You would only be able to use passkey if the peer support keyboard, and one of the devices set MITM to 1

I'm sorry to trouble you again , I paste your code to project nrf6310\s110\ble_app_hrs,I found that it can connected without passkey. IO capability using BLE_GAP_IO_CAPS_DISPLAY_ONLY.Are there any specific withdrawal issues to be aware of?

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

Yes I had already downloaded s110 7.0.0, and using sdk6.0.0.Now, the propblem is when I using your Sample code it can't compile sucess.

Have you downloaded the S110 7.0.0 production files?

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.

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.

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 reply Morten, Now i can implement pairing as below, IO capability for both the end is set to keyboard only, then in the server side i hard-coded the passkey value to 123456, and added the below case in on_ble_evt,

case BLE_GAP_EVT_AUTH_KEY_REQUEST:
sd_ble_gap_auth_key_reply(m_conn_handle,BLE_GAP_AUTH_KEY_TYPE_PASSKEY, passkey);
break;

when i click bond in the master control panel it will ask for the passkey, and the passkey i need to enter is 123456. And also checked it is working fine.

But when i enter wrong key (121212) it is giving receiver link loss as i expected, but, in device info it is showing that Bonded: True and when i press bond button i am getting bond already exists with xxxxxxxx(device address). Please suggest me to overcome this.

Regards, Balaji

We don't have any sample applications for this, but the sequence of events and function calls needed are given here: Central OOB MSC

Beware however, that I'm not aware of any Central allowing the kind of low-level control you need to do this.

Thanks for the reply Morten, As you said, we can go for Numeric Comparison method, but i don't see any sample application with keyboard only IO capabilities, it will be more helpful for us, if we get sample application related to this.

See this answer, and possibly also the other ones in that thread.
