Add Check for lwIP version

[reaper7]

I am using a esp8266 arduino git version, in this case I do not get any error
because core_version.h contains ARDUINO_ESP8266_GIT_VER
maybe for users like me it would be good to add something similar

[arendst]

No need as the problems are solved in the git version where I suppose you talk about the stage version.

I tested Tasmota with the new lwIP 2.4.1 release and it works with no problem 👍 . I use lwIP v2 lower memory and the firmware is a bit smaller.

@arendst have you tested it?

[arendst]

Thnx for testing. Will do soon too.

[arendst]

Just provided version 2.4.1 boards.txt and platform.txt specific updates for tasmota.

I did some tests with 2.4.1 and regardless of lwip it just hungs after after some time ( under minute ). Maybe this is the cause : esp8266/Arduino#4497

[ascillato]

Interesting. I have my device working for hours without problem. Which tasmota version did you use and with which options? So as to try to reproduce that bug. Also how did you make the update? Serial / OTA? I used the serial with the arduino option to erase all the flash (just to try it). Did you build the firmware? Arduino / platform.io?

ESP-01 devices. Latest dev version. First OTA then serial. All the same. No bugs. Just hungs - stops working. Do you use webserver ?

[ascillato]

Yes. With webserver. But on a nodemcu El 12 mar. 2018 10:07, "Krzysztof" <[email protected]> escribió:

After downgrade to 2.4.0 (lwip 1.4) it is working fine.

Found it! 2.4.1 and Sleep >0 == hung.

[ascillato]

Great. I was not using sleep. Thats why. Very good job. Thanks El 16 mar. 2018 10:03 AM, "Krzysztof" <[email protected]> escribió:
