How to recognize the use of a 'WrongPasskey' ?

[nava_daniele93]

Good Afternoon,

I'm building a BLE application based on HW FRDM-KW36Z.

I want to detect with certainty the event of a disconnection caused by the use of a wrong passkey. 

I has been able to detect the following event:

pConnectionEvent->eventType = gConnEvtPairingComplete_c

pConnectionEvent->eventData.pairingCompleteEvent.pairingCompleteData.failReason == gSmPairingErrorConfirmValueFailed_c

This, apparently, is caused by the failure of the procedure of pin check.

This seems to be compliant with what i find in the BLE Core Specs 5.0. 

Can this event be generated by another cause?

Hello,

I'm not sure what you are trying to do, if the passkey you enter does not match it should not be able to perform a bonding. 

You can check the Wireless UART examples where the bonding and pairing it's being used.

Do you have a sniffer log of what you are referring to ?

Hi,

My setup is composed by a master KeyboardOnly and a slave DisplayOnly.

The application works correctly: if a wrong passkey is used, the connection is not performed. Following, i receive a Disconnect Event, with Cause: Connection terminated by remote user.

My issue is that I want to be sure that this disconnection event is caused by a wrong passkey.

I was able to recognize is the following event:

pConnectionEvent->eventType = gConnEvtPairingComplete_c

pConnectionEvent->eventData.pairingCompleteEvent.pairingCompleteData.failReason == gSmPairingErrorConfirmValueFailed_c

That i receive when a wrong passkey is used.

Hello,

So , just to confirm, did you solve your issue ?
