Hello,
I am using CYBLE-222014-01 for my project.
My customer is complaining about a pairing issue on Windows 10.
Security connection with Bluetooth devices became stronger on Windows 10 version 1903.
I was not able to pair more than one cypress units on Windows 10 of that version.
Their updates are like the below:
Addresses a security vulnerability by intentionally preventing connections between Windows and Bluetooth devices that are not secure and use well-known keys to encrypt connections, including security fobs.
and they suggest Contact your Bluetooth device manufacturer to determine if a device update exists.
Are there any updates about this on your side?
Thank you.
Solved! Go to Solution.

The version of BLE component I am using is 3.60.
I think the problem is because all the Bluetooth modules have the same Long term keys etc.
When I got the keys from CyBle_GapGetDevSecurityKeyInfo(), all the Bluetooth modules have the same long term keys like:
0xD6,0x93,0xE8,0xA4,0x23,0x55,0x48,0x99,0x1D,0x77,0x61,0xE6,0x63,0x2B,0x10,0x8E.
When I generate the keys from CyBle_GapGenerateKeys(0x03,&tlKeys), I got the keys like the below all the Bluetooth modules
0x7E,0x9A,0x27,0x8,0xD6,0x9E,0xB7,0x59,0xBF,0x29,0x30,0x5F,0x5,0x53,0x54,0x7E.
What are the keys generated based on?
Thank you.
