Hi GK, you can take a look at ble_app_gls example. it generate and pop out a random passkey everytime a mobile try to bond with device. no extra steps need.

Have you set that you want to bond, and that you require MITM protection?

#define SEC_PARAM_BOND                 1                                           /**< Perform bonding. */
#define SEC_PARAM_MITM                 1                                           /**< Man In The Middle protection required. */

Have you set the IO capabilites to display only?

#define SEC_PARAM_IO_CAPABILITIES      BLE_GAP_IO_CAPS_DISPLAY_ONLY                /**< Display I/O capabilities. */

Thanks for your answer, but it doesn't work in my application....

I added those code after ble_statck_init() in main, but my mobile phone still can pair nRF52832 without passkey.

What's wrong did I do?

You can try the ble_app_gls example in SDK 11.

Just add

uint8_t passkey[] = "123456";
ble_opt_t ble_opt;
ble_opt.gap_opt.passkey.p_passkey = &passkey[0];
err_code = sd_ble_opt_set(BLE_GAP_OPT_PASSKEY, &ble_opt);
APP_ERROR_CHECK(err_code);

somewhere after you have enabled the SoftDevice (ble_stack_init()). And it should work.
