Problem with Pace UPC mediabox remote control

Other Hardware Sensors
1

Hi,

I am currently making a lan connected arduino remote control. And all works fine for most products.
Util I came to the Pace UPC HD Mediabox.
The stupid thing seem to use some protocol called rcmm.
But no problem there are even on the internet examples with sending and receiving rcmm.
Well none of them work for me. What kind of rcmm program I load, whenever I try to listen to my remote control it says type unknown.

When I output the buffer data, i never get anything recognizable.
I get variable input for the same button.

I used this program:

I am already puzzling all day on this. All the RC5 devices were so simple to program.

I need to read my remote's codes and then I want to replay them on the ir led.
I already found some source that gives me a unique hash based on the input. But a hash is not something I can resend.

Nobody?

I had a look at some of your signals & it looks like the IR receiever you are using is struggling with the signal
..see attached screen shot. (make sure to point the remote directy at the receiver and within 1m.

What is the model of your IR receiver?

RC-MM is 36kHz modulation (usually)

If all else fails you could try:

38KHz Infrared IR Transmitter Sensor Module For Arduino
that's all i know. So i need a 36kHz ir led?

What's the difference? should i buy and connect a second led?

Normally a 38kHz receiver would work for 36kHz (with reduced performance).

However, it depends on the quality of the receiver. (There are some poor quality ones about)

Any model number?

Assuming you have an IR LED etc why not try the alternative in the link I posted. It works quites well.
(Best to try that before buying a new one, in case the issue is something else.)
