Hello,
I've been trying to sort out my bluetooth connection for some time already. Not much luck:
1. An ASUS adapter - theoretically works, but produces pronounced distortions while in a call (I've started a separate thread about it, here).
Full specification:
BCM20702A0:
Product ID: 0x17cb
Vendor ID: 0x0b05 (ASUSTek Computer Inc.)
Version: 1.12
Serial Number: 5CF370A6C81F
Speed: Up to 12Mb/sec
Manufacturer: Broadcom Corp
Location ID: 0x14100000 / 4
Current Available (mA): 500
Current Required (mA): 100
Extra Operating Current (mA): 0
2. A CSR 5.0 adapter - is not recognized by the Raspberry Pi (clicking on "Menu" --> "Preferences" --> "Bluetooth Manager") does nothing. The manager does not start and my iPhone does not discover the adapter.
Full specification:
CSR8510 A10:
Product ID: 0x0001
Vendor ID: 0x0a12 (Cambridge Silicon Radio Ltd.)
Version: 25.20
Speed: Up to 12Mb/sec
Location ID: 0x14200000 / 7
Current Available (mA): 500
Current Required (mA): 100
Extra Operating Current (mA): 0
3. A CSR 4.0 adapter - exactly the same results as for CSR 5.0. The mystery became quickly solved by checking the full specification (using a Macbook):
CSR8510 A10:
Product ID: 0x0001
Vendor ID: 0x0a12 (Cambridge Silicon Radio Ltd.)
Version: 25.20
Speed: Up to 12Mb/sec
Location ID: 0x14200000 / 8
Current Available (mA): 500
Current Required (mA): 100
Extra Operating Current (mA): 0
It seems like 2. and 3. are exactly the same chip - despite being sold as 4.0 and 5.0. Photo:
CSR 4.0 and CSR 5.0
In case anyone wonders if the full specification is not a mistake: no, I have plugged them both simultaneously and got two identical readings in the System Report under USB tab on a Macbook. I recon that the CSR 4.0 adapter that I have is actually the 5.0 in a different outer shell. I hope it is not the other way around.
QUESTIONS:
1. Does anyone know what is the full specification of a fully supported bluetooth adapter (a CSR 4.0, I pressume)?
Please be so kind and paste it in comments I need to know what I am dealing here with: two 4.0s or two 5.0s?
2. Does anyone have an adapter that works and is fully tested with the OpenAuto Pro environment for sale? I will gladly buy. This shoot-and-miss bluetooth competition has already been a month...!
