a lookup service to run through all paired devices
• Finding the proper MAC address can take some time.
• Once a MAC address is found, programmers are advised to hardcode the address into rConnect

If not serial number is given, rConnect on Windows provides a listing of all paired robots, as is done with Mac OS X.

The MAC discovery process yields an appropriate address structure.
However, Bluetooth communication also requires determination of a port number.

• Bluetooth protocols allow port numbers 1-31.
• My investigation finds no reference to Windows functions that return what port number a robot expects.
• Without a mechanism to discover the port number directly, MyroC's rConnect tries port 1, port 2, ..., in sequence, until a useable number is found.
• In practice, connections usually are established on port numbers 1, 2, or 3.
