how to record an ir signal from an AC remote using LIRC in raspberry pi? - raspberry-pi

Question

i had already used the LIRC of the raspberry pi to record and use the IR signals of a samsung TV remote. the recording process was fine. i used this site for reference.But now i am unable to record the IR signals from a bluestar AC in the same method. After 1-3 dots (not always the same number), irrecord exits with the following error message:
irrecord: could not find gap.
irrecord: gap not found, can't continue
then i tried recording the AC remote signals using mode2 and routing it to a text file and manually modified the lircd.conf file to include the raw code as shown in the link
How to use irrecord with 2ms timing instead of the default 5ms?
but then i get the error that
irsend: command failed: SEND_ONCE /etc/lirc/lircd.conf KEY_POWER
irsend: unknown remote : "/etc/lirc/lircd.conf"

Answer 1

Possibly lircd doesn't accept all characters (e.g. slash) for the remote name. Try changing the:
name /etc/lirc/lircd.conf
in the .conf file to a different name (e.g. MY_REMOTE), then invoke the irsend like:
irsend SEND_ONCE MY_REMOTE KEY_POWER

Answer 2

The air conditioning controls send more bits than the television ones for example. You have to configure the lirc.conf header as:
begin remote
name IRAIR1
bits 48 #Configuración para 48 bits
flags SPACE_ENC
eps 30
aeps 100
header 3388 1678
one 430 1257
zero 430 412
ptrail 428
gap 108399
begin raw_codes
name KEY_POWER
3478 1676 500 1218 501 388
472 ..................................
end raw_codes
end remote
I think exactly what 48 bits are sending. This guy explains it: http://absurdlycertain.blogspot.com.es/2013/03/lirc-raspi-remote-control-configuration.html
Do not forget to restart the device, with me it does not work if I do not.
Sorry for my English
