Re: [bluetooth] to close RF interface

[Jamil Khatib <jamilkhatib75@yahoo.com>]

For Synt_on I think it can be handled by the bridge
that is when Tx is enabled from Baseband the bridge
should turn Synt_on then apply Tx enable to the RF. We
should not care about it in the Baseband.

I think the same applies to PHD_off 
Anyhow are these signals available on devices other
than the Ericsson's?
