Hi,

Sorry for the very late reply. If you are stil struggling with this can you try to add NRF_LOG_FLUSH() after NRF_LOG_INFO() and see if that helps?

NRF_LOG_INFO("Passkey: %s", nrf_log_push(passkey));
NRF_LOG_FLUSH();

BR,

Marjeris

Thanks for the reply, I was in main.c do this.This code is normal, but when I only use LOG to print the pairing key, the key will not be printed during pairing. Uart does not have this problem.

case BLE_GAP_EVT_PASSKEY_DISPLAY:
{
char passkey[PASSKEY_LENGTH + 1];
memcpy(passkey, p_ble_evt->evt.gap_evt.params.passkey_display.passkey, PASSKEY_LENGTH);
passkey[PASSKEY_LENGTH] = 0;
// Don't send delayed Security Request if security procedure is already in progress.
err_code = app_timer_stop(m_sec_req_timer_id);
APP_ERROR_CHECK(err_code);
printf("Passkey:");
for(int i=0;i<6;i++)
{
printf("%c", p_ble_evt->evt.gap_evt.params.passkey_display.passkey[i]);
}
printf("\r\n");
NRF_LOG_INFO("Passkey: %s", nrf_log_push(passkey));
}break;

Hi,

Sorry for the late reply. Can you post the code you are using to print the pairing key? Are you doing this in main.c or in another file?

Best regards,

Marjeris
