Dear Daniel, We want to share some information between wifi driver and bt driver, what rules do you recommend for the following situation ? 1. at system startup, bluetooth driver want to read some information (eg antenna settings) that generated by wifi , shall we use files or /proc/ information? 2. when user is using Bluetooth, bt driver may notify wifi driver to perform better, shall we use socket to communication?

I believe this configuration is having no effect. I tested as follows: Built kernel without rtlwifi support. Booted. Disconnected both antennas. Moved remote bluetooth device 2 metres away. Ran "hcitool scan" --> no results. Good. Connected antenna 1. Scan --> remote device can be seen Disconnected antenna 1, connected antenna 2. Scan --> remote device can be seen I then tried with CONFIG_S1_ANTENNA and then again without doing the S0/S1 antenna config at all. The results are always the same. It seems like the bluetooth interface is always using both antennas (hence it can work even if one of them is disconnected). Also, even with this antenna config in place, there is no affect on the original issue: connecting to wifi still breaks the bluetooth scan after a short while.
