Bonding Passkey Entry (Central display) or OOB

[steven]

hi,everyone. I try to use ble urat sample for bonding by passkey entry. and connection established and to bond. i try to entry passkey by uart. but when i key the passkey and go to service discovery . it can't work correctly. (see follow attachment file), can't send string ble to device.

how to i revise this ? is the service Characteristics need to do some thing? not go to ble_nus_on_ble_evt() BLE_GATTS_EVT_WRITE event,

2.what is O.O.B? how to use this?

code :

	
//init
#define SEC_PARAM_BOND                  1                                           /**< Perform bonding. */
#define SEC_PARAM_MITM                  1                                           /**< Man In The Middle protection not required. */
#define SEC_PARAM_IO_CAPABILITIES       BLE_GAP_IO_CAPS_KEYBOARD_ONLY  


//ble event handle			
case BLE_GAP_EVT_AUTH_KEY_REQUEST :
simple_uart_putstring("BLE_GAP_EVT_AUTH_KEY_REQUEST...\n");
while(iCount<6)
{
while (NRF_UART0->EVENTS_RXDRDY != 1)
{
// Wait for RXD data to be received
}							
NRF_UART0->EVENTS_RXDRDY = 0;
auth_key[iCount++]= (uint8_t)NRF_UART0->RXD;
}	
simple_uart_putstring("exit...\n");
err_code=sd_ble_gap_auth_key_reply(p_ble_evt->evt.gap_evt.conn_handle,BLE_GAP_AUTH_KEY_TYPE_PASSKEY ,auth_key);
APP_ERROR_CHECK(err_code);							
break;

At first glance your code looks OK, without more information it is hard to provide help.

2.what is O.O.B? how to use this?

OOB or Out Of Band is data transmitted over another physical link (think for example NFC) that serves as a shared secret between the two peers. If you are thinking of using a passkey (allowing the user to enter a 6-digit number) then you do not need to worry about OOB. Not many central devices support OOB today anyway.

hi,

i think that is interrupt priorities issue. when i try to disable the UART interrupt when the BLE_GAP_EVT_AUTH_KEY_REQUEST event. the program will be send to data to ble. but can't Receive data from RxD(because i have disable uart interrupt).

//ble event handle			
case BLE_GAP_EVT_AUTH_KEY_REQUEST :
simple_uart_putstring("BLE_GAP_EVT_AUTH_KEY_REQUEST...\n");
sd_nvic_DisableIRQ(UART0_IRQn);
while(iCount<6)
{
while (NRF_UART0->EVENTS_RXDRDY != 1)
{
// Wait for RXD data to be received
}							
NRF_UART0->EVENTS_RXDRDY = 0;
auth_key[iCount++]= (uint8_t)NRF_UART0->RXD;
}	
simple_uart_putstring("exit...\n");
err_code=sd_ble_gap_auth_key_reply(p_ble_evt->evt.gap_evt.conn_handle,BLE_GAP_AUTH_KEY_TYPE_PASSKEY ,auth_key);
APP_ERROR_CHECK(err_code);							
break;
