https://devzone.nordicsemi.com/f/nordic-q-a/6393/how-to-implement-gatts-characteristic-broadcastHi, I try to make characteristic broadcasting through advertisement data packets. Added these codes below, but no yet work.

The peer can enable and disable them, but once enabled the app still needs to call sd_ble_gatts_hvx() it&#39;s not done automatically by the stack.</p><div style="clear:both;"></div>
