Re: [Bluez-users] How to use Bluez with CSR chip ?

[hong zhang <henryzhang62@yahoo.com>]

Raymond,

I have a few questions.

1. Do you use CSR bleutooth stack from CSR?
2. If you use Bluez, you must use bluetooth stack 
   comes with kernel.
3. How is CSR chip initialized? by eeprom?


I believe you use CSR stack then you cannot use Bluez
utilities.
