Into int_handler() at the top.

Btree is included now. You should have it in the daily build tomorrow.

after 'wlan.connect('ssid', 'password')' the connection does not happen immediately. You have to wait until the device is connected, checking with wlan.isconnected(). You can set the ip address before calling wlan.connect(). Then that one is used right from the start. P.S.: That's the script I use a...

The btree module is about to be included again for the ESP32. Damien is working on it.

Update the Firmware to the newest daily build. The read() is non-blocking.

Everything is fine. Just the way LED is connected, led.value(0) switched the led ON, led.value(1) switches it OFF.

Assuming you have the common anode at 3.3V it should work. Two notes: - led.on() and led.off() are confusing API names, since led.on() switches the output to high level, and led.off() to low level. So led.off() should switch the led on, and the opposite. But it should switch. I prefer to specify the...

People here are not very good at remote mind reading, so we need more technical details.
Please tell us,

- which RGB led you are use
- how you connected it to the ESP32 board and
- which python commands you used.

That's interesting. You still need the circuitry to make the TX pin open drain.
For access to the board you would need something like pyserial. I found that link: https://pypi.org/project/micropython-serial/, but could not get it working instantly.

Is this possible? No, it's not. The UART protocol and the DS18B20 protocol are completely different. UART uses a character tieming with start bit/5-9 data bits and stop bit, and deidcated input and output mode lines, while Onewire uses a single data line for both input and output, a bit timing swit...
