hi Venu,
1 . When we issue command
#hciattach ttyS1 bcsp 115200
we are able to see the tx line toggling from the processor .
2. But when we issue command
#hciattach ttyS1 any
hci0 device is created.
But no toggling in tx line when we issue command "hciconfig hci0 up"
we dont have any debug interface.
-Regards,
Shankar
Have seen what happening over the air, when this happens... I mean ask
from UART via HCI, is even reaching Link manager/baseband ?
Do u have interface such JTAG to debug...
Cheers,
Venu

Hi all,
We are working with the WiFi/BT combo module WM-BG-MR-03 of USI
Technologies.
We have interfaced the Bluetooth module through UART to the OMAP3530
Processor and wifi through SDIO interface. Currently we are facing an
issue with the bluetooth interface.
The device is not responding for BCSP/CSR protocol of bluez utility
(hciattach). When
we probe the Serial line between the processor and the BT module, we
observed
signal toggling in the tx line. Hence we feel that the initialisation
sequence is issued by the processor, but the BT module is not
responding to that.
running the below commands.
#hciattach ttyS1 bcsp 115200
Gives output "Initialisation timed out"and we can see toggling
data in tx
line
#hciattach ttyS1 any
output:dev0 is created and we couldnt see any data in tx line when we
isssue the command hciconfig hci0 up.
"Please let me know have any one used this chip ?
has any one faced this problem?Please give ur suggestion.
Please also help us to debug.
regards
Shankar
