Q about -A and disabling decoders #2510
-
|
I have a question please, about decoding an unknown device. I picked up a GUTA branded TPMS and am trying to see if I can figure out the protocol. I believe it’s on 433.92MHz, but only because their repeater mentions that frequency on the Amazon page. I have two other 433MHz devices in the car – a Nexus and Acurite temp sensors. rtl_433 picks them up and displays the data beautifully! What I thought would be a good idea would be to disable the Nexus and Acurite decoders, and then run with -A: rtl_433 -R -19 -R -11 -R -55 -A My question is, will the output from -A now have the Nexus and Acurite filtered out? Will the output of -A just be, what I presume to be, the TPMS system? |

The decoder options only enable/disable decoders not the reception. The analyzer will always see all transmissions. |

Thank you! That makes sense. I'll try that |

But if you leave the decoders enabled and opt to save transmissions with
-S unknownyou'll likely only get the TPMS as saved files.Then run
-Aon each file. That way you can inspect the transmissions later and try things.
