CC1352R: BLE profile characteristic maxLen increasing

Lorenzo Venturelli
Intellectual 345 points

Part Number: CC1352R

Hello,

I'm writing an application using a custom board based on the SimpleLink CC1352R (Rev. E). I'm now writing my custom GATT Profile and I'm trying to implement the service's characteristics but I'm stuck in a problem with the maximum data length. I need to send a data structure that is 32 bytes long but apparently the max size allowed is 22 bytes, at least this is what I find inside the "maxLen" parameter when the profile Read Callback is called (after a characteristic read request from the client device).

Is it possible to send longer packets or should I break that data structure into two different parts?

Thank you in advance for your answers.

Lorenzo
