|
|
|
|
|
|
|
|
## Features
|
|
- ESP32-S3 based anchor and tag devices
|
|
- Real-time distance measurement with <10cm accuracy
|
|
- OLED display for status and measurements
|
|
- Multiple tag support (up to 64 tags)
|
|
- 6.8Mbps communication rate
|
|
- Complete AT command implementation
|
|
- Position calculation with trilateration
|
|
- Anchor auto-positioning system
|
|
- Real-time positioning with USB data logging
|
|
|
|
|
|
|
|
**Hardware:** [Makerfabs MaUWB ESP32-S3 UWB Module](https://www.makerfabs.com/mauwb-esp32s3-uwb-module.html) with SSD1306 OLED displays
|
|
|
|
## Environments
|
|
- `anchor`: Base station for positioning
|
|
- `tag`: Mobile device for tracking (ID 1)
|
|
- `tag2`: Mobile device for tracking (ID 2)
|
|
|
|
## Build & Upload
|
|
```bash
|
|
# Build specific environment
|
|
pio run -e anchor
|
|
pio run -e tag
|
|
|
|
# Upload to device
|
|
pio run -e tag -t upload
|
|
|
|
# Monitor serial output
|
|
pio device monitor
|
|
```
|
|
|
|
## AT Command Support
|
|
|
|
Complete implementation of all AT commands from the official manual:
|
|
|
|
### Basic Commands
|
|
- `AT?` - Test connection
|
|
- `AT+GETVER?` - Get firmware version
|
|
- `AT+RESTART` - Restart module
|
|
- `AT+RESTORE` - Factory reset
|
|
- `AT+SAVE` - Save configuration
|
|
|
|
### Configuration
|
|
- `AT+SETCFG` / `AT+GETCFG?` - Device configuration
|
|
- `AT+SETANT` / `AT+GETANT?` - Antenna delay calibration
|
|
- `AT+SETCAP` / `AT+GETCAP?` - System capacity settings
|
|
- `AT+SETRPT` / `AT+GETRPT?` - Auto-reporting control
|
|
|
|
### Network & Power
|
|
- `AT+SETPAN` / `AT+GETPAN?` - Network ID configuration
|
|
- `AT+SETPOW` / `AT+GETPOW?` - Transmission power control
|
|
- `AT+SLEEP` - Sleep mode for battery conservation
|
|
|
|
### Data Communication
|
|
- `AT+DATA` / `AT+RDATA` - Custom data transmission
|
|
- Real-time range reporting via `AT+RANGE` parsing
|
|
|
|

|
|
- **Anchor position management** for auto-positioning
|
|
- **Distance filtering** for improved accuracy
|
|
- **Backward compatibility** with existing code
|
|
|
|
## Configuration
|
|
- **Network ID**: 1234 (configurable via AT+SETPAN)
|
|
- **Baud Rate**: 115200
|
|
- **Communication**: 6.8Mbps (AT+SETCFG parameter)
|
|
- **Range filtering**: Enabled for accuracy
|
|
- **Refresh Rate**: 10Hz (configurable via AT+SETCAP)
|
|
- **Max Anchors**: Unlimited (tags connect to 8 closest)
|
|
- **Max Tags**: 64 per network
|
