How to decode:
dbus.Array([dbus.Byte(1), dbus.Byte(35)], signature=dbus.Signature('y'))
to HEX or String in Python code.
Maybe what you want to do is to convert it to bytes; below you can see how I used to write it to a binary file.
localFile = open ('/home/youruser/data.bin', 'wb')
try:
for byteValue in arrayValue:
localFile.write(chr(byteValue))
finally:
localFile.close()
