Firmware for Texas Instruments CC2531 Dongle to be used with this Linux kernel driver for CC2531 WPAN Adapter firmware.
Enables a CC2531 dongle to be used as a proper WPAN adapter through the Linux WPAN subsystem.
- All packets received are send to USB host.
- Transmit with optional IEEE 802.15.4 CSMA.
- Read/write all registers over USB.
- 2Mbaud 1N8 uart log output on pin P1.6
- SPI-like real time TX/RX packet sniffer output (tx: P1.3, data: P1.4, clock: P1.5)
- Supports USB Device Firmware Upgrade (with DFU bootloader)
In addition to the standard USB 2.0 control requests, the following control endpoint requests are supported:
| bmRequestType | bRequest | wValue | wIndex | Data | |
|---|---|---|---|---|---|
| Read XDATA | 0xC0 | 0x00 | Register or RAM Address | D/C | Contents of RAM or register(s) |
| Write XDATA | 0x40 | 0x01 | Register or RAM Address | D/C | Data to be written, starting at address wValue |
| Read FIFO | 0xC0 | 0x02 | FIFO Address | D/C | Contents of FIFO |
| Write FIFO | 0x40 | 0x03 | FIFO Address | D/C | Bytes to be written into specified address |
| Transmit | 0x40 | 0x04 | Non-zero: Disable CSMA, transmit immediately | D/C | IEEE 802.15.4 frame to be written to radio FIFO |
| Set CSMA parameters | 0x40 | 0x05 | (retries << 8)|(be_max << 4)|(be_min << 0) | D/C | D/C |
| DFU_DETACH | 0x21 | 0x00 | D/C | D/C | D/C |
D/C: Don't care
Endpoint 1 (Interrupt IN) sends one byte status messages to host. Transmit success (0) or failure (non-zero).
Endpoint 5 (Bulk IN) sends received IEEE 802.15.4 frames to host.
