hi all. first of all, sorry for my bad english, im francophone. im trying to do like the industrial info panel in ftb bu without it cuz i dont have access to that mod.

for the moment i got a teste code to make it work but it don't

on the sender computer:

rednet.open("left")
nucleair = peripheral.wrap("back")

local a = nucleair.getHeat()
local b = nucleair.isActive()
local c = nucleair.getEUOutput()
c = c  * 5

local a2 = tostring(a)
local b2 = tostring(B)/>
local c2 = tostring(c)
local donnees = { b2, c2, a2}
local encode = textutils.serialise(donnees)

rednet.broadcast(encode)

print(a2)
print(b2)
print(c2)

and on the receiving computer:

rednet.open("left")
local num = 1

while true do
  event, id, text = os.pullEvent()

  term.setCursorPos(1,1)
  print(num)
  num = num + 1
  if event == "rednet_message" then
    recup = textutils.unserialise(text)
    print("1 = "..recup[1])
    print("2 = "..recup[2])
    print("3 = "..recup[3])
  end
end

i kow for the moment this can be look ugly on a terminal but when it will work ill arrange it on a monitor,

all i want to do is sendig via wireless modem the status of the nuclear reactor, the energy output and the actual temperature. for the moment it don't work!

thanx to all

What DOES happen?

ok i do some correction in my program but it s still dont work. on the receiver computer it say :

(the code in the computer is named 1)

1:33: attempt to indez ? (a nil value)

here's the code:

rednet.open("left")
local monitor = peripheral.wrap("top")
term.clear()

monitor.setBackgroundColor(colors.black)
monitor.clear()
monitor.setTextColor(colors.lightBlue)
monitor.setCursorPos(1,1)
monitor.write("Centrale Nucleaire")
monitor.setTextColor(colors.white)
monitor.setCursorPos(1,3)
monitor.write("Reacteur : ")
monitor.setCursorPos(1,4)
monitor.write("Energy:")
monitor.setCursorPos(1,5)
monitor.write("------------------------------------")
monitor.setCursorPos(2,6)
monitor.setTextColor(colors.orange)
monitor.write("Coeur du reacteur")
monitor.setCursorPos(1,8)
monitor.setTextColor(colors.red)
monitor.write("TEMP:")
term.setCursorPos(1,1)

while true do

  event, id, text = os.pullEvent()
  if event == "rednet_message" then
	recup= textutils.unserialise(text)
  end
monitor.setCursorPos(10,3)
monitor.setBackgroundColor(colors.cyan)
monitor.write(tostring(recup[1]))
-- if recup[1] == true then
--   monitor.write("OUI")
-- end
-- if recup[1] == false then
--   monitor.write("NON")
-- end
monitor.setCursorPos(10,4)
monitor.write(recup[2])
monitor.setCursorPos(10,8)
monitor.write(recup[3])

end

and the code of the sender

rednet.open("left")
nucleair = peripheral.wrap("back")

while true do

local a = nucleair.getHeat()
local b = nucleair.isActive()
local c = nucleair.getEUOutput()
c = c  * 5

if b == true then
  b2 = "oui"
elseif b == false then
  b2 = "non"
end

local a2 = tostring(a)
local c2 = tostring(c)
local donnees = { b2, c2, a2}
local encode = textutils.serialise(donnees)

rednet.send(12, encode)
end

If the event you receive is not a rednet message, you don't ever set recur, since recur isn't set that's why you're getting your error.

Change this line:

event, id, text = os.pullEvent()
--#To this
local event, id, text = os.pullEvent("rednet_message")

Also, good tutorial on variable scope and why locals are better.
