Activate an LED via Bluetooth @ nRF51-DK, Linux, Python, gatttool, mbed

Dear Forum, I am new to BLE, but thanks to the great examples in the mBed compiler regarding the NRF51-DK I found a way to start.

What I'd like to do: Send a value to ble_device via char-write-cmd (I guess) and a simple if clause on the ble_device evaluates the value, in the most simple case: 001 = LED1, 002=LED2 and so on.

The thing is - I have no idea how to configure a UUID/handle which can be written on .... Could anybody give me some hints how to do this ?

Thank you so much ! ! ! Best, glycylalanin
