Hi Cypress experts:

We have a host system zynq and want to enable BLE function with 43438/w chip to transfer data between zynq and 43438. From Wiced SDK document,

43438 does support wiced specific HCI interface to let external host talk to 43438, However, the Wiced SDK seems only has some built-in  BLE library for platform STMXXX

series and since we only need BLE to exchange some data between zynq and 43438.  Is there any way we can try?

Q1. we dont not want to use HCI host controller mode, since porting BT stack on our host is difficult, so does 43438 can be used as embeded mode? (per my understanding, talking with wiced hci interface)

Q2. If it is possible, is there any reference code i can use to replace the dependent BT library?  I means sample codes to implement wiced_bt_stack_init etc? I see some code under 43xxx_Wi-Fi\libraries\drivers\bluetooth\wiced_hci_bt/ can those code be used?

Hi xiku_4063091,

I am extremely sorry for confusion, CYW43438 cannot be used in Embedded mode. 43012 is the only combo device that supports embedded mode. All our standalone BT devices (20719, 20819, 20820 etc) supports embedded mode.
