Okay so I can't find code after hours of searching on how to wirelessly control a dc motor with an L298n and Uno Wifi Rev2. I simply need the motor to spin all full speed when on and not all when off. Could someone either point me in the direction of help or code that is completed? I am at a loss.
loads of example out there on how to interface an arduino with the L298 driver
same with the wireless interface!
have a look as this one for example:
https://www.elithecomputerguy.com/2019/06/arduino-uno-wifi-turn-led-on-and-off/
its an exmple to turn an LED ON/OFF wirelessly. so now all you do is combine this code (if you wish) with a LN298 code 
Hope that helps....
Use a transistor to turn it on and off.
