Need some help using BLE_GAP_CONN_SEC_MODE_SET_LESC_ENC_WITH_MITM.

[BenBurch]

Hi!

Is there an example of how to use BLE_GAP_CONN_SEC_SET_MODE_LESC_WITH_MITM?

I cannot find one and I am having a hard time understanding what I need to do to make this work.

My scenario is this;  We have a passkey provided by a second processor to the 52840, and also displayed on a display by that processor. My code will set that as the passkey and the user will go to the external gateway screen and enter that same passkey, following which passkey will be saved and used every time the system connects.

Examples would get greatly appreciated.

Hi,

I believe the follwing example do this:
https://infocenter.nordicsemi.com/topic/sdk_nrf5_v16.0.0/ble_sdk_app_multirole_lesc.html 
\nRF5_SDK_16.0.0_98a08e2\examples\ble_central_and_peripheral\experimental\ble_app_multirole_lesc

It is not using passkey, but numeric comparison, but give the same level of security (LESC with MITM).

If you want to know the details (e.g. and how to change from numeric comparison to passkey) you can check out the documentation:
