Topic: using remotexy with integrated esp32

I asked earlier about using an arduino wifi rev 2 with remotexy but the administrator said he didn't know whether it would work. I have since done some research and found this board uses an integrated esp 32. On the remotexy website, it says there is support for this module. in the module interface on the editor there is only options for an esp 32 board. Is there a way to use remotexy with an integrated esp32?


Re: using remotexy with integrated esp32

RemoteXY can work with any board that is using the Arduino framework, there is no magic, all it does is send/receive data to/from wifi/bluetooth/serial/whatever. What did you try ? You may need to write a custom interface but it's not hard at all (look examples in the remotexy/modules folder).


Re: using remotexy with integrated esp32

I am using this example code for an AP connection:

And the simple webserver code included in the wifinina library. I had a look at the examples for the remotexy library, how would you go about linking these two codes?

I tried calling some functions from the example code on a remotexy esp32_core sketch but received some error messages. It seems that i need to define a function for the integrated esp32 module.

Re: using remotexy with integrated esp32

It seems that you are using an old version of remotexy library

And as I said, you possibly have to write your own communication module, look for example https://github.com/RemoteXY/RemoteXY-Ar … ore_wifi.h

But there is not much differences between the esp wifi library and wifinina library, the only dfference I can see is wifinina library use "wifi.beginAP()" and the esp32 wifi library uses "wifi.softAP()", so maybe a simple workaround is to add #define softAP beginAP before #include <RemoteXY.h>

One thing I hate in the default modules is that they do all the wifi setup internally and leave no choice for the user. This is why I create my own modules where I remove all the wifi setup, for example this one allowing to use wifimanager library: http://forum.remotexy.com/viewtopic.php?pid=2514#p2514
