How to import data from wifi into arduino?

[memoric77]

Hi Community,

I want to use the incoming UDP-data over WIFI via the ESP8266 Modul to use it for my WIP ButtbonBoxV3. Who knows and want to share how it could work? We could use it to turn a indicator on/off if a car is beside us, control a stepper motor for analog rpm display, turn on led for different race flags, display gear oder rmp for example.

I´am new in Arduino and C+ and never used the ESP8266 Modul, but it could´nt be so hard to do and maybe a clever guy could write up the Sketch within a minute . IMHO it has to be the same like reading the UDP data into an App like actually PCars Dash or CrewChief, but in this case via Arduino: "If serial data from UDP wifi is "blue flag" -> turn on blue led" ...

Who wants to be the first to answer??

Continued from vrHive thread: Doing a quick google yields a few examples with the ESP8266. Looks fairly similar to the C# way. Just remember there are 3 packet types with different lengths. So I don't see getting the data being the issue. I also don't think the struct side of things to then decompile the byte array into something you can work with, should be that terrifying. Looks like structs in Arduino are closer to the Windows C++ counterparts (as you may expect I guess). Or if you only want specific info, then just walk up the byte array until you get to the bits you're after.

Failing that you could use vrHive as an intermediary and let that do the heavy lifting with the UDP stream and then connect the Arduino via serial and consume the serial stream from vrHive, which is formatted in a much simpler manner. But that's not really what you asked

Client/Server example for the ESP8266 (looks like you may have to login tho)

Thank you

Using the vrHive Data seems to be a good way, maybe I will try it. Maybe the easiest way. But the Box should be acting alone and it has to be connected with the PS4 as a native Keyboard. So the USB Port is already busy. Or I have to use a second one to connect too vrHive. Have to look into it .

...But the Box should be acting alone and it has to be connected with the PS4 as a native Keyboard...

That probably precludes the use of vrHive then, as it needs to communicate over serial with the Arduino. So maybe not simpler, but the original thought of keeping it all under one roof and code just in the Arduino is probably better.

With that said I did buy an Ardunio Leonardo a while back to see if I could get that to work as a HID device in Windows and still receive serial traffic from my app, so that may be an option, tho that might be over the same connection. I don't know enough about PS4 button boxes TBH to really comment

I've go to bed, but will answer you tommorow, ahm later and make a draw of what I need. Have a look into my Signatur for the Buttonbox. Just a HID Device/Leonardo to map the ingame buttons for the right feeling . But it would be cool to get some Input via UDP to let the ABS TCS LED blink, blink when an opponent is right beside you or, if I would be a brain in C+, display informations on a LCD or use a analog RPM display (dont know the english word). It's imho a mix of digital and analog technic . Do you copy that? Over and out

Not too much I can help here at the moment, but good Idea Memoric, I will def. follow this thread.

It looks like the standard Arduino libs support reading UDP over ethernet:

https://www.arduino.cc/en/Reference/EthernetUDPRead

The UDP stream is pretty straight forward. It's a stream of null bytes with the payload arriving with a 3-byte header, composed of the build number (2-bytes) and packet type (1-byte). Read in chunks, grab the headers and dispatch to a parser that unpacks the payload. No need for vrHive.

I didnt get it. Tried it one evening to use the ESP8266 with a leonardo, but imho its to complicated for a arduino/c++ noob. Does nobody want the same? It would be cool to use a analog rpm etc. with the arduino. No one? Reeeeeaaally??

Fully supporting this idea but not sure if I'm capable for such an c++ project!?
