藍牙無法正常工作。MPOW BH519A

  • September 2, 2021

我正在嘗試讓我的 MPOW BH519A 藍牙適配器工作。有類似的文章，包括關於此適配器的文章。不幸的是，我嘗試了所有這些，但沒有任何幫助。我已經測試了一些命令，例如：

  • sudo apt install blueman
  • sudo make install INTERFACE=all (MPOW Linux Driver 下載，在文件夾裡面執行這個命令)
  • sudo mv -v ~/Downloads/rtl8761b_config /usr/lib/firmware/rtl_bt/rtl8761b_config.bin
  • 快速安裝 bluez4
  • 快速安裝 bluez
  • sudo apt install bluez bluez-obexd
  • sudo apt-get install bluez-utils libopemnobex1
  • sudo apt 重新安裝 bluez
  • sudo blueman-manager

我什至無法讓 LED 執行。我設法將控制項設置為打開，但它顯示“未找到藍牙適配器”。在多次嘗試使用不同的命令後，我什至無法將控制項設置為打開。

因為我是一個完整的 Ubuntu 初學者，所以我覺得我可能有重複或忽略了一些重要的東西。

這裡有一些輸出。不幸的是，我不知道哪些資訊對您有幫助。

我在使用同一個適配器時遇到了類似的問題 - 沒有被辨識。顯然，從 MPOW 下載的驅動程序源包中的rtk_misc.c中缺少它的 USB pid 。

這是對我有用的修復：

  1. 編輯從 MPOW 下載的驅動程序包中提取rtk_misc.c的文件夾中的文件。usb/bluetooth_usb_driver我的是名為20201202_LINUX_BT_DRIVER
  2. 複製並粘貼第 311 行以添加缺少的 pid，例如
{0x2550, 0x8761, "mp_rtl8761b_fw", "rtl8761bu_fw", "rtl8761bu_config", NULL, 0}, /* MPOW BH519AB RTL8761BU only */
  1. 搜尋行讀數（最初是第 939 行）：
patch->chip_type = RTL8761BU;
  1. 在其上方添加突出顯示的 case 語句，
案例 0x8771： 
案例 0xa725： 
案例 0xa72A： 
*案例 0x2550：*
  1. 保存並重複 make install 以建構和安裝驅動程序並嘗試適配器
