peripage-a6-bluetooth's Issues

Reverse engineering questions

I'd suggest to add a variable delay in the sending loop so printer will have enough time to print each part of received chunk without hanging

time.sleep(0.05)

In addition Android/ios application should be reverse engineered for more detailed protocol description, variable width printing, e.t.c, but they're obfuscated and shitcoded

I have discovered that the hex sequence {10 FF 10 00 xx} is the command to set the print darkness. Observed the app using values of 0, 2, or 4; intermediate values seem to work as well. Higher values don't seem to fail, but are not visibly different from 4.

You could add this as a feature, if you like... :)

EDIT:
It seems this command doesn't take effect until after the 12 null sequence is sent. (At least on the A9 I'm testing with. This script fully works with the A9 as far as I have tested. If you wanted to add more support for it, A9 print width is 0x48, 576 dots)

Why is that? should the image be saved somewhere specific?

Error building pybluez

I have Python 3.10.2 on Windows. Do you have a suggestion why the package pybluez doesn't work?

Implement script command to change serial number

@bitrate16 figured out that the S/N can be changed via a command:

Using the poke method i've found out that it has additional configuration commands, but now i've lost ability to print text and get S/N

UPD: S/N break code 10ff20f4
UPD2: Write [0x10ff20f4, 'S/N'] will overwrite S/N with new value 'S/N'. String has to be terminated with '\0'
UPD3: 10ffff** configures print modes
UPD4: I don't understand it, sending any raw string makes printer print it

_Originally posted by @bitrate16 in https://github.com/eliasweingaertner/peripage-A6-bluetooth/issues/1#issuecomment-803662260_

Goal of this issue to make this functionality available from the script.
