I am working on a project and i have an Arduino r4 wifi which has built in esp32-s3 and an arduino nano which has built in esp32. I want the nano to have a joystick connected to it which can be handheld and be able to connect tp the R4 either bluetooth or through wifi to control the motors. How would i be able to connect these 2 arduinos as i cant find anything online about it
Hmmmm 
… can you get your hands on another nano ESP32?
With 2 esp32’s you can use the Espressif ESP-Now protocol … if there is a way to load firmware onto the r4’s esp32 module, then I guess it is possible?
This is the issue. I can’t find any information regarding the r4s esp32 module… or atleast any useful information. Ideally I’d like to try utilize the r4s built in module but if I have to I will consider getting another nano
Hopefully 
, Arduino was smart and somehow made it so the esp module on R4 is accessible for this sort of situation??… but then comes the task of getting the data from that module over to the main mcu of the R4 through the serial connection ??
Anyways, way above my head. Someone super smart will chime in soon 
. Unfortunately, Another nanoesp32 or even a cheap esp32 devkit from AliExpress for 5$ if you have time to wait for delivery may be much easier
What do you need to know?
There's Arduino's IoT Cloud.
And take a look at randomnerdtutorials.com
for more ideas about doing with WiFi.
