Hi,
Thanks for your reply
I am looking for the original firmware that came with the board during the time of purchase. The one that we could attach to bluez via hci

Unfortunately there is no way to retain that firmware. But you can do recovery procedure and configure the board to receive HCI commands. Please check https://community.cypress.com/t5/Resource-Library/Running-BlueZ-on-CY-Part/ta-p/246050

Hi Team,
Thanks for your reply.
After following all the steps, as mentioned on the blog still HCI is not working out.
This hci1 BD address is 00:00:00:00:00:00. Which seems very unreliable.
Please help me to solve this issue.
Thanks a lot

Have you programmed the board sing an empty application first?
Have you tried resetting the board as mentioned in the blog? Is it not working?

Hi @Vaibhav330900 ,
As mentioned in the KBA above (recommended to download an empty Application), You should first program the device with an empty application, not the hello sensor project.
Your .c file should not contain any infromation, keep only source file name in makefile. No wiced_bt_cfg.c file required. Just the source .c and makefile should work. First recover the board using recovery procedure and then program your board with attached empty application.
Ideally, you should be able to setup communication using the procedure mentioned in the KBA.

Your Make Target is incorrect. Please follow the standard format-
<app_name>-<board name> download
ex. empty-CYW920735Q60EVB_01 download
Make sure you dont have HCI COM port open anywhere else.
More details on how to program the board can be found in kit user guide.
