I have asked @rtek1000 @overisberg as it was working for him before.

someone still need to write this feature into esp-link source, on the other hand it is not good idea to connect to host in the internet, so it should be...

You mean connection on port 23? Are you sure esp—link breaks connection - not other side?

why?

can you find a way to reproduce this problem? provide flash dump with it I can try to investigate it further

yes, but first need to manage a little bit of spare time for this, thanks for dumps will try to test

uno wifi rev1 have special IC for communication, so you should setup it first  [schematics](https://raw.githubusercontent.com/wiki/jandrassy/UnoWiFiDevEdSerial1/files/Arduino-UNO-WiFi-V4_AF1.pdf) You need to somehow pull up/down GPIO4 on ESP module [hints here+wiki](https://github.com/jandrassy/UnoWiFiDevEdSerial1)

try with latest version : [esp-link-v3.2.47.alpha.5-ga0d3bb3-dirty-Lucjan3.tgz.zip](https://github.com/jeelabs/esp-link/files/3378972/esp-link-v3.2.47.alpha.5-ga0d3bb3-dirty-Lucjan3.tgz.zip)

try to flash with options: --flash_freq 40m --flash_mode dio

what is in logs after this part: ``` 335> ** esp-link v2.2.3 - 2016-06-21 21:58:48 - 1bcdc62: ready, heap=25112 342> initializing user application 346> Waiting for work to do... 349>...
