RE: BLE Peripheral Uart example get disconnected after bonding to windows. No way to reconnect

Hi Thanks for your answer Einar!

I found the solution to the problem. All the pairing process goes as expected but somehow once completed, Windows disconnect it. I tried to use another BLE software (Bluetooth LE Explorer) to try to connect once paired and it worked!
Windows only needed a manual re-connect request even if I thought that once paired, this would be automatic.

Hi,

The disconnect reason here is 19 = 0x13 = Remote User Terminated Connection. So the peer (Windows computer) decided to disconnect for some reason.

[quote user=""]I went through the Windows event viewer and I always found some of these events when I was testing the BLE Connection. Messages in the Event Viewer seemed to changed based on the appearance number.[/quote]

The log you see here from Windows seems to explain what you are experiencing, but I have never seen anything like it nor am I able to digg into internals of the Windows Bluetooth stack. I suggest you contact Microsoft for assistance about this.
