DS2502_DELLCHG example sends all data as FFs only

[arekm]

readme - it says to use 3.0.0 release but there is only 2.2.3 (which I'm using) available at that link. Arduino IDE 1.8.19

Describe the bug
Trying to run DS2502_DELLCHG example on Arduino Nano clone board. I'm checking if it works by using
https://github.com/KivApple/dell-charger-emulator/blob/master/dell-charger-data-editor.py script
and connection described at the end of https://github.com/KivApple/dell-charger-emulator page (but with additional 4.7k pullup resitstor; note: also tested without it)

With that script I'm able to read original dell charger eeprom just fine (doing that to confirm that wiring and script is ok).

Unfortunately with DS2502_DELLCHG I'm reading only FFs as data. So 1-wire seems to be working, just no correct data is sent.

To Reproduce

• get arduino Nano, upload DS2502_DELLCHG to Nano
• connect https://github.com/KivApple/dell-charger-emulator (end of the page) circuit to pin D2 on Nano
• execute python3 dell-charger-data-editor.py -> then option "8" to read data

Expected behavior

I would expect

charger130W = "DELL00AC130195067CN0CDF577243865Q27F2233\x9D\x72";

data to be read instead of 255s.

Logic analyzer shows:
reset condition, presence condition, skip rom command 204, data 240, data 0, data 0, and then only bunch of data 255

Screenshots

Dev-Environment:

• arduino nano clone with atmega328p
• arduino ide 1.8.19 on ubuntu linux
• for dell-charger-data-editor.py I'm using FT232R based USB serial adapter

And increasing ONEWIRE_TIME_MSG_HIGH_TIMEOUT to 35ms helper (which I thought is only meaningful if onewirehub is the receiving side).

Won't be that easy after all.

So ONEWIRE_TIME_MSG_HIGH_TIMEOUT is now set to 35ms. python script is able to read some data from emulated eprom:

On logic analyzer that reading is not even decoded (thing happening too slowly to be recognized as 1-wire?).

So connecting emulated charger to a dell laptop. It doesn't recognize the emulated eprom. Logic analyzer shows garbage on bus.

Any clues on what else I could try?
