No, that should be it. If the WL1271 has clocks (input reference) & the BT EN is high. It should be able to respond to commands sent over the UART. Could you confirm data was actually Tx-ed? over the UART lines? The initial baud-rate which hciattach uses is 115200 (which is also the one required by the chip)- Confirm that this is the one which is being set. > > Thanks, > Parth > > > > > > On Tue, Aug 30, 2011 at 7:31 PM, Pavan Savoy <[email protected]> wrote: >> >> On Tue, Aug 30, 2011 at 9:26 PM, parth shah <[email protected]> >> wrote: >> > Hello Friends, >> > >> > I'm using WL1271 WIFI/BT module. >> > >> > I'm getting below output while running hciattach /dev/ttymxc1 texas >> > 30000000 >> > >> > [ATH_INFO] (external/bluetooth/bluez/tools/hciattach.c) <init_uart>: >> > Serial >> > port is opened >> > [ATH_INFO] (external/bluetooth/bluez/tools/hciattach.c) <init_uart>: >> > Port >> > settings is gotten >> > [ATH_INFO] (external/bluetooth/bluez/tools/hciattach.c) <init_uart>: >> > Port >> > settings is set >> > [ATH_INFO] (external/bluetooth/bluez/tools/hciattach.c) <init_uart>: >> > Initial >> > baud rate is set >> > [ATH_INFO] (external/bluetooth/bluez/tools/hciattach.c) <init_uart>: >> > Break >> > is sent >> > Initialization timed out. >> >> What platform is this ? >> Have you powered the BT chip ?
