- `monitor status` - Show monitor status - `monitor status` - Show monitor status
### SD Card Commands ### SD Card Commands
- `sdcard status` - Show CD, mounted, capacity, fiwi-telemetry info Telemetry from monitor mode is stored in `fiwi-telemetry` (NDJSON, appended each flush). Use SD commands to inspect or transfer it.
- `sdcard status` - Show CD, mounted, capacity, and fiwi-telemetry file info
- `sdcard list [path]` - List files (path optional, default root) - `sdcard list [path]` - List files (path optional, default root)
- `sdcard read <file>` - Read and print file (e.g. `sdcard read fiwi-telemetry`)
- `sdcard write <file> <text>` - Write text to file - `sdcard write <file> <text>` - Write text to file
- `sdcard read <file>` - Read and print file - `sdcard send <file>` - Stream file over serial (use `tools/sdcard_recv.py`)
- `sdcard send <file>` - Stream file over serial (use tools/sdcard_recv.py)
- `sdcard delete <file>` - Delete a file - `sdcard delete <file>` - Delete a file
**Example (telemetry capture):**
```text
monitor start 6
sdcard status
sdcard list
sdcard read fiwi-telemetry
```
