+# reTerminal DM4 Buzzer Control - Jira Summary
+
+## Summary
+
+Implemented buzzer control functionality for reTerminal DM4 device with test scripts and documentation.
+
+## Device Information
+
+- **Model:** reTerminal DM4 (Raspberry Pi CM4)
+- **Buzzer Location:** Bottom right corner of screen
+- **Control Path:** `/sys/class/leds/usr-buzzer/brightness`
+- **Control Method:** Linux LED subsystem (on/off only)
+
+## Implementation
+
+### Test Scripts Created
+
+1. **Bash Test Script** (`test_buzzer.sh`)
+   - Location: `/home/pi/buzzer/test_buzzer.sh` on device
+   - Tests: 8 different buzzer patterns (single, double, triple, long, rapid, slow, success, error)
+   - Usage: `ssh guard "/home/pi/buzzer/test_buzzer.sh"` or `/home/pi/buzzer/test_buzzer.sh`
+
+2. **Python Test Script** (`test_buzzer.py`)
+   - Location: `/home/pi/buzzer/test_buzzer.py` on device
+   - Same test patterns as bash script
+   - Usage: `ssh guard "python3 /home/pi/buzzer/test_buzzer.py"` or `python3 /home/pi/buzzer/test_buzzer.py`
+
+### Basic Control Commands
+
+```bash
+# Turn ON
+echo 1 | sudo tee /sys/class/leds/usr-buzzer/brightness
+
+# Turn OFF
+echo 0 | sudo tee /sys/class/leds/usr-buzzer/brightness
+
+# Check Status
+cat /sys/class/leds/usr-buzzer/brightness  # 0=OFF, 1/255=ON
+```
+
+### Python Control Example
+
+```python
+import subprocess
+import time
+
+BUZZER = '/sys/class/leds/usr-buzzer/brightness'
+
+def beep(duration=0.2):
+    subprocess.run(['sudo', 'tee', BUZZER], input='1', text=True)
+    time.sleep(duration)
+    subprocess.run(['sudo', 'tee', BUZZER], input='0', text=True)
+```
+
+## Common Use Cases
+
+- **Success Alert:** 2 short beeps
+- **Error Alert:** 3 fast beeps
+- **Notification:** 1 short beep
+- **Warning:** 1 long beep
+
+## Requirements
+
+- `sudo` privileges required
+- Test scripts available on device at `/tmp/`
+- Buzzer is simple on/off (no volume/frequency control)
+
+## Documentation
+
+- **Quick Reference:** `BUZZER-CONTROL.md` - Concise guide with commands and test script references
+- **Detailed Guide:** `BUZZER-CONTROL-SIMPLE.md` - Comprehensive documentation
+- **Flask API:** `FLASK-BUZZER-CONTROL.md` - Web API implementation
+
+## Testing
+
+Both test scripts have been uploaded to the device and verified working. Scripts test:
+- Single beep patterns
+- Multiple beep patterns
+- Different timing intervals
+- Common alert patterns (success, error)
+
+## Status
+
+✅ **Complete** - Test scripts created, uploaded to device, and documentation provided.
