how to send IR commands implemented in NEC2-f16 protocol #839
-
|
Hello ! I have sequences of an equipment that I decoded using a converter tool at http://irdb.tk/convert/ . I found that the same equipment uses two sets of commands: one using NEC2 protocol and another set using NEC2-f16 protocol. But for any command of the other set NEC2-f16, I was not able to find a way to send. For example, for this result below, decoded at http://irdb.tk/convert/ : for this original sequence in raw hex: 0000 0077 0000 0022 013B 009C 0013 003A 0013 003A 0013 003A 0013 0013 0013 0013 0013 0013 0013 0013 0013 003A 0013 0013 0013 0013 0013 003A 0013 0013 0013 0013 0013 003A 0013 0013 0013 0013 0013 003A 0013 0013 0013 003A 0013 0013 0013 0013 0013 003A 0013 0013 0013 003A 0013 0013 0013 0013 0013 0013 0013 003A 0013 0013 0013 0013 0013 0013 0013 0013 0013 05BD I tried approaching as 16 bit address + 8 bit command + 8 bit inverted command = 2487A55A But it was clearly missing something as the code is not even using "misc = OBC2=8" (I do not have a clue what is it). As I told you, I succeeded using IrSender.sendNEC(sAddress, sCommand, sRepeats) ... not sure if for IrSender.sendNECRaw(tRawData.ULong, aNumberOfRepeats, aIsRepeat) it may be missing some other set in any ".h" file. How would be IrSender command line for it? Antonio Moraes |

Hello Armin, As a note, just to mention: I am trying to send IR commands to an old equipment without remote control (descontinued and very specific), but still I assessed this documentation with the sequences. Using Arduino-IRremote library I could send correct comands to this device, but just those implemented in NEC2 protocol. I have not found any example in the library for NEC2-f16 protocol, that seems to use 16bit addresses and 16 bit commands. |

Hello Armin,
Thank you for your response!
I really didn't want to break any rules ...
Perhaps a more direct and concise question:
How to use the Arduino-IRremote library to send commands in the NEC2-f16
protocol? Is there an example for this use?
How the code would be for this case: "Protocol NEC2-f16, device 135,
sub-device 36, OBC 165, misc = OBC2 = 8".

Armin , should I open another issue with just the text highlighted in blue
above?
Can you help me?
Thank you,

1. Please do not open an issue here, if you have problems with any
obscure IR software!
2. A raw sequence can not contain 0000 values and the last value 05BD
is also nonsense.
3. Use the examples of the library e.g. the SmallReceiver and you will
see the received values, you can use for send.

There is the Discussions tab, where you can place your questions. Is it not visible for you? Maybe you have no access rights? And please look at the examples!!!!!! and also here: https://www.sbprojects.net/knowledge/ir/nec.php |

Please give me feedback how to guide people to use the discussions tab for
such type of help requests!

Then you understand, that there is nothing like a "NEC2-f16 with OBC2"
protocol and you simply can send all 256 commands of your remote for
testing, since the address is constant.

Hello Armin,
Yesterday after your definitive comment 'there is nothing like a "NEC2-f16
with OBC2" protocol' I decided to implement a sender of the PRONTO
sequences, leaving behind the ideia of sending by a protocol (I had said
they were raw, I was wrong the sequences were PRONTO sequences)... and it
worked.
I was able to send these sequences (identified as NEC2-f16 protocol by the
online converter tool at http://irdb.tk/convert/) and the device responded
to that accordingly. (The device is an automation center that was given by
construction companies to control lights , blinds, etc, in the houses they
did at that time. Although the system had infrared sensor for receiving via
IR remote, the remotes have never been given, and the model is
descontinued; something that have never been missed by the buyers. These
houses were of high class standard ) .
But this was the first step for the intent of connecting it in an Alexa
system. So I tried to make the IoT InfraRed Universal Hub (Alexa
compatible) learn this sequence from my Arduino implementation... and
although it recognizes that it captured the sequence, when you execute the
sequence the device simply ignore. So it seems that this "malformed"
sequence is not able to fit well in any protocol that my IoT InfraRed
Universal Hub could have as templates.
This is the PRONTO sequence:
0000 0077 0000 0022 013B 009C 0013 003A 0013 003A 0013 003A 0013 0013 0013
0013 0013 0013 0013 0013 0013 003A 0013 0013 0013 0013 0013 003A 0013 0013
0013 0013 0013 003A 0013 0013 0013 0013 0013 003A 0013 0013 0013 003A 0013
0013 0013 0013 0013 003A 0013 0013 0013 003A 0013 0013 0013 0013 0013 0013
0013 003A 0013 0013 0013 0013 0013 0013 0013 0013 0013 05BD
On the other hand, the sequences simply identified as NEC2 have been
perfectly learned by the IoT InfraRed Universal Hub.
I am disappointed that IoT InfraRed Universal Hub somehow seems to
identify a code when learning but when reproduces something different that
is not accepted by the automation center.
You are a specialist in this matter, do you think there is a workaround to
solve it.
Thank you
Antonio Moraes

Very interesting project! |

Very interesting project!
The Pronto codes are Onkyo protocol codes, which is NEC with 16 bit instead of 8 bit command. (therefore the OBC2=8).
I added the protocol to the library now. Now you should be able to generate the missing signals by sendOnkyo, instead of sendPronto. Maybe it helps for your project.
