| ieee802154 wpan radio protocol over USB |
| |
| Overview |
| ======== |
| |
| The document describes protocol between 802.15.4 physical radio and Linux |
| kernel driver over USB. Protocol is based on atusb Linux driver protocol |
| found inside Linux kernel: drivers/net/ieee802154/atusb.h |
| |
| Packet structure |
| ================ |
| |
| Command opcodes are inside bRequest field. bRequest and wIndex are one octet |
| long. |
| |
