Can you please let me know what is the BLE component version you are using in the PSoC Creator?
Can you please change to latest version BLE v3.60 component (In psoc creator, Goto->Project->Update components) and check.
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:
When I generate the keys from CyBle_GapGenerateKeys(0x03,&tlKeys), I got the keys like the below all the Bluetooth modules
What are the keys generated based on?
