This commit refactors the CC1101 driver's read interface to comply with
the standard NuttX wireless character driver API and introduces extended
hardware operation modes.
- Migrate `cc1101_file_read` to accept and populate the standard
`struct wlioc_rx_hdr_s` instead of returning raw byte arrays.
- Implement `cc1101_calc_rssi_dbm_x100` to preserve the hardware's
0.5 dBm RSSI precision when scaling to 1/100 dBm units, eliminating
the integer truncation loss present in the legacy calculation.
- Add `CC1101IOC_SETOPMODE` and `CC1101IOC_GETOPMODE` IOCTLs.
- Introduce four RF operation modes (`enum cc1101_opmode_e`):
1. NORMAL: Standard packet mode with hardware filtering.
2. PROMISCUOUS: Packet mode bypassing address filtering and retaining
packets with CRC errors.
3. SYNC_SERIAL: Bypasses FIFO, routes clock and data to GDO0/GDO2.
4. ASYNC_SERIAL: Bypasses FIFO, routes async data to GDO2.
- Fix the `GS2200M_FIRST` IOCTL block offset in `wireless/ioctl.h` and
allocate a dedicated IOCTL block for CC1101.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
