How to correctly detect the order sent using the IR signal for active automatic search?

[arlaor]

Hi @crankyoldgit
I am using the latest version of IRremoteESP8266 on a nodemcuV2 esp8266 module, I have the following situation. I have extracted the commands sent by the remote control of a JVC stereo mini-component and placed them within a web page, to be sent from this page. I haven't had any problems with this, but there are a couple of buttons (<<fast left / reverse search and >>fast right /forward search), that have a special function when I'm searching for a radio station. From the remote control of the mini-component, pressing the button once moves one unit on the dial, but if I press it for a moment and stop pressing it, the order that the mini-component receives is to move continuously, until finding the nearest station.
I have tried to simulate this function from my website, causing the commands to be sent every 20 milliseconds when pressing any of the buttons that contain the mentioned functions, so that the mini-component enters automatic search mode for radio stations, but it has not worked. been possible, since what the minicomponent does is move the number of units while the button is pressed and ends as soon as the button is released, as if it were sending the command through multiple commands. button press.
How can I make these buttons generate the automatic search signal when pressing and holding the button?
Note: the command that the remote control sends when you press it once is the same command that it sends when you hold the button down.

Please read the FAQ before posting.
If filling an issue make sure to answer the questions in the template, otherwise use discussions.

By collecting the data as explained in the template we might be able to understand what your remote actually does.
A guess is that it sends with repeat and a specific gap.

You could try different values for repeat.

Thanks @NiKiZe .
I have used repetitions starting from 20 milliseconds to 220 milliseconds, without being able to activate the automatic search mode.

Send has repeat parameter, you select number of repeats, not time between them, since that hopefully already is correct.

You have not given details to help further.

@arlaor As @NiKiZe points out, you probably want to use the repeat parameter in the the sendJVC() function. Some protocols do not just re-send the same message for a repeat, they have a special signal. The repeat parameter does the right thing.
i.e. Don't do:

for (int i =  0; i < 5; I++) {
  IRsend.sendJVC(FAST_FORWARD);
  delay (100);
}

Instead do:

// Send the FAST_FORWARD button with 4 repeats (5 messages sent) to simulate holding the button down.
IRsend.send(FAST_FORWARD, kJvcBits, 4);

Hi @crankyoldgit @NiKiZe
I have tried to send the commands in the following way:
if (code==0xF97C || code==0xF9BC)
{
irsend.sendJVC(code, 16, 4);
}
else
{
irsend.sendJVC(code, 16, true);
}
but it only sends 1 command 0xF97C or 1 command 0xF9BC and not 4 as indicated by the if / else structure. Should I add something else to make the sending of the 4 repetitions effective?

[crankyoldgit]

irsend.sendJVC(code, 16, 4); should send the code 5 times. I guessed at 4 repeats, you may need more. Dunno.

Are you sure your code is executing that line?

How are you certain it is only sending one message?

Do you have the output & rawData from an IRrecvDumpV4 etc from the ESP sending the message, and how about from the actual remote when you do the operation you want to happen?
