Flipper’s firmware is deeply under development, new features and protocols added everyday. We need your help to analyze and collect new protocols. Please follow this guide to create a report of your unsuported remote. Your report will help developers to implement new Sub-GHz protocols.
По вопросу “Flipper не видит мой брелок”
Different wireless keyfobs operates on various radio frequencies depends on your country, and system manufacturer. For example it can be:
- 315 MHz
- 318 MHz
- 433.4 MHz
- 433.92 MHz
- 434.42 MHz
- 868.36 MHz
- … etc
To analyze your remote, you need to know the exact frequency it operates and configure Flipper Zero on this freq.
Not only frequency but modulation may be different. Keyfobs operates on the same frequency may be completely different in modulation. For example:
- Amplitude-shift Keying — ASK (OOK, AM). Simple modulation, no need additional configuration to decode the signal.
- Frequency-shift Keying — 2-FSK (FM). Tricky modulation, you need to know frequency deviation config to decode signal.
- … etc
To capture your signal, you need to configure the correct modulation settings on Flipper Zero. Because Flipper is not SDR, you need to configure the right modulation before capturing the signal, otherwise, you will not receive the correct data. You cannot change the modulation on capturing signal as you can do on SDR.
When we know the physical characteristics of your signal (Freq, and Modulation), the next step is to find out the logical level — digital protocol. There are hundreds of digital radio protocols. Sub-GHz digital radio protocols can be divided into two major types:
- Static codes — every time you press the button on your remote, it sends the same code
- Dynamic (Rolling) codes — different codes on every button press, for security reasons
Flipper Zero supports lots of Static and Rolling codes. Flipper can hijack and decode many of Rolling codes, but for security reasons, we prevent saving the decoded dynamics codes in stock firmware.
To capture and decode protocol that Flipper Zero understand, go to
Sub-GHz —> Read. But not every protocol can be captured this way, for protocols Flipper do not know, you can use
When Flipper doesn’t know your protocol yet, you can capture it using
Read RAW feature. This feature will save raw data without decoding and parsing it. You can analyze this data on PC, send it to developers and replay captured signal, But keep in mind, that you still need to configure the right Freq/Modulation for capturing correct data.
For adding new protocols, we need your help. Please collect this data and create a new topic on this forum.
Create a new topic in Sub-GHz section. Name the subject with the name of your wireless system brand name.
Find the exact frequency of your system
Attach the high resolution photo of your remote, to make FCC ID can be seen clearly.
[Optional] Taerdown photo of PCB and chips will be useful too. But no need to damage your main keyfobs for this.
If Flipper Zero supports your freqency in default configuration, and your signal is ASK (OOK, AM) modulation, please capture the RAW signa on Flipper. Press each button on your remote for 10 times, and record the RAW signal of each button pressed on a different file and attach this files to your topic on forum.
[Optional] Your remote may have the function of binding it to the new system (Master Code send). Record this signal too, if you know how.
If frequency or modulation is cannot be configured on Flipper Zero out of the box, for example 2-FSK(FM), please record your signal using SDR. For example, using RTL-SDR and Universal Radio Hacker. Save signal and attach it to forum topic.
