-- **protocol and its data**: contains protocol name and its specific data, such as key, bit length, etc., or RAW data

 Flipper's SubGhz subsystem uses presets to configure the radio transceiver. Presets are used to configure modulation, bandwidth, filters, etc. There are several presets available in stock firmware, and there is a way to create custom presets. See [SubGhz Presets](#adding-a-custom-preset) for more details.

 Long payload not fitting into internal memory buffer and consisting of short duration timings (< 10us) may not be read fast enough from the SD card. That might cause the signal transmission to stop before reaching the end of the payload. Ensure that your SD Card has good performance before transmitting long or complex RAW payloads.
 
+### BIN_RAW Files
+
+BinRAW `.sub` files and `RAW` files both contain data that has not been decoded by any protocol. However, unlike `RAW`, `BinRAW` files only record a useful repeating sequence of durations with a restored byte transfer rate and without broadcast noise. These files can emulate nearly all static protocols, whether Flipper knows them or not.
+
+- Usually, you have to receive the signal a little longer so that Flipper accumulates sufficient data for correct analysis.
+
+For `BinRAW` files, the following parameters are required and must be aligned to the left:
+
+- **Protocol**, must be `BinRAW`.
+- **Bit**, is the length of the payload of the entire file, in bits (max 4096).
+- **TE**, is the quantization interval, in us.
+- **Bit_RAW**, is the length of the payload in the next Data_RAW parameter, in bits.
+- **Data_RAW**, is an encoded sequence of durations, where each bit in the sequence encodes one TE interval: 1 - high level (there is a carrier), 0 - low (no carrier).
+    For example, TE=100, Bit_RAW=8, Data_RAW=0x37 => 0b00110111, that is, `-200 200 -100 300` will be transmitted.
+    When sending uploads, `Bit_RAW` and `Data_RAW` form a repeating block. Several such blocks are necessary if you want to send different sequences sequentially. However, usually, there will be only one block.
