* [Bluez-devel] LMX9830 driver @ 2007-05-10 7:44 David Beamonte 2007-05-10 9:34 ` Marcel Holtmann 0 siblings, 1 reply; 6+ messages in thread From: David Beamonte @ 2007-05-10 7:44 UTC (permalink / raw) To: bluez-devel Hi, We have included a National LMX9830 module in a new design. The communication between the chip and the microprocessor is via UART and we have also connected the audio channels of the chip to the processor, so that we can use the SCO link. It's the first time we use bluetooth modules in our designs, and so, we are open to any kind of suggestion on how to work on this. At first sight, it seems that we should use the UART(H4) driver, but we are not really sure if the commands to communicate to the chip are standard or not. I think that we will probably need to develop some kind of a driver. Please, we would really appreciate some help about how to start working with this chip.

However you might need to adapt hciattach for the module initialization.

I understand from your words that this is the standard way to communicate and that all devices have the same set of commands. Anyway, I will check what you mention about hciattach. Is there any kind of documentation on how to do this, or I must dig into the code?

The communicating with the chip is via an specific set of commands, and so, the HCI drivers and hciattach are not suitable for us. We guess that we must develop our own driver that substitutes HCI driver, but we are not sure where we should start working. I would like to know if there's any effort done in this way in the BlueZ development. We are open to any suggestion or hint that can gives us some light to this matter.
