When working in AP mode, our robot car itself will become a Wifi Hot Spot. Our cell phone 
can connect to Robot Car as its wifi client. The IP address of Robot is fixed as 
192.168.4.1 and It is not connected to WAN. 
(1) Please download sketch from following link: 

https://osoyoo.com/driver/mecanum/mecanum-2560-lesson5A.zip

. Unzip the file and you will 

see a folder named mecanum-2560-lesson5A,   upload the code into Arduino 

 

(2) Open your Arduino Serial monitor and set 9600 baud,then you will see a similar result 
as AP mode. A new Wifi SSID “osoyoo_robot” with IP address 192.168.4.1 will show up in 
the window. This means your Robot car has a Wifi Hot Spot name “osoyoo_robot” , its IP 
address is 192.168.4.1

 

(3)Now your Robot car become a Wifi Hot Spot and set IP address as “192.168.4.1” to 
your APP Setting section.
