SDK11 S130 BLE Disconnect

[yzfy_12345]

HI:

      I Select the SDK11 as my BLE master.  

                           " nRF5_SDK_11.0.0_89a8197 \ examples \ ble_central \ ble_app_multilink_central \ pca10028 \ s130\arm5_no_packs ".

     I Select the Test board as my BLE master:   PCA10028 v1.2.0      2016.15     681374555

     softdevice: S130

      my probem:   

               My BLE master  can  connect with my ble slave ; this is OK.

               But, when My BLE Slave power cut off;  or restart,  the BLE Master will restart, too.    why???

 

thank you!

Hi,

It may look like you are experiencing an assert on the master here, by default the application is setup to run NVIC_SystemReset() on assert, however if you set DEBUG then you can set a breakpoint in app_error_fault_handler() or app_error_save_and_stop() to find identify error code, line number and file name causing the assert.

Best regards,
Kenneth

Thank you for your apply. Now, I have a new problem.

My MCU: nRF51822-QFAA

I Select the SDK9 as my BLE slave:  nRF51_SDK_9.0.0_2e23562\examples\ble_peripheral\ble_app_template\pca10028\s110

Phenomenon of problem：

        When my BLE Slave device connect success, My BLE Master will send data to slave.

        When receive the data, My salve device will  active disconnect。Call this function: "My_BLE_Disconnect_Fun()"

//====================================================

void My_BLE_Disconnect_Fun(void)
{
uint32_t err_code;

if(My_Service.conn_handle == BLE_CONN_HANDLE_INVALID)
{ return; }

err_code = sd_ble_gap_disconnect(My_Service.conn_handle, BLE_HCI_CONN_INTERVAL_UNACCEPTABLE);
APP_ERROR_CHECK(err_code);
}

//====================================================

int main(void)
{
uint32_t err_code;
bool erase_bonds;

// Initialize.
timers_init();
buttons_leds_init(&erase_bonds);
ble_stack_init();
device_manager_init(erase_bonds);
gap_params_init();
advertising_init();
services_init();
conn_params_init();

// Start execution.
application_timers_start();
err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
APP_ERROR_CHECK(err_code);

// Enter main loop.
for (;;)
{

if(BLE_Rx_OK)
{
    BLE_Rx_OK = false;
    if(OOL_Up_Fg == false)
    {
        BLE_Rx_Function();
    }
 }

  power_manage();
}
}

//=============================================

I  test discovery:

       When I call the function "My_BLE_Disconnect_Fun()"， Sometimes it  restarts and sometimes the normal.

       Why ?? what  caused the restart???

Thank you very much!

Likely one of the function calls return an err_code, this will trigger the assert_nrf_callback() -handler to execute, it may be setup to do a system reset(). You should check the assert_nrf_callback() for line number and error code.
