What does "RX only in your area" for sub-GHz garage door mean?

Sub-GHz
#1

Hi all,

New to Flipper Zero, but I’m trying to record my Multi-Code Linear 300 garage for remote. FLIPPER has that model in its database and I’ve successfully saved it, but when I try to use it I get the following response: “This frequency can only be used for RX in your area.”

What does this mean and can I still use it to open my garage door?

Thanks,

Bob

This means that it is illegal to broadcast on this frequency in your region. Your garage system may be imported from another region or separately certified, but the flipper is locked to not allow broadcasting on that frequency, as we otherwise wouldn’t be able to import it into your region.

Thanks Astra - however, these systems are sold all over Northern California where I live and the one I have is 25 years old.

Just for curiosity, how does Flipper know where my “area” is? It seems unlikely that the system is restricted by areas, but regardless, can I do anything to make it work, short of changing my garage door penning system? :roll_eyes:

Flipper’s region is determined by your shipping address. There are 3 regions: R01, R02, and R03. Yours is R01, the American/Australian version.

Your gate was probably certified for sale in California, but not in the US generally. The Flipper had to be certified for the whole United States, so we couldn’t include those frequencies.

There is no way to unlock transmission on those frequencies on our firmware.

Hi,

Could you please explain this a bit further ?. I wasn’t able to find anything about these zones and i’m worried about the utility of this tool as a pentesting device if i can’t emit in some specific frequencies, what is Europe’s one , what frequencies are forbidden to emit in, etc

Thank you in advance

Here’s the docs page with all the frequencies and other info.

Hi again Astra - sorry to beat this topic to death, but is there a way to hack my Flipper so that the area code can be changed? Can you please let me know where the code is stored and if I can edit it if I can attach it to my PC via USB?

Thanks,

Bob

First of all, I’m not able to give you any instructions on removing the restrictions we have specifically made, that would both be illegal and would invalidate the point of restrictions in the first place.

The region is stored in the OTP (one-time programmable) part of the MCU, there is physically no way to change it after it was first programmed.

Once again, just to reiterate: there is no way to change the region as it is read-only, and broadcasting on non-allowed frequencies without a license is a crime.

Thanks Astra - I understand, so I’m done with it.
