Hello,

CONFIG_BT_SMP enables support for the Security Manager Protocol (SMP), so you can pair devices over LE. You can disable this configuration of you do not need to peer the device.

Usually, controller packet size needs to be 7 bytes larger than the amount of data we want to send for keeping place for a 4-byte L2CAP header and a 3-byte ATT header. This is the reason the BLE data length is 27, and the payload size is 20 bytes.

So, in order to notify 24 bytes , the length of CTRL DATA LENGTH should be 31.
