In order to control the device you need to determine the correct handles by quering the characteristics, e.g.

Note: The handles can be different. They relate on firmware and hardware version of your device

Characteristic value/descriptor: 56 4f 4c 43 46 54 04 00 00 00 00 01 0d 02 00 1e

+ Vendor string in ASCII (6 bytes)
If you have a device with hardware version 2 or lower you will get multiple notifications per request which depends on the type of request. If you have a device with hardware version 3 or above you MUST set the so called MTU so that the package size of notifications is set to 160 bytes. Then you get always just one notification per request.
