Update Process
Step 1: Check for Updates

DFU Mode (Device Firmware Update)
When updating, the device enters a special DFU Mode:
- Display shows "Updating FW / Please wait / Do not power off"
- Device advertises as "DfuTarg" over Bluetooth
- Normal operation is suspended during update
DFU Mode Timeout
If no update is received within 2 minutes, the device will automatically exit DFU mode and restart normally.
This safety feature ensures your device won't get stuck if:
- Bluetooth connection is lost
- Update is cancelled
- Phone goes out of range
Troubleshooting
Possible Causes:
- Bluetooth connection interrupted
- Phone went out of range
- Low battery on device or phone
Solutions:
- Wait 2 minutes for automatic DFU timeout
- Device will restart and return to normal operation
- Charge device to at least 50%
- Move closer to the device
- Try the update again
What to do:
- Wait 2 minutes - device will auto-restart
- If still stuck, perform a hard reset:
- Hold both side buttons for 10 seconds
- Contact support if issue persists
This is normal during updates.
"DfuTarg" is the device name when in firmware update mode. After the update completes (or times out after 2 minutes), it will return to "BeatBuddy".
Possible Causes:
- Weak Bluetooth signal
- App permissions issue
- Device not paired properly
Solutions:
- Ensure Bluetooth is enabled
- Grant all requested app permissions
- Unpair and re-pair the device
- Restart the app and try again
Manual Update via CLI
For developers and advanced users, firmware can also be updated using the command-line interface:
# From the dfu/manager directory
make scan # Find the device
make dfu # Enter DFU mode
make upload # Upload firmware package
CLI tools are available in the BeatBuddy Firmware repository.
