nRF52840 Enable Pairing with Static Passkey

[Muqarrab]

Hi,

I am working on the ble_app_template project.

1-How can I enable simple pairing without NFC?
2-Also how can I set pairing code?
3-Is the write way to secure characteristics?

    attr_md.rd_auth    = 1;
    attr_md.wr_auth    = 1;

 

Thanks!

Hi Muqarrab, 

Please see the Security parameters documentation for pairing and this post for secure characteristics.

Can we perform Just Works bonding(without entering any key) without NFC Antenna?

[Amanda Hsieh]

Yes, many of the BLE examples in the SDK uses Just Works with pairing/bonding, e.g. the ble_app_hrs example. As seen here, the Device/Peer Manager is configured as this when using "Just Works bonding":

sec_param.bond = true;
sec_param.mitm = false;
sec_param.lesc = 0;
sec_param.keypress = 0;
sec_param.io_caps = BLE_GAP_IO_CAPS_NONE;
sec_param.oob = false;
sec_param.min_key_size = 7;
sec_param.max_key_size = 16;
sec_param.kdist_own.enc = 1;
sec_param.kdist_own.id = 1;
sec_param.kdist_peer.enc = 1;
sec_param.kdist_peer.id = 1;

Is it possible without NFC Antenna?

[Amanda Hsieh]

yes, the ble_app_hrs example is without the NFC Antenna.

I have uploaded the ble_app_hrs example and connected from the nRF app.
But I have not received/got pop up for pairing?

[Amanda Hsieh]

It won't pop up for pairing. You have to perform pairing as the Heart Rate Application documentation.

Hi Amanda Hsieh

I have to question.

1-If I made authentic/secured characteristics. Can I read/write data using this pairing method? Is this pairing method secure?
2-How can I get a paring request like this in the attached image? Any example code?




Thanks

If you want to test that pairing is required but not Man In The Middle (MITM) protection, then I would suggest you try BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM() instead.
