modification python files for serial mesh example

[Sama]

Hi,

I am using sdk for mesh V.5 and nrf52840 dk.

I have run the serial mesh example and it worked fine.

I also modified the light switch example to send and receive string data through the mesh.

How can I modify the python files of the serial mesh to the config client as I changed in the c.files?

Thank you in advance.

Hi Sama, 

Could you please elaborate more exactly what you want to do with "How can I modify the python files of the serial mesh to the config client as I changed in the c.files?" ? 

Which python files are you asking about ? Is it the PyACI example we have ?
Which modification you added to the light switch example ?

Hi Hung,

Thank you for your reply and I am sorry for my late reply.

I have modified the light switch example to send string data through the mesh and added several peripherals as well. 

Regarding python files, I mean PyACI example. As far as I found out, the "interactive_pyaci" folder contains python files used for provisioning and configuration of client and server. Furthermore, there is a folder named "model" which includes the generic and simple on-off models. 

My question is that, regarding modifications I did, how can I use this example?

Is there any solution to report the hex files of my codes to python?

Br,

Hi Sama, 
I don't know what you modified in your light switch example so it's hard to give you any advice. 

But if you have a look at the simple_on_off.py model, it's not too hard to understand: 

class SimpleOnOffClient(Model):
    SIMPLE_ON_OFF_STATUS = Opcode(0xc4, 0x59, "Simple OnOff Status")
    SIMPLE_ON_OFF_SET = Opcode(0xc1, 0x59, "Simple OnOff Set")
    SIMPLE_ON_OFF_GET = Opcode(0xc2, 0x59, "Simple OnOff Get")
    SIMPLE_ON_OFF_SET_UNACKNOWLEDGED = Opcode(0xc3, 0x59, "Simple OnOff Set Unacknowledged")

    def __init__(self):
        self.opcodes = [
            (self.SIMPLE_ON_OFF_STATUS, self.__simple_on_off_status_handler)]
        self.__tid = 0
        super(SimpleOnOffClient, self).__init__(self.opcodes)

    def set(self, state):
        message = bytearray()
        message += struct.pack("<BB", int(state), self._tid)
        self.send(self.SIMPLE_ON_OFF_SET, message)

    def get(self):
        self.send(self.SIMPLE_ON_OFF_GET)

    def unacknowledged_set(self, state):
        message = bytearray()
        message += struct.pack("<BB", int(state), self._tid)
        self.send(self.SIMPLE_ON_OFF_SET_UNACKNOWLEDGED, message)

    @property
    def _tid(self):
        tid = self.__tid
        self.__tid += 1
        if self.__tid >= 255:
            self.__tid = 0
        return tid

    def __simple_on_off_status_handler(self, opcode, message):
        on_off = "on" if message.data[0] > 0 else "off"
        self.logger.info("Present value is %s", on_off)

In this case it's only one byte payload when you send a SIMPLE_ON_OFF_SET_UNACKNOWLEDGED. ( int state)

In your case you may want to send varied length string, you may want to have a look here.
When you receive a message from the server, you will need to print the message inside __simple_on_off_status_handler()

Hi Hung,

Thank you very much for your support.

I should add some modifications in my code and that has been not completed yet.

So once it is completed, I will send my codes to you.
