Acaia Pearl Scale not working

[marcuscozza]

Hi,

I have an Acaia Pearl Scale SN: AP0011401458 (PROCHBT001 00:1C:97:11:C4:0D) and i am trying to use this code to connect to my scale and tare it.

I am currently using windows 10 and trying to run the test.py code (After changing the mac address) initally when i run it, it comes up with an error saying that bleak.exc.BleakCharacteristicNotFoundError: Characteristic 49535343-8841-43f4-a8d4-ecbe34729bb3 was not found! So then i change it to the older style mentioned in the const.py file so it is 00002a80-0000-1000-8000-00805f9b34fb and it works with the following output but doesn't actual effect the scale in any way.

Writing stopTimer...
Writing bytearray(b'\xef\xdd\r\x00\x02\x00\x02')...
Writing resetTimer...
Writing bytearray(b'\xef\xdd\r\x00\x01\x00\x01')...

Just wondering what I can change to make it work and if you would have any idea what the issue is?

Thanks

I don't own a Pearl, so I have no idea unfortunately... You could try the original pyacaia library this is based on, to see if it make a difference.

Thats the thing I have been trying to get the pyacaia to work too but it doesn't and i tried this as you can use bleak on windows while pyacaia uses bluepy which is linux only. Which I did try on linux but get the same results of it not working. Just not sure if this scale is just too old and has a different encoding / decoding. Not sure what else you could recommand to try.
