saveNetwork and saveRegisters returns None

[AlexisTM]

Dear,

The functions local_device.saveNetwork and local_deviceRegisters are returning None instead of the POZYX_SUCCESS or POZYX_FAILURE.

With the current master a9cad47

While calling saveNetwork. The same saveRegisters Nonetype is now crashing the command.

Traceback (most recent call last):
  File "/home/alexis/scripts/setup_anchors.py", line 88, in <module>
    set_anchor_configuration()
  File "/home/alexis/scripts/setup_anchors.py", line 63, in set_anchor_configuration
    pozyx.saveNetwork(remote_id=tag)
  File "/usr/local/lib/python2.7/dist-packages/pypozyx/lib.py", line 1515, in saveNetwork
    status &= self.saveRegisters([POZYX_POS_NUM_ANCHORS], remote_id=remote_id)
TypeError: unsupported operand type(s) for &=: 'int' and 'NoneType'

Solved by replacing:

    def saveRegisters(self, registers, remote_id=None):
        """
        Saves the given registers to the Pozyx's flash memory, if these are writable registers.

        This means that upon reset, the Pozyx will use these saved values instead of the default values.
        This is especially practical when changing UWB settings of an entire network, making it unnecessary
        to re - set these when resetting or repowering a device.

        DISCLAIMER: Make sure to not abuse this function in your code, as the flash memory only has a finite
        number of writecycles available, adhere to the Arduino's mentality in using flash memory.

        Args:
            registers: Registers to save to the flash memory. Data([register1, register2, ...]) or [register1, register2, ...]
                These registers have to be writable. Saving the UWB gain is currently not working.

        Kwargs:
            remote_id: Remote Pozyx ID.

        Returns:
            POZYX_SUCCESS, POZYX_FAILURE, POZYX_TIMEOUT
        """
        self.saveConfiguration(
            POZYX_FLASH_REGS, registers, remote_id)

Hey Alexis,

Sorry for the long wait! I'm working with the Python library this week so I'll be catching up on maintenance and put a new version on PyPi

[laurentva]

Fixed in develop, will merge into master and release after testing

[AlexisTM]

Thanks
