I have a Flirc V2 running on a raspberry pi headless. Using the device log when I press the increase temperature button I get this (I just press the button one time but get what looks like to me to be two outputs): :e:0 371,454,375,454,372,453,372,453,372,423,406,424,405,424,406,484,354,454,375,454,371,454,376,454,371,454,1226,484,353,454,1226,454,371,458,371,454 :e:0 376,454,371,449,380,458,371,429,396,453,372,453,371,450,384,454,371,454,375,454,371,454,371,454,371,424,1264,454,371,454,1230,450,379,454,376,423 I am now trying to use the sendir command like this: flirc_util sendir --pattern="371,454,375,454,372,453,372,453,372,423,406,424,405,424,406,484,354,454,375,454,371,454,376,454,371,454,1226,484,353,454,1226,454,371,458,371,454" --repeat=1 --ik=40000 and I get this error: [E] util/flirc_util/src/cmds/ir_transmit.c sendir(101): Error: buffer should lead with zero But if I add a zero at the beginning like this, I get a different error: flirc_util sendir --pattern="0,371,454,375,454,372,453,372,453,372,423,406,424,405,424,406,484,354,454,375,454,371,454,376,454,371,454,1226,484,353,454,1226,454,371,458,371,454" --repeat=1 --ik=40000 [E] util/flirc_util/src/cmds/ir_transmit.c sendir(96): Error: invalid length, must be even I also tried recording the on/off button with similar results. I noticed the codes are always a little bit different everytime. Do you have any suggestions? Is controlling a minisplit something the Flirc can do? Thanks for the help!
