BLE device not discoverable to Nordic apps [nRF51822]

[vineeshvs]

Dear all,

I tried the example program ble_app_uart given in the examples section of the Nordic folder in Keil installation. I created the hex code and programmed my chip. But the device is not discovered by the Nordic apps (nRF master control, nRF toolbox etc).

I don't have a beacon or development board. I am programming the board purchased from here using a segger board.

---

Given below is the main() of the main.c function in the ble_app_uart project

int main(void) {
int j;
uint8_t start_string[] = START_STRING;
uint32_t err_code;

// Initialize.
APP_TIMER_INIT(APP_TIMER_PRESCALER, APP_TIMER_MAX_TIMERS,   APP_TIMER_OP_QUEUE_SIZE, false);
APP_GPIOTE_INIT(APP_GPIOTE_MAX_USERS);
ble_stack_init();
uart_init();
err_code = bsp_init(BSP_INIT_LED | BSP_INIT_BUTTONS,
                    APP_TIMER_TICKS(100, APP_TIMER_PRESCALER),
                    NULL);
APP_ERROR_CHECK(err_code);
err_code = bsp_buttons_enable(1 << WAKEUP_BUTTON_ID);
APP_ERROR_CHECK(err_code);
gap_params_init();
services_init();
advertising_init();
conn_params_init();
sec_params_init();
			
printf("%s",start_string);

advertising_start();

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

Shall I post the full program (Not doing now, since its too big)

Thanks

Did you also flash the Soft Device?

[vineeshvs]

First I loaded the hex file for flash device before programming with the hex file which contains my application.

[vineeshvs]

BLE is detected in BLE scanner app.

Its not from Nordic though

[Inspectron]

Yes, but what is with the SoftDevice? You need to flash the softdevice if you want to use BLE applications

This is strange, nordic application should be detected by nordic tools (especially when they are detected by external tools)

Have you made any changes to the default example? Which SDK and softdevice version did you use? Also which nordic tools did you use? is it android or IOS?
