Get Settings and Set Settings variables

[mikeyin97]

Hello! Firstly, thanks for creating this repo, I have been working with the Ivy2 printer and this project has been immensely helpful, as it holds up well even 2 years later.

I just had a question about how to pass the color_id and auto_power_off in SetSettingTask in task.py? I am trying to change the auto power off time programmatically, and was wondering if you had figured out a way to do so.

I have attempted to process the response from GetSettingTask by adding a process_response, but it provides some binary items I am not sure how to interpret.

class GetSettingTask(BaseTask):
    ack = ACK_SETTING_ACCESSORY

    def get_message(self):
        return bytes(get_base_message(COMMAND_SETTING_ACCESSORY))

    def process_response(self, response):
      for i, item in enumerate(response[:2]):  
        print(f"Byte String {i+1}: {item.hex()}")

I would really appreciate if you could share any of your thoughts on this, and thanks again for building this repo!

Hey! Glad to hear its been helpful! For passing the color id and auto power off values, you should be able to use the printer's set_setting() method like follows:

    printer = Ivy2Printer()
    printer.connect(PRINTER_MAC)

    printer.set_setting(color_id, auto_power_off)

That said, I haven't been able to get any auto off values that I passed to stick. The printer will accept the values but still turns off after three minutes of inactivity. I did discover some enums for the color values but did not test them.

I opened #4 which adds those color enums as well as parsing for the get_setting() response. At the moment it only contains the current auto_power_off value as I didn't see any parsing of the color id from the printer.

I have been testing it a bit more (asked my advisor to check the Mini Print APK as well), and even though we haven't gotten it to work, we do note that the byte response from get_setting is in the following format

1 byte autoPowerOff
3 bytes firmwareVersion
1 byte skip
1 byte tmdVersion
2 bytes numberOfPhotoPrinted
1 byte colorID

Sample message:
03 - autoPowerOff
010407 - firmwareVersion
05 - skip
14 - tmdVersion
002c - numberOfPhotoPrinted
7f - colorID
0005010000000000000000000000000000

(mostly for reference for anyone else in the future)

Nice, that's good to know and would be worth implementing.

I snooped some packets earlier today where I changed the setting and it looks like the way setting messages are currently being built is incorrect. The auto off time is being passed immediately after the base message as an unsigned char.

Here it is being set to 5 minutes:

Then 10 minutes:

I'm kind of thinking color id may not be supported by the Ivy2. I couldn't find any mention of it in the manual or anywhere in the official app.
