I'm sure that I've got the instance of a characteristic, but when I use the method getValue(),it return NULL.
Hi John, Please have a look at the description of readChactersitics()
You should wait for the onCharacteristicRead() and it's where you read the value out using getValue().
You can have a look at our example apps source code, to know how it work, for example the nRFUART app.
