https://devzone.nordicsemi.com/f/nordic-q-a/18696/nrf51-bootloader-advertising-timeoutHi, 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.
