Passkey activation

[Sascha]

Hello,

we try to use static passkey protection on our devices. we use nrf51 sdk12 with s130. We read a few threads for setting a static passkey like here, here and some other threads.. But we dont find any information or some routines for init and handle the passkey process, when connecting to a device. For example: where to put in the function sd_ble_opt_set() and where is the part in the code, where i can exactly activate the passkey is ON.

Our application: We want to connect with a smartphone as central to a peripheral nRF51 Hardware without display. This should be protected first with a static passkey we defined in main with the following code. We dont use MITM protection.

#define STATIC_PASSKEY        "111111"
uint8_t passkey[] =           STATIC_PASSKEY;

Most likely connection aborted due to reset at app_error_handler(). Can you run in debug mode and see where your code fails?

[Sascha]

It do not run into the app_error_handler(). Otherwise, we dont know a point to view at, where it could break up or check the key, we typed in.

First of all look at log of nRF Connect application. Also put break point at BLE_GAP_EVT_DISCONNECTED event and see what is in p_ble_evt->evt.gap_evt.params.disconnected.reason

[Sascha]

The reason: 0x13 BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION Direct after i press OK, when i typed in the key.

Maybe you can edit your question and upload your complete project so we can test it here? What SDK and SoftDevice version are you using?
