bounding with pc-ble-driver

[jpo38]

I'm using pc-ble-driver on Windows7 (from master as I'm using a s130v2 programmed dongle) to connect a BLE device (developer.nordicsemi.com/.../a00053.html).

This device supports bounding and I could find no example explaining how this should be handled using the pc-ble-driver API.

When I connect the "Nordic_Mouse" device, I receive BLE_GAP_EVT_CONNECTED event and BLE_GAP_EVT_DISCONNECTED right after it (with reason set to 0x3E, BLE_HCI_CONN_FAILED_TO_BE_ESTABLISHED).

How should I bound the device? What pc-ble-driver function should I use to bound the device as I do in the "Master Control Panel" when I click "Bound"?

Edit: With metch and Hung Bui help, I started trying to call sd_ble_gap_authenticate, like this:

ble_gap_sec_params_t params;
params.bond = (pairing != BTLE::Bound); // 1 to bond, 0 to pair?
params.mitm = 0;
params.lesc = 0;
params.keypress = 0;
params.io_caps = 1;
params.oob = 0;
params.min_key_size = 8;
params.max_key_size = 15;
params.kdist_own.enc = 1;
params.kdist_own.id = 1;
params.kdist_own.link = 1;
params.kdist_own.sign = 1;
params.kdist_peer.enc = 1;
params.kdist_peer.id = 1;
params.kdist_peer.link = 1;
params.kdist_peer.sign = 1;

uint32_t err_code = sd_ble_gap_authenticate(adapter, connectionHandle, &params );

However, this fails with code 6. Is there no working C-based example able to connect Dev kit programmed with "Nordic Mouse " example?

Hi jpo38,

To initialize bonding, you do it the same way you do as a central device, please have a look at our device_manager_central.c library.

You need to call sd_ble_gap_authenticate() to initialize bonding, store bonding information (the keys) and then call sd_ble_gap_encrypt() to re-encrypt the link based on the keys you stored.

Thanks for the reply, I'll look into that. Should sd_ble_gap_authenticate be called before or after device is connected?

To complete the @hungbui's answer, you should have a look at some sequences diagrams available here: infocenter.nordicsemi.com/index.jsp

For instance, the "GAP Central Bonding: Just Works" sequence chart (for S130 as central device) describes how to use the sd_ble_gap_authenticate function when the connection is established.

Thanks metch, @Jpo: Please follow the message sequence chart that metch pointed to.
