Cambridge Silicon Radio Ltd Bluetooth Dongle Mac: A Troublesome Connection

The quest for a reliable Bluetooth connection can be frustrating, especially when dealing with multiple adapters and devices. As someone who has struggled with connectivity issues, I can attest that it's essential to understand the specifications of your Bluetooth adapter to ensure seamless communication.

In my case, I have two Cambridge Silicon Radio Ltd (CSR) adapters, labeled as both 4.0 and 5.0, but with identical readings on my MacBook under the USB tab in System Report. This suggests that they are actually the same chip, despite being marketed differently. The vendor ID for these adapters is 0x0a12, which confirms their identity.

I have tried using both adapters with my OpenAuto Pro setup, but unfortunately, they are not visible to my iPhone or a fully functional Xiaomi Mi A2 Lite running pure Android 10. This lack of visibility is also evident when attempting to enable Bluetooth on my Raspberry Pi OS device; the app 'Bluetooth Manager' fails to launch.

The ASUS/Broadcom adapter, on the other hand, works theoretically but produces noticeable distortions during calls. I have started a separate thread about this issue elsewhere.

If you are experiencing similar problems with your CSR adapters or other Bluetooth devices, it's crucial to understand that not all adapters work seamlessly with OpenAuto Pro. The mystery of why some adapters don't work together can be solved by checking the full specification of each device using a MacBook or other compatible device.

In conclusion, while I have encountered challenges with my Cambridge Silicon Radio Ltd Bluetooth dongles, understanding their specifications has helped me better comprehend the issues at hand. If you are struggling with Bluetooth connectivity, it's essential to research and test your adapters before investing in new ones.
