We successfully use Windows Sockets for Bluetooth for connection to our devices in В Windows XP SP3, Windows 7, 8, Windows 10 version 1703. However, we cannot connect to them in Windows 10 version 1809. Function “connect” from “socket” exits with error 0x0000274c "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond". Windows 10 version 1809 is able to discover our remote device, add to system, but RFCOMM SPP connection is not set. Possible issue is that remote device based on CSR-BC417 chip does not response on request “4.10 INFORMATION REQUEST (CODE 0x0A). Extended features supported 0х0002” and connection fails. According to Bluetooth specification the device have to response on such request with “INFORMATION RESPONSE (CODE 0x0B)”, however it does not.
Perhaps, the following is an addition to this issue: "Bluetooth - Windows 10 revision 1803 - SPP QOS regression"
Perhaps, the following is a confirmation of such issue: "Bluetooth Serial Port settings for Windows10 PC"
Is there any solution to fix this issue?
