Hi Nomi,

Have you tried this example?

Hi Nomi, I saw that in your code you didn't set any characteristic's permission to require encryption. All of them was set with BLE_GAP_CONN_SEC_MODE_SET_OPEN. The central device will not do bonding if they don't need to.

What you need to do is to set the read/write permission with encryption using MITM for the characteristics (so that passkey will be used) with BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM().

You can find this at line 118, 119 and 173 in the source code of the example here.
