Arduino Mega and Wireless Communication

[kwongmingyou]

Hi, everyone. Now I am doing a computer controlled robot. I used Bluetooth module to communicate between my PC and my arduino mega, and it is success. Now I wanna to have a wider range, I replace RF module to replace Bluetooth module, I found that the communication between PC and Arduino Mega is 'unstable', sometime it can receive and sometime it won't. Anyone have the idea to make the communication more 'stable'? Or, any wireless device I can use to get wider range?

Low cost RF module is not meant for serial communication, it is designed for remote control.

You should try the XBee Series 1, Series 2 or XBee Pro.

I see. isn't there any other wireless device I can use instead of XBee? Thanks again. Have a nice day.

WiFi module, but it is more expensive....

Or other type of non common wireless protocol such as MiWi fro microchip.
