How to implement the static PIN type pairing?

[balaji]

Hi, How to implement the static PIN type pairing, when the server device doesn't have keyboard or display? Our requirement is, Master will initiate the pairing process and device should ask for the PIN (6 digit static), when master enters the correct PIN then the connection should be established between the device and the master. Is there any sample application for server with keyboard only IO capability?

With the latest softdevice www.nordicsemi.com/.../S110-SoftDevice-v7.0 you will be able to set a static passkey.

By using the API call sd_ble_opt_set() with the structure ble_gap_opt_passkey_t, then the passkey display event will come with the passkey you set.

Code Sample:

uint8_t passkey[] = "123456";
ble_opt_t ble_opt;
ble_opt.gap.passkey.p_passkey = &passkey[0];
(void) sd_ble_opt_set(BLE_GAP_OPT_PASSKEY, &ble_opt);

Use IO capability display in the sec params request.

Thanks for the suggestion Pal, What is option ID? where can i get this? any sample code regarding this? a simple code snippet will help me a lot.

Hi Pal,

Thank you for your suggestion. I tested the sample code,it can't compile.The compile error is the ble_opt_passkey_t undefine.

Have you downloaded the S110 7.0.0 production files?

Sorry about that, I had some problems in my code, I wrote it from the top of my head, without testing it. Updated in response
