Secure Connection with master using random static BDADDR

[wslkh]

Hi,

I am using a BLE master to bond with nRF52832. SDK is 15.3.0. Both side support secure connection.

I have tried to set the address type of master to public or random resolvable, and it works fine.

But when the master use random static address, when it try to reconnect and re-establish encryption after bonding, nRF52832 response with error code: PIN or Key Missing.

What's the problem?

Thanks.

Hi,

What is your BLE master? Is it a nRF device? Which softdevice are you using? Which example from the SDK are you using?

[wslkh]

Master: CC2564C with TI stack for STM32

Slave: nRF52832(PCA10040). SDK 15.3.0. S132 6.1.1

Could you give me more details on how you are testing?

Do you erase the bonding information on either of devices? Can you try deleting the bonding information on the master?
