We are working with the WiFi/BT combo module WM-BG-MR-03 of USI
We have interfaced this module through UART to the OMAP3530 Processor.
Currently we are facing an issue with the bluetooth interface.
The device is not responding for BCSP/CSR protocol of bluz
we probe the Serial line between the processor and the BT module, we
signal toggling in the line. Hence we feel that the initialisation sequence
is issued by the processor, but the BT module is not responding to that.
We are updating the firmware using sd8688_helper.bin and sd8688.bin.
running the below commands.
#hciattach ttyS1 bcsp 115200
#hciattach ttyS1 csr 115200
#hciattach ttyS1 any
Both the results for above commands is
"Initialisation timed out".
Please let me know have any used this chip ?
Please support us and also help us to debug.
