# Using the Web Updater to update the Bluetooth Module

## Bluetooth Module Firmware Recovery (Version shows **0.0.0**)
If your Bluetooth Module is not functioning and the Bluetooth version displays **0.0.0**, the module firmware may need to be reinstalled.


### Before You Begin
* You will need to **remove the backplate** to access the **internal USB-C port** used for updating the Bluetooth Module.

## Firmware Update Steps
1. Open the Bluetooth firmware web updater:
👉 https://bluetooth-module-updater.morningstar.io/

|| ⚠️ The web updater may not work reliably with native USB 3.0 ports. If your computer only has USB 3.0 ports, you can use a USB 2.0 dongle or hub connected to the USB 3.0 port. This is not necessary - only something to try if you are not able to connect.


2. Download the latest Bluetooth firmware from https://firmware.morningstar.io

3. Connect the internal USB-C port to your computer and click **Connect to Device** on the web updater.

|| If the default 921600 baud rate does not connect, try refreshing the app and then select the 115200 baud rate.

4. Once connected successfully:
    * Select the firmware file you downloaded
    * Click **Upload** to flash the firmware to the Bluetooth Module

5. Wait for the process to complete, then disconnect and reassemble the unit.



## Troubleshooting connection issues with the Updater
If the web updater fails to connect, you may need to use a pair of metal tweezers, for example, to short 2 points on the board before connecting.

1. The symptom is the failure to connect to the Bluetooth module with the error below

2. The part C10 needs to be shorted by a pair of metal tweezers or anything metal.

3. While the points are being shorted, click on Connect in the updater and the connection should be successful.
