I need to use a VMA 205 (ESP8266 wi-fi module) but the only thing i reached is ping the ip address when using the TCPUDPDEBUG software. Everyone talks about 3.3V current, but even i tryied an industrial power supply with capacity of 3A but always i get error when try to send anything to arduino.
Looking at the internet it seems noone knows nothing about the way to put it working…
What is the problem? Can Velleman produce a simply and easy way that people can understand how to put it working?
