NRF51 Bootloader Advertising Timeout

[erky]

Hi,

I am working on bootloader_secure example on SDK_12.1.0 and set APP_ADV_TIMEOUT_IN_SECONDS to 180 to stop the advertising after 3 mins.

All looks fine and device stops advertising 3 mins later but advertising LED still stays ON. Is there a way to make it OFF once the advertising stops?

I believe you might need to handler the BLE_GAP_EVT_TIMEOUT event inside the on_ble_evt function in nrf_ble_dfu.c file.

Add to the switch statement

case BLE_GAP_EVT_TIMEOUT: nrf_gpio_pin_set(ADVERTISING_LED_PIN_NO); break;

Or you can simply call advertising_stop function

case BLE_GAP_EVT_TIMEOUT: advertising_stop(); break;

Using advertising stop is probably the best method just in case there is clean up or flags to be cleared.

I recommend going for the second option, i.e. call advertising_stop() when you receive the BLE_GAP_EVT_TIMEOUT event.
