Hi Vitaly,
2010/12/3 Vitaly Wool <vitalywool@gmail.com>:
What will be in the protocol file, i.e. the same level as hci_h4.c,
hci_bcsp.c, etc, will be to ~80% vendor specific. The only H4 channels
that are in a standardized specification are the Bluetooth channels
1-4. Other channels such as FM and GPS are vendor specific. I've seen
that for example TI has the same channels for FM and GPS, but these
channels, 8 and 9, are in no way standardized. The CG2900 also carries
a number of other channels, such as debug and device channels, which
I'm pretty sure is individual for this chip.
This identification of the channels is also only one function, even
though it is an important function. There are also a lot of other code
regarding baud rate settings, low power handling, etc that I'm
positive will not apply to chips of other vendors. It is of course
possible that other chips from ST-Ericsson, current and future, will
be able to reuse this file, but as I said I doubt that other vendors
might be able to use it.
I'm not certain what you mean. We are modifying the line discipline a
bit, but the only thing we have needed to do with existing protocol
drivers has been to add a boolean parameter for the protocol settings
(so they will register to the Bluetooth stack). I don't see why we
should create a new line discipline driver and then move the existing
protocol drivers to this.
