Look in the Play store for a Bluetooth terminal app like nrfconnect and show what it finds when you try to talk to the device.

From where did you get that CharacteristicUUID?

I don't see any mention of it in the nrfConnect data stream.

The AI2 BLE extension has a block that can be used to ask for a list of Characteristics.
Maybe it would be informative?

ALso, if there are no Characteristics to support that sort of data flow, there is also the option of looking for Advertisement data from the device.
