Respected sir,
There is added external reset button at SRU532 module, and changes are given according to it using wakeup button at code.When wakeup button is used then some part is uncommented and want to reset only one pin using one button of nRF51422.It is done for reset time of BLE advertising after 3 min or within 1 hr,but it is not worked.How it will solve?
...
Hi,
Please refer for instance to the \examples\ble_peripheral\ble_app_hids_keyboard on how to achieve this:
[...]
uint32_t bsp_btn_ble_sleep_mode_prepare(void)
{
uint32_t err_code = bsp_wakeup_button_enable(BTN_ID_WAKEUP);
RETURN_ON_ERROR_NOT_NOT_SUPPORTED(err_code);
err_code = bsp_wakeup_button_enable(BTN_ID_WAKEUP_BOND_DELETE);
RETURN_ON_ERROR_NOT_NOT_SUPPORTED(err_code);
return NRF_SUCCESS;
}
[...]
static void sleep_mode_enter(void)
{
uint32_t err_code = bsp_indication_set(BSP_INDICATE_IDLE);
APP_ERROR_CHECK(err_code);
// Prepare wakeup buttons.
err_code = bsp_btn_ble_sleep_mode_prepare();
APP_ERROR_CHECK(err_code);
// Go to system-off mode (this function will not return; wakeup will cause a reset).
err_code = sd_power_system_off();
APP_ERROR_CHECK(err_code);
}
[...]
sleep_mode_enter();
while(1);
[...]Thanks for it.I want one button used for reset BLE advertising time which is by default 180 sec in given code.Here used SRU532 module,SDK 9.0 and softdevice s310 for nRF51422.How one pin of SRU532 module is configured from software as well as hardware side?

Want to use one button from it,how can I use it at hardware as well as in software?
There is an old tutorial on board support package, maybe you can take a look at it:
https://devzone.nordicsemi.com/tutorials/b/software-development-kit/posts/board-support-package-bsp
Thank you for response.I want only one button in use #define BUTTON_A 23 for reset #define APP_ADV_TIMEOUT_IN_SECONDS 180, this time.Then what exact changes are require to do that?
The easiest may just be to have a global variable that you set on button press, and when advertisement time-out (BLE_ADV_EVT_IDLE event), then check if the global variable is set, and if set then clear global variable and start advertisement again.
