Hi Peter,

thank you for reporting this and also sorry for difficulties. They made some major changes between version 5 and 6 of ArduinoJson library.

I upgraded the Arduino sketch - see attached one. It can be compiled now however I don't have any ESP8266 around so didn't make any further tests.

Let me know about your progress.

Regards, Tomas

Hi Peter,
you can use the MP block for such a purpose. Set the MP:pwidth parameter to e.g. 5 seconds and set the MP:RPTF parameter to ON.

From your ESP32, you'll periodically write ON to MP:BSTATE parameter (e.g. once per second) via REST API of REXYGEN. As long as the ESP32 keeps communicating, the output MP:Y will be ON. If there is no communication from ESP32 for more than 5 seconds, the MP:Y output will turn OFF.

In other words, the MP block acts as a communication watchdog in this case.

Hope it helps, let me know.

Kind regards,
Jaroslav

Hi Geocipo,

thanks for asking. You can send HTTP commands (HTTP GET and HTTP POST) using HTTP2 function block. Have a look at "0302 IoT Integrations" example folder where you can find many examples with HTTP2 function block in various situations.

If you need more information, let me know.

Tomas

ok thanks for the answer, i will try.

Hi George,

we have no specific example on using REXYGEN REST API in C# .NET at the moment. However there is an example with scripts in Python, Bash or Matlab available - see Example 0302-03 REST API Python Bash etc.

Let us know if it helped to solve your issue.

Regards,
Tomas
