Helo
I have a problem with the communication from my arduino Uno to the Xbee. The Xbee is connected to the network via a router and i can ping it with my computer. The problem is when i try to send something from my arduino to the Pc via xbee nothing hapeens.
please can anybody can help me.
here is the code from this link GitHub - cjbearman/xbee-wifi-spi-arduino: Arduino library to support Xbee Wifi modules, using SPI communication
