Servo Gripper Not Working or Software Freezes in v6.0

Symptoms:

• Your servo gripper works in software v5.1 but not in v6.0.
• The software freezes or hangs when trying to use the gripper.
• You see errors related to the Arduino Nano or communications.

Solution:
This issue is almost always caused by an incorrect bootloader setting on your Arduino Nano or an outdated sketch. Follow these steps to resolve it:

1. Upload the Correct Sketch: Ensure you have the latest Arduino Nano sketch (Ver 1.3 or higher) uploaded to your board. You can download the latest files from our Download Page.
2. Select the Right Bootloader: During upload in the Arduino IDE (Integrated Development Environment), you must select the “Old Bootloader” option for the Nano to communicate correctly with the v6.0 software.
   • Board: “Arduino Nano”
   • Processor: “ATmega328P”
   • Bootloader: “Old Bootloader”
3. Check Your Connections:
   • Verify the servo gripper is connected to pin A0 on the Nano.
   • Restart the software and look for the message: “COMMUNICATIONS STARTED WITH ARDUINO IO BOARD” in the console. If you don’t see it, press the “Set Com IO Board” button in the software.

Why this happens:
The v6.0 software uses a different communication protocol that requires the Arduino Nano to be using the older bootloader for reliable operation.
