The t1 wireless network card will not return any "modem_message" signals despite otherwise appearing to work. The card can send signals, and even respond to wake messages but refuses to generate any "modem_message" signal. If the t1 card is replaced with a t2 card in the receiving computer, the signal is generated as expected.

Simple signal logging script I used:
local component = require("component") local event = require("event") local m = component.modem m.open(1) m.setWakeMessage("string") while true do --get args, print signal to shell local t = {event.pull()} print(t[1]) end

Simple broadcast script I used:
local component = require("component") local m = component.modem m.open(1) m.broadcast(1,"string")

I also used computer.pullSignal() instead of event.pull() and got the same result.

This is a known issue: #3444

It has been fixed in Git but has not made its way to an official release. Build from source or use the CI build ( https://ci.cil.li/job/OpenComputers-MC1.12/ ).

Okay thank you.
