HI Guys
I've build a robot car using arduino/b4A connecting with BlueTooth, using AsyncStream to transfer data both ways (Which work pretty good).

Lately I come accross this wifi/video/ttl module (HJMCU) (See attached Pic)
You can connect with Wifi to stream the video (Can use webview) and then it also have 3 wires for TTL connected to arduino rc/tx pins.
I want to use this, as a replacement for bluetooth connection,

This car (https://www.aliexpress.com/item/FOR...-car-kit-FOR-arduino-car-four/1905434008.html) use the module with a arduino/Android APP, so somehow it must be possible.

Anyone with some suggestions? how I can get this to work?

Thanks
Danie
