In this video, I show how I analyzed an unknown digital signal on a remote control for a Google Smart TV with a logic analyzer. I used the PCBite probe kit to connect to the test points without solder.

A video on the process of decoding would be incredibly interesting! What tools you use, common patterns you know, etc etc. Really enjoying all of your videos, keep it up :)

This explains why I gotta wait between button presses on these "smart" remotes. Channel surfing is dead now.

Cool but you should be able to solder to those points with no issues, those pogo pins just cause more problems than there worth...

2F seems to be transmit, 5F might be receive? (Not sure) I noticed additional patterns in each of the messages as well. It seems each message has three messages in it. I've broken them apart before. As you noted, the same byte is sent in position 3 for each of the three parts, which is always followed up be 48. Perhaps the 3rd byte is a sort of message id for the current packet? 2F 8A7D 48 0A08 2F 9A7D 48 0A08 5F FA7D 48 690D1828F8 2F 3FA8 48 0A08 2F 2FA8 48 0A08 5F 4FA8 48 690D1828F8 2F F9AC 48 0A08 2F E9AC 48 0A08 5F 89AC 48 690D1828F8

Hi. Thank you for the video. I have a question. The blue LED in the logic analyzer is on all the time, and Logic2 shows that the device is starting from a high state. Is it damaged or is it supposed to be like that?

7:43 1 Million (Translated to BAUD) is Sym/s SYMBOLS PER SECOND Not Samples and 1MHz is Frequency not BAUD, 1MHz doesn't have to mean 1 Million symbol changes per second, you could have 9600 Symbols in that time, it depends on the BAUD RATE in use in the protocol but.. you were looking for BAUD RATE... in SYMBOLS per second Sym/s or Sym/sec or even Bd

8:35 it's not Binary Protocol. it's likely NEC Protocol Binary isn't a protocol. it's a Numbering system and a Language, it's not a Protocol also you just said it was HEX so....
