Remote Control for ESP32 (off the shelf)?

[brassgoggles]

I am currently remote controlling a 'single' ESP32 Wroom Development Board via a 4 Channel RF Module (YK04).

Is there a similar 'off the shelf' commercial remote that I can use to directly control the ESP32 (minimum of 4 buttons required). I also need this to be the size of a car remote or very similar?

You need to tell us much more. What sketch is running on the esp32 (post all the code in code tags)

Information needed to Assist with Your Problem:

I find your question interesting, but I have a problem understanding your setup. After reading your description, I still have no idea what your actual configuration looks like. To help you better, please provide the following:

1. Annotated Schematic: Post a clear, annotated schematic of your setup showing all connections, including power, ground, and any power supplies. I do not work with Fritzing diagrams or unclear pictures. However, a readable photo of a hand-drawn schematic is perfectly fine.
2. Technical Details: Provide links to the technical information for all hardware components used in your setup. There are many different and sometimes incompatible devices that look similar but behave differently, so it's crucial that we have accurate information. Avoid linking to marketplace sites like Amazon that often lack detailed specifications.
3. Why This Matters: All you want is to make everything work together correctly, and all we want is to help you achieve that. By providing the correct details, we can offer more targeted and effective assistance.

Hopefully this will better explain the project. I have a ESP32 Development Board connected to a YK04 wireless module ('master' unit). When the YK04 recieves a signal from a 4 button RC, the ESP32 transmits data via a NRF24L01.

The data is received by a 'second' NRF24L01 connected to a 'second' ESP32.

I initialy tried using the two ESP32's to directly send data to each other via 'ESP_NOW', this proved to be too slow and inconsistent, times varying from 2 to 20 milli second.
By using a pair of NRF24L01's the transmission time is now consistent at 80 micro seconds.

To save physical space I wondered if it's possible to eliminate the YK04 receiver and make use of the built in WiFi receiver of the ESP32? Is there a commercial RC that will directly communicate with the ESP32?

Sending the code for the project has no benefit. The code and data transmission works fine.
