Convert Java.Byte.Array to "normal" Arrays to send Binary Data via Cirrus Link MQTT

[justin.brzozoski]

You may need a special hammer to fit an arbitrary Python byte string into a jarray that writeFile likes:

[IGN-4991, IGN-4996]system.file.writeFile encoding

Once I decided the built in ways were broken, I just built a bigger hammer: def pythonByteString_to_jarray(pyString): return jarray.array(((x if x < 128 else (x - 256)) for x in bytearray(pyString)),'b')
