Most of our current AudioB plus Bluetooth modules and Bluetooth amplifier boards with TWS firmware are set by default to enter pairing mode automatically after powering on. This allows phones or other devices to search for and connect to the device directly.
If you do not want your Bluetooth device to be discoverable by others, or if you prefer to only enter pairing mode when needed (by pressing a button), this guide will walk you through the process.
Based on CSR8635
Hardware and Software required:
- TC2050-IDC-NL 10-Pin No-Legs Cable Kit
- CSR USB-SPI programmer
- Download CSRXX_ROM_ConfigTool_3.0.56 and install it
Step 1:
Download CSRXX_ROM_ConfigTool_3.0.56 and install it.
Connect the CSR USB-SPI programmer to the TC2050-IDC-NL 10-Pin No-Legs Cable Kit, then connect the programmer to the PC using a Mini USB cable. Windows will automatically detect the device and install the drivers.
Step2:
Connect the TC2050-IDC-NL connector to the programming port of the AudioB Plus or Bluetooth amplifier board. Align the steel positioning pin with the PCB hole, then press down gently to engage the spring pins. Ensure the first 6 pins make good contact with the pads. The blue and red LEDs will flash alternately.
Step3:
Run the Config Tool and click Open from Devic, make sure the platform is CSR8635, then continue.
Step4:
Click “User Events”, and you will see three "Enter Pairing Mode" events in the red box (with index numbers 2, 3, and 4).
If you simply want the device not to enter pairing mode automatically after each power-on, click “Remove” for each of these three events.
If you want the device not to enter pairing mode automatically after power-on, but still allow pairing by double-pressing a button, you can:
- Delete the events with index numbers 2 and 4
- Change the Button setting of event 3 to DOUBLE.
After this configuration, you can double-press the Play/Pause button whenever you want the module to enter pairing mode.
Step5:
Click Write Device to write the modified parameters into the Bluetooth module.
Then disconnect the module from the CSR USB-SPI programmer.
Based on QCC3005,QCC3007 and QCC3008
Hardware and Software Required:
- Tag-Connect line Kit
- CSR USB-SPI programmer
- Download ADK_QCC300x.WIN.1.0.167 and install it
Step 1:
Download ADK_QCC300x.WIN.1.0.167 and install it.
Connect the CSR USB-SPI programmer and the TC2050-IDC-NL 10-Pin No-Legs Cable Kit, then connect the programmer to the PC using a Mini USB cable. Windows will automatically detect the device and install the drivers.
Step2:
Connect the TC2050-IDC-NL connector to the programming port of the AudioB Plus module or Bluetooth amplifier board. Align the steel positioning pin with the PCB alignment hole, then gently press down to engage the spring pins. Ensure the first 6 pins make good contact with the corresponding PCB pads. The blue LED and red LED will flash alternately if the connection is correct.
Step3:
Run the ADK Configuration Tool, and select USB SPI as the correct programmer.
Click Go Configurable, then click Read Device.
Step4:
Configuration Set -> Bluetooth-> Connection Management-> Discovery. Change Discoverable if PDL Less Than to 0.
Step5:
Configuration Set -> User Interfaces-> User Events. You will see the Enter Pairing event in the red box.
If you simply want the device not to enter pairing mode automatically after each power-on, simply click Delete to remove the event.
If you still want to enter pairing mode by double-pressing a button, configure the following:
- Check 8 for Logical Input ID(s) Assigned
- Change State Mask to 3FFE
- Change Button Timing to DOUBLE
After this configuration, you can double-press the Play/Pause button to enter pairing mode.
Step6:
After modifying all parameters, click Write Device and Go Normal. Then disconnect the CSR USB-SPI programmer.
Based on QCC3024,QCC3031 and QCC3034
Hardware and Software Required:
- Micro USB cable
- Download QCC_USBDBG_v1.0
- Download ADK_QCC512x_WIN_6_4_Installer_6_4_2_26 and install it
1. Install Qualcomm USB debug drivers (If already installed, skip this step)
Step1:
Connect the amplifier board or AudioB plus to the computer using a USB cable.
Step2:
Download QCC_USBDBG_v1.1 and unzip it, find QCC_USBDBG.exe in the folder, and run it. Click Driver Install to install Qualcomm USB debug drivers.
Step3:
Wait until Driver Install Success appears.
Then unplug and reconnect the USB cable or restart the computer to complete the driver installation. If "Driver Install Fail" appears, do not worry. Simply reconnect the USB cable or restart the computer. Open Device Manager on your computer. If you see the device shown in the red box, the USB driver has been installed successfully.
2. Install ADK_QCC512x_WIN_6_4_Installer_6_4_2_26( If already installed, skip this step)
Install ADK_QCC512x_WIN_6_4_Installer_6_4_2_26, then run the ADK Configuration Tool.
3. Modify event parameters
Step1:
Run the ADK Configuration Tool, and select the device (If no device is found, the USB driver may not have been installed successfully)
Click on Go Configurable, then click Read Device.
Step2:
Configuration Set -> Bluetooth-> Connection Management-> Discovery. Change Discoverable if PDL Less Than to 0.
Step3:
Configuration Set -> User Interfaces-> User Events. You will see the Enter Pairing event in the red box.
If you simply want the device not to enter pairing mode automatically after each power-on, click “Delete”.
If you want the device not to enter pairing mode automatically after power-on, but still be able to enter pairing mode by double-pressing a button, you can check 8 and 2 for Logical Input ID(s) Assigned, change State Mask to 3FFE, and change Button Timing to DOUBLE.
After this configuration, you can double-press the Play/Pause button to enter pairing mode.
Step4:
After all the parameters have been changed, click Write Device, then Go Normal.
