Follow the steps below to enable or disable Bluetooth Low Energy (BLE):

1. Start the BPM (Brother Printer Management Tool).
   You can download the BPM from the [Downloads] section of this website.
   • For RJ-2035B / 3035B, TJ-4420TN / 4422TN / 4520TN / 4522TN / 4620TN:
     You do not need to perform Step 2. Go to Step 3.
   • The BPM does not support the Bluetooth connection. We recommend connecting the printer to your computer via USB or Wi-Fi. For details about how to connect, see the FAQ: "How to connect the printer to your computer".
2. Check whether the Bluetooth^®/Wi-Fi® module's current firmware supports BLE:

    

   1. Select your printer and click Printer Configuration.
   
   
   2. Click the Wi-Fi tab and check the Wi-Fi version.
      - If the version is 3.7.1.0 or later, the printer can already use BLE. Go to Step 3.
      - If the version is 3.5.1.1, update the Bluetooth/Wi-Fi module's firmware. See "Update the Bluetooth/Wi-Fi module's firmware to use Bluetooth Low Energy (BLE)".

      For the following models, make sure you use the correct firmware version:

      Model	Firmware Version
      TD-4650TNWB / 4750TNWB / 4650TNWBR / 4750TNWBR	V1.04.S18 or later
      RJ-2055WB / 3055WB	B1.00.Q28 or later

3. Select your printer and click Command Tool.


4. Type the following commands and press the Enter key, and then click Send.

   If you fail to press the Enter key before clicking Send, the commands will not be executed.
