Hi , is there any example code to send the data directly from nrf5_SDK through BLE to app..??

[Reeshma]

can anyone please say..??

[Reeshma]

int main(void) { bool erase_bonds; // uint16_t err_code; static char PrintBuffer[40] = {0}; uint16_t length = 0 ; uint16_t counter = 0; uint32_t err_code;

// Initialize.
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_OP_QUEUE_SIZE, false);
uart_init();

buttons_leds_init(&erase_bonds);
ble_stack_init();
gap_params_init();
services_init();
advertising_init();
conn_params_init();

printf("\r\nUART Start!\r\n");
err_code = ble_advertising_start(BLE_ADV_MODE_FAST);
APP_ERROR_CHECK(err_code);

// Enter main loop.
for (;;)
{
    memset(PrintBuffer, 0x00, sizeof(PrintBuffer));
    sprintf(PrintBuffer, "Hello,%d\r\n",counter++);
    length = strlen(PrintBuffer);
    err_code = ble_nus_string_send(&m_nus, PrintBuffer, length);
     APP_ERROR_CHECK(err_code);
    nrf_delay_ms(100);
    power_manage();
}

}

i have tried the following code but it throws an error , when am compiling, am newbie to this platfrom ..can anyone please say..??

[Reeshma]
