Sets the optional characteristic presentation format descriptor. This is
not required for most characteristics, but may be required by certain
adopted characteristics or by a custom use case. For integer value
formats, the actual value is equal to storedValue*(10^valueExponent)
ble.setLogLevel(&bleChar, valueFormat);
ble.setLogLevel(&bleChar, valueFormat, valueExponent);
&bleChar: A pointer to a BLE_Char.
valueFormat: An unsigned integer specifying the data type of the characteristic value. Here is a list from the official Bluetooth SIG website.
valueExponent: A signed 8 bit integer only required for integer value formats.
