Request
| Index Word | Description |
|---|---|
| 0 | Header code [0x00200102] |
| 1 | u32 inputsize |
| 2 | u32 outputsize |
| 3-4 | u64 microseconds value, timing related. The value passed to the internal send-cmd func is basically: "in64 / 1000000". |
| 5 | Descriptor for static buffer (id 0) |
| 6 | Input buffer address with static_buf_id=0 |
The handler for this IPC command expects the following 0x100-bytes after the beginning of the above command buffer:
| Index Word | Description |
|---|---|
| 0 | Descriptor for static buffer (id 0) |
| 1 | Output buffer address |
Response
| Index Word | Description |
|---|---|
| 0 | Header code |
| 1 | Result code |
| 2 | u32 actual_output_size |
| 3 | Descriptor for static buffer (id 0) |
| 4 | Output data pointer with static_buf_id=0 |
Description
This sends a raw NFC command to the tag. First byte in the inbuf is the command, followed by any parameters for the command if required. The outbuf contains the command response.
outputsize value 0x800 will be used when it's >=0x800. An error will be returned if actual_output_size is larger than outputsize. This can only be used when the TagState is 3.
