We have an example on GitHub with static passkey, please see this.

This MSC from our SDK documentation might also be of help.

Hi, I am facing some problem in device manager initialization for static passkey implementation. I have added "device_manager_init()",device_manager_evt_handler(),sec_req_timeout_handler() functions to implement device manager functionality. device_manager_init() is just called after ble_stack_init() function in ble_evt_dispatch() function, I have added dm_ble_evt_handler() in timers_init() new timer is created for Security Request.

dm_ble_evt_handler() is added ble_evt_dispatch() to take device manager functionality into account. in on_ble_evt() added BLE_GAP_EVT_PASSKEY_DISPLAY case,

I have observed that sd_ble_gap_authenticate() , which is called dm_security_setup_req() is returning "NRF_ERROR_INVALID_STATE". I have checked all input arguments of dm_security_setup_req(), and proper. could someone help me to found , where I am doing mistake.

Regards, Raju

Hi Raju,

It looks like the attachment is missing.

But I understand you are trying to make the device manager module handle security. But have you registered with device manager with the right security parameters (using dm_register)? For your case, you will need to turn on mitm when you register with dm_register. But I dont see you doing this in step 5.

If you do not want to use device manager, then undo what you did in step 3 (keep the case you added for BLE_GAP_EVT_PASSKEY_DISPLAY), step 4, step 5, and step 6. It should work as per your expectation.

Cheers, Balaji
