Variable Length Characteristic with Notification

[WestCoastDaz]

How do I set up a variable length characteristic which is greater than 20 bytes and use notifications with this characteristic?

For example I have several variable length characteristics which are greater than 20 bytes and the goal is these would be read with a long read on the GATT client after the connection was established. Then notifications would be turned on for this characteristic and the data transmitted would <= 20 bytes.

Thanks

Don't really understand the question. You make a characteristic as long as you like, variable length if you want, just as usual, and you notify up to the first 20 bytes of it during a notification, as usual, and if the client wants the rest of it they do another long read to get the rest of it, as usual.

This is a standard use case for a characteristic.

RK, thanks for the clarification.
