I learned all the signals from the remote that came with CMX Android Box using RCRP05B. IR file has been uploaded to http://www.hifi-remote.com/forums/dload.php?action=file&file_id=12946
I'd like to convert it to device upgrade format, so I can use it with extender. But IR/RM are unable to decode the protocol. Would appreciate if someone can help me doing that. |

Just so you know why the learns don't work: The Matricom box uses the NEC1 IR protocol which implements repeats using "dittoes". That means it sends the actual signal just once, and then a simple pattern repeatedly. This repeated pattern is the same for all functions.
All of the learns you posted contain only the dittoes, and none of the actual information-containing signal. When I have that problem, it is because I have either pressed the button on the OEM remote too soon or had to move the two remotes in order to get the learning remote to start recognizing the IR. Since all of your learns missed the beginning of the IR transmission, I suspect that you need to first press the button on the RCRP05B, wait a second, and then press the button on the OEM remote. This generally happens naturally for me while I fumble with the remotes! |

You are absolutely right. I learned the signals again as you suggested by holding RCRP05B first and then OEM and this time IRDecode decoded the protocol successfully as NEC1.
Thanks a lot, that allowed me to get the OBC code for a missing button "return" |
