rpitx VS Flipper-IRDB

As someone with a HackRF PortaPack knockoff I got from ebay, I would agree that SDRs are better and cheaper than ever before. However, I think the average person will struggle with using a HackRF for more complex projects. I've used URH before, and while useful, it can be intimidating for beginners.

Also, while I like the RTL-SDR (and the price tag!), you can't transmit with it. While this isn't a deal breaker to everyone, if you'd like to clone a garage door remote, for example, you need to be able to transmit. While you could use something like a raspberry pi and rpix [0], but I think it is more work than it's worth for many. Also, multiple RTL-SDRs are required for higher bandwidth applications like ASTC TV or trunked radios.

With the flipper, I think the main draw for most is the point-click-done nature. Include the Android/iOS app and it makes it easy to configure on the go without a computer. The expandability is one of the main feature that will increase adoption over time compared to the HackRF+PortaPack which, from what I saw in the past, lacked longer-term support and regular updates and new features.

HackRF One is an option. There are a number of others. Legality varies by country/frequency/power level.

Can also make a Raspberry Pi act as a transmitter (https://github.com/F5OEO/rpitx), which could hit the zwave frequency but not the zigbee one. (Also, make sure to put a low pass filter on it.)

The warning at https://github.com/F5OEO/rpitx#hardware suggests a bandpass filter will be needed but has no additional info. https://github.com/F5OEO/rpitx/issues/40 looked promising but is closed.

On a similar path, you might look at: rpitx

RF transmitter for Raspberry Pi With this project you can turn your Raspberry Pi into an RF transmitter with only a filter to avoid interferences.

RPITX is the spiritual successor of your project!

And it does work with nearly every RPi.

And unlike only doing FM (97MHz-108MHz), it can emit from an IQ datastream from 10KHz to 1.5GHz.

Hey everyone, I've recently discovered that the Raspberry Pi can act as a radio tranceiver, and am hoping to use it for security research. While projects such as rpitx act as a great tech demo, they don't offer me the modularity/parametrization I was hoping for. Ideally the end state for this would be a cheaper/less effective HackRF.

The RPITX project supposedly can generate signals up to 1.5GHz with an unmodified Pi, though, which is interesting... a true spectrum analyzer needs a receiver end, though.

Seems like there is at least a bit of interest [1] to convert lirc definitions [2], which is great, because there are so many of them. There even is a definition for my about 30 years old hifi! A really nice hack I saw is to send the code via something that reads lirc and capture it with a flipper in learning mode [3].

If you're actually looking as bruteforcing IR, have a look at an example .IR file from the IRDB. They are just text files with a bunch of values in them. It would be pretty trivial to create a Python script that generates every possible IR signal, then upload that .IR file to the Flipper, although I would expect it would take a long time to run.

If you're feeling generous, capture codes from remotes and submit them to https://github.com/UberGuidoZ/Flipper or https://github.com/Lucaslhm/Flipper-IRDB

Manufacturers will sometimes use the same IR codes across models. Try one of the files for Telefunken TVs in the IR database on Github - https://github.com/Lucaslhm/Flipper-IRDB/tree/main/TVs/Telefunken

As you noted, the universal remote can turn your TV on and off, so it s manufacturer, you can try signals from the flipper IRDB and see if any of them work. From there, you can cobble together a remote that hopefully covers most or all of your device's functions.

Here's the Flipper Zero IR config for the CLD-99 remote I created. It's not perfect but it's better than having no remote or having to walk across the room to press buttons on the device.
