Esp32 with Arduino to Signal K
#1
Hello to all,

I'm jsut seting up my 1st esp32, is really interesting what you can do!

I've the following problem is to send form Esp32 with Arduino to Signal K.

I know to program in C, so is quite close to Arduino.

I'm taking information from:

https://randomnerdtutorials.com/esp32-ht...t-arduino/

And of course manual Singal K:
https://signalk.org/specification/1.7.0/...ction.html



My problem is to learn how to connect esp32 "logining into the server", "sending data json", and so on, as they I guess are special functions and protocol, that I could not find in the last two sites.

Someone knows about a tutorial, or a simple example Arduino code to see and undestand how it works?

Thanks a lot!!!

I've gone over to micropython on the Esp which I much prefer, but for C there might be some useful routines from back in the day in here>>

Vague memories of the json library needing to be an older version than current.

Have you looked into SensESP:

https://signalk.org/SensESP/pages/getting_started/ 

there are likely some code snippets and libraries you can use to get stuff into SignalK, or in fact use the templates and build from their

I have been building a engine data gatherer as has @Boatingbaileys who did a YT video on it

Thanks a lot to all of you. I will do different trials druing this weekend, Also I found a web site really interesting, and if I'm not wrong, is from a member of this forum.
