required Bluetooth ON and OFF functions in "ble_app_uart" example

[Thiru]

Hi,

I want to write Bluetooth ON and OFF functions for the project purpose,

what are all the steps needs to follow while creating ON function and same for OFF function.

Thanks in advance

Kind Regards,

Thiru.

Define two command "BT ON"&"BT OFF"

if client get nus_data_handler()

static void nus_data_handler(ble_nus_evt_t * p_evt)
{

char* str_cmp;

if (p_evt->type == BLE_NUS_EVT_RX_DATA)
{
uint32_t err_code;

NRF_LOG_DEBUG("Received data from BLE NUS. Writing data on UART.");
NRF_LOG_HEXDUMP_DEBUG(p_evt->params.rx_data.p_data, p_evt->params.rx_data.length);

 str_cmp =strstr(p_evt->params.rx_data.p_data,""BT ON");

 if (str_cmp!=NULL)   do_on_func();

str_cmp =strstr(p_evt->params.rx_data.p_data,""BT OFF");

if (str_cmp!=NULL)   do_off_func();

}

}

What i mean is,

I need function definition for bluetooth ON and OFF functionality.

Thank you.

You can start and stop advertisement, or you disconnect the connection if you are already connected. There is api that can handle this:

You may then enter system off state to save current, for instance while waiting for the user to press a button to wakeup the device again.

HI Kenneth,

Thank you for the reply,

sd_ble_gap_disconnect(m_conn_handle, BLE_GAP_EVT_ADV_SET_TERMINATED);
sd_ble_gap_adv_stop(m_advertising.adv_handle);

I have tried both calls, but the bluetooth discovery is not stoped

Need to follow any sequence?

Thank you for the support.

What is the return code for those two calls? Also, it may be that the application is setup in a BLE callback that when the link is disconnected, that the application should start advertisement again, so look for that.

Best regards,
Kenneth
