ser2net with multiple software uarts

[miim]

Hello,
I would like to request to extend the option SER2NET plugin into the ESP-Easy firmware with multiple software uart.
Multiple software uart are available in arduino and have been ported to eps8266 here: softuart.h https://github.com/plieningerweb/esp8266-software-uart
SER2NET should provide one different TCP port per uart.

Application use case:
Connect several slow serial devices to an application server via ser2net.
I am using esp-easy with ser2net with one power meeter sending its status every second; I would like to connect the second power meeter to the same board.

---
A second improvement would be to allow 2 or more connection to the same ser2net port( nice to have)
benefit: multiple application server can share the same serial device

---
A third improvement would be to introduce a timeout for the tcp connection; after the timeout the port is closed.
benefit: Increased stability in case one application server loses the connection and reconnects.

Thanks in advance, I really appreciate your effort.
Best regards
miim

Dear all
I think I improved the robustness of the ser2net.
problem: If the client loses temporary the connection, the ser2net server is blocked and no reconnection possible, without a reboot.

Please consider adding following line to _P020_Ser2Net.ino after line 192

Code: Select all

 else ser2netClient.stop(); 

zipped patched file is enclosed below

best regards

Dear all
the change in release R99 has brocken _P020_Ser2Net.ino
- SaveTaskSettings(event->TaskIndex);
- LoadTaskSettings(event->TaskIndex);
reintroducing the 2 lines fixes the issue.

other topic:
I wrote a quick and dirty version of software uart: _P030_swser.ino
it can be combined with _P020_Ser2Net.ino and you have 2 serial interfaces connected to the network on 2 different ports
it is still very buggy; it requires a restart each time you change its setting.
you need the last version of https://github.com/plerup/espsoftwareserial
therefore in _P030_swser.ino you cannot configure everything: following is fixed
(8) data bits, no (N) parity bit, and one (1) stop bit


question for @ExpertDevelopers how and where shall I contribute? just post in the board or add some code proposal directly to git?
b.r.
