I am having problems reading a value from a BLE characteristic after converting to Swift 3.

Before, using characteristic.value?.description with Swift 2.x, the value would return a String in hex format, ex: "<01>".

Now with Swift 3, the same code simple returns "1 bytes".

I have dug through SO for similar questions and answers but none speak of Data however it seems that it's not returning such an object.

Any help or insight is appreciated.

See e.g. https://stackoverflow.com/questions/39075043/how-to-convert-data-to-hex-string-in-swift for various methods to get the contents of a `Data` value as a hex-encoded string. – Martin R Jun 01 '17 at 18:56
