Set Slave Address Command
Set the SHDLC slave address of the device.
.. note:: The slave address is stored in non-volatile memory of the
device and thus persists after a device reset. So the next
time connecting to the device, you have to use the new
address. When changing the address of a slave, make sure
there isn't already a slave with that address on the same
bus! In that case you would get communication issues which
can only be fixed by disconnecting one of the slaves.
:param int slave_address:
The new slave address. The address 255 is reserved for broadcasts.
