Thanks Bengt:

Setting the frequency to 0 in lircd.conf did not make any difference when I ran irsend on source RPI3 and monitoring the receiving Rpi3 gpio22 using mode2 -d /dev/lirc0.
I have  lirc (0.9.0~pre1-1.2) installed on both RPI3.
I'm not sure if I have the latest version that supports frequency feature.

I added "frequency 0" to the lircd.conf which was originally generated using the irrecord utility..  I'm not using the optocoupler. Does the "invert=on" invert the waveform completely or should I manuallymodify in the lircd.conf? Since there is no remote control there is no need to invert to save battery power.
