IR blaster functionality

[davem]

 

Lirc is so under-documented and lags several releases behind any current OS...users generally have to experiment with major breakage before one stumbles upon a working recipe...only to find an update kills it all.
Elsewhere I use Flirc... but some mapping and keycodes would be needed for Snakeoil.  Triggerhappy is the go-to currently for Flirc.
Maybe AK could add it to the todo list...but you or I could do some research too...

Thanks Bromf,

I will do some reading when I get a chance. I only need 2 codes (vol up/down) and I have them already.

I am getting a bit stuck and would love some suggestions. (luckily work has been quietish the last couple of days..) I bought the jaycar emitter plugged in the headphone jack of my NUC. Eventually worked out the right config details. When I do an IRSend, I cant see any signal when viewing with my phone camera.[edit: just confirmed that the camera does not pick up output from the emitter, so ignore that point] In the log its misleading - the earlier part suggests an issue unable to connect to a socket but later it seems to go through without error ! I mean it wouldnt be able to deinit the headphone jack if it couldnt connect ??? Am I reading this correctly ?

done some more testing (mixing up devices etc) and am now confident that I am not getting anything out of the emitter. 

More trial and error and numerous reloads of lircd and the errors have disappeared. but nothing in irw (not really sure yet if I should see anything in irw...)
