Hello,

Today I was trying to create a simple program to test wireless modems. I set up two Advanced Computers and equipped both with Wireless Modems.

I created two programs, TestSend (for the first PC), and TestRec(ieve) (for the second one). The first one works fine, I loaded both on each computer with os.loadAPI at the Lua prompt, but whenever I try to call the function "recieveMessage" on TestRec, it says: "Attempt to call nil".

Here's the code of both programs.

TestSend: http://pastebin.com/7JzLZyCr
TestRec: http://pastebin.com/vEFPi423

Any help is appreciated :)/>

You misspelled "recieve" Therefore you get attempt to call nill on


senderID,message = rednet.recieve()

It's spelled receive.

Thanks a lot :)/>

I do not speak English natively, so my orthography is not perfect.

Thanks again :)/>
