[App_rpt-users] RTCM/chan_voter/event management subsystem

Thanks Bryan, let's try this again... my original email was a total edit
fail lol.. so I can see where it would be confusing. I had first sent this
to someone else prior to posting to the list.

is your xmtr on the rtcm or are you using voted receivers and one xmtr

I am running a pair of CDM1550's UHF in full duplex off of an RTCM. The URI
will be used to for another yet be implemented application, but the idea
was to use one of the GPIO pins from it to drive my fan.

Are you running the background script that k0kn has on his website?  just

Copy that... my issue is that I can't get past the first part, the event
management subsystem does not appear to be picking up the key/unkey events.
When I have played around with this in the past on a URI and simpleusb, I
would see debug messages indicating as such on the Asterisk console.

google k0kn for the scripts from the source, not someone's interpretation

Got those already.

Those are pretty neat! I've run into similar, I actually just replaced the
relay board I was going to use with one of these instead, it's a 3 output
MOSFET breakout board that will turn on each output with 2.5v or higher on
the microcontroller pins:

http://www.ebay.com/itm/301357646243?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

I haven't tried it yet, but it looks very promising. The relay board I had
was giving me fits with the GPIO pins so I started searching for a
replacement and decided to give this a try instead. I will miss the click
sound though... or well maybe not ;)

So in summation, pair of radios running full duplex on an RTCM, trying to
use the event management subsystem to toggle a GPIO pin off a URI. As
explained above, I can not appear to get the event debug messages to show
up in the asterisk console on key/unkey events. That leaves me to the
guessed conclusion that either my configs are wrong (they don't appear to
be) or chan_voter does not talk to the event management subsystem?
