Hello,I am developing a Bluetooth peripheral that will use advertising extensions to broadcast expanded information in the advertising payload. I noticed in the WWDC '19 talk that Core Bluetooth will support advertising extensions with sizes up to 124 bytes. However, the specification supports advertising extensions up to 255 bytes per message (this is even shown on the first three slides for the talk where the advertising extension payload is described). We plan to use the full 255 byte payload for our peripheral if possible. My question, then, is what the expected behavior of Core Bluetooth is when it finds advertising extension data longer than 124 bytes - does it truncate the received message to 124 bytes, discard the data entirely, or some other behavior? This will inform how we design the data format we're using.Thank you in advance for any information!
