Hi guys,

I try to set up a decent GPS system to navigate alle my stuff with it. The core system is up and running, and i can locate all my positions. The only problem that I've is that I cant send my coordinates over rednet. For example I wrote some code:

rednet.open("top", 1)
x, y, z = gps.locate(3)

vec={ value1=x, value2=y, value3=z}
svec=textutils.serialize(vec)
rednet.send(1, svec)

Now on the receiver side:

  
rednet.open("top", 1)

id, msg, dist=rednet.receive()
vec=textutils.unserialize(msg)
x=vec.value1
y=vec.value2
z=vec.value3

I cant access the transmited values 1-3 It just crashes with attempt to call nil...

Pls help me I'm getting crazy about this

PS:I've checked svec and it was created correct I think the problem is in the gps.locate function, cause if I hardcode the values 1-3 and then transmit the table everything works like a charm.

add in two print statements, and lets see whats going on...

in the sender add this just before you make the vec table

print('X: '..tostring(x)..' Y: '..tostring(y)..' Z: '..tostring(z))

and add this to the receiver

print(msg)

what do they say?

Also just an FYI, rednet.open only accepts 1 parameter, the side, so the 1 in both those function calls are not needed.
