I try to connect from a PC (Vista SP1) to an BT module LMX9838 from National Semiconductor. The PC is the master an discovers the BT module and connects to it. Then I connect to the serial service of the module. This is always possible.
But when i try to open the stream, it sometimes works, sometimes not.
Then the error message is: 10060: BlueToolsException: Failed to connect remote Bluetooth service.
Please, can you help me with any idea?
Thanks in advance and best regards.
P.S.: I'm using Bluetools 220.127.116.118 together with the Microsoft stack.
