Pairing and Security

[HakJae]

Hi. I use the 'sdk 6' and 's110_nrf51822_7.1.0_softdevice'.

I would like to add security. I tried to passkey. If i enter passkey, it is possible to bond. but It is not required passkey, if i try to do pairing. In this case. when i do pairing, although I am not input the passkey, it is possible send/recieve command.

I want to do this. Only allowed device should be able to send/recieve command.

Do you have another way ?

Could you explain a bit more on how you have implemented this? Have you set attribute permission of the secure characteristic value with BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM()?
