CY5677 dongle does not connect with peripheral after bonding
I have a question regarding the CY5677 BLE4.2 dongle.
I use the example BLE4.2 project with the following configuration.
Security mode: 1
Security level: Unauthenticated pairing with encryption
I/O capabilities: No input/no output
Bonding requirement: Bonding
Link Layer Privacy disabled
The CY5677 BLE4.2 dongle is connected with the peripheral (CY8CKIT-143A pluged to the pioneer BLE kit) and it succesfully enables the notifications using the CySmart 1.2.
The problem is when I try to reconnect. In the pairing procedure, the error "Authentication failed. Value information mismatch" is displayed.
Applying the exact scenario using the dongle BLE4.1, this error is not noticed.
Why this error fires? Is perhaps a bug in dongle firmware or CySmart or am I doing something wrong?
