https://devzone.nordicsemi.com/f/nordic-q-a/12015/variable-length-notificationSometimes I only need to send 4 bytes instead of twenty using a notification. I&#39;ve noticed the init_len and max_len parameters but I&#39;m under the impression that this will not work for this purpose. I&#39;m trying to avoid sending the 16 extra bytes.
