Sorry if any of this is confusing…I have a few questions:
If I record a raw sub ghz signal, at 315mhz for example, can I somehow copy that signal and create a new file with that signal being sent over and over again, instead of just the 1 time I recorded it? Similar to an audio file…take part of a wave form, copy it, and then paste it somewhere else or in a new file etc.
Is there a way to see the raw data, and not just the wave form/signal? In other words, when I read a tire pressure monitoring sensor, for example, using a tpms tool (which activates the tpms with a 125 khz wake-up signal), the tool shows hexadecimal data for the tpms ID (8-digit), pressure in psi and sometimes temperature…obviously all this data is IN the signal being sent back from the tpms sensor at 315 mhz…but how can I see this data using the Flipper Zero? Or is it just not possible? Most automotive stuff is always hexadecimal, converted from raw binary or can voltage differential, so I’m just not sure how or if Flipper can do any of this stuff?
Basically continuing with the last question…if this raw data could be saved and viewed, could it also be edited and create a new file for replaying? Here’s the easiest way to summarize what I mean…
- I use a TPMS tool to activate a 315mhz sensor
- I capture and save the raw data using the Flipper Zero (I’ve already done this a bunch times)
- I somehow take this signal/file saved and view the raw data (psi, temp, tpms ID etc)
- I somehow edit this raw data and change the information for replaying (for example, take a tpms with an ID of 4F65EED2 and change it to 784AA5C1B…for exmaple
- I’m assuming that the 125khz used for RFID work is completely different than what vehicles use for proximity/smart entry etc? As well as transponder chips? I know that automotive transponder chips use 125khz for data transfer when you’re starting your car, and proximity systems use this same frequency when unlocking your car using the exterior door handle sensors etc…but none of these are picked-up by the Flipper, under any option…so that must mean even though RFID tags use the exact same frequency, they don’t operate that same way?
I hope I’m making sense…just trying to learn. I wanted to start with Flipper and move to HackRF and PandwaRF later on.
