Can't connect to BetaflightUpdated 6 months ago

If you’re having trouble connecting your flight controller to Betaflight, the issue is often related to missing or incorrect drivers. Follow these steps to resolve the issue, depending on your chip version.

Step 1: Identify Your Chip (AT32 or STM32)

AT32 (Artery Chip):

• These flight controllers are becoming popular due to their affordability. However, they require manual driver installation, as the ImpulseRC Driver Fixer doesn't support AT32. The flight controller name contains ATF.

STM32:

• This chip is the most common and usually works well with the ImpulseRC Driver Fixer. The flight controller name contains F4, F7 or H7.

Step 2: Resolving STM32 Driver Issues (Automatic Fix)

If your STM32-based controller isn't detected in Betaflight, follow these steps:

1. Download the ImpulseRC Driver Fixer:

   • Download the tool from here.
   • Run the tool while your controller is connected to your computer.
   • The tool will automatically attempt to fix any driver issues related to STM32 flight controllers.

2. Ensure You Have the Correct COM Port Drivers:

   • STM32 flight controllers typically require virtual COM port drivers, which are usually installed by default. If not, they can be downloaded from the STM website.

Step 3: Resolving AT32 Driver Issues (Manual Fix)

For AT32 controllers, drivers must be installed manually. Follow these steps to ensure proper installation:

1. Download the AT32 Virtual COM Port Driver:

   • Go to the Artery AT32F435 MCU page.
   • Download and install the Virtual COM Port Driver to enable communication between your PC and the flight controller.
   • Restart your computer after installation.

2. Install DFU Drivers for Firmware Flashing:

   • To enable DFU mode (Device Firmware Update) for flashing firmware, download the Artery ISP Programmer from the same page.
   • Install the software and restart your computer.

3. Check Device Manager:

   • After installing the drivers, connect your AT32 controller and open Device Manager (Windows key + X > Device Manager).
   • You should see the controller listed under Ports (COM & LPT) or Universal Serial Bus Devices.

4. Test in Betaflight:

   • Open Betaflight and try connecting your flight controller. It should now be recognized if the drivers are correctly installed.

Step 4: Additional Troubleshooting

• Try a Different USB Cable: Sometimes connection issues are related to faulty cables, especially if they’re charge-only.
• Reinstall Betaflight: If driver issues persist, reinstalling Betaflight can also resolve connection problems.
