Hi Every1,
I am trying to get the signal strength reading from the motes and so i
modified the TOSBase program with reference to the available source codes in
the net. the program is getting compiled but i am not getting any result
when i run the Oscilloscope program. Its getting struck,
[EMAIL PROTECTED]:57600resynchronising..... and its not printing anything.
Can any1 please verify the code and let me know what the mistake is. Since i
am very new to tinyOS, i need lot of help from you all.
Thanks All in advance.
