I think, that it will be better if the installer has an option to specify an path where the devkik will be installed.

This is problematic because the path C:\Espressif hardcoded in the utilities esptool.py, gen_appbin.py and gen_appbin_old.py

I noticed that the measurement time has an effect on lwIP

reset();
select(addr);
write(DS1820_CONVERT_T, 1); // perform temperature conversion
sleepms(1200);
................
and log:
DNS found, host: 184.106.153.149, address: 184.106.153.149
TCP created.
RECONNECT
Connection error: -11 - Not connected
os_free: conn->proto.tcp
os_free: conn

DS18B20 needs a minimum of 750 ms per measurement.
According to my tests if the time is greater than 1 s (in example we have 1 s), it affects the operation of lwIP.
(perhaps interferes also with smaller time ???)

So I have a question: how long can the timer thread be?
What is the priority of this timer?
