CSR Bluetooth Code 43 error

Do you understand the CSR Bluetooth Code 43 error? I got this Bluetooth thingy, the CSR Bluetooth USB 5.0. At first, it worked fine, but then it suddenly stopped after an update. Whenever I plug in the USB, it shows up in the device manager, but then a few seconds later, a warning pops up saying ‘Code 43’. I tried deleting all the drivers, but it didn’t help.

In the Services window, find the service named “Bluetooth Support Service.”

Restart the Service:

  • Right-click on “Bluetooth Support Service.”
