Hi, I have already read BCM4343W with Bluetooth H5 protocol and BSA Sample Client Applications Source Code and BSA Server API Documentation topics.

We need to use H5 and with your 'bsa_server' it works. But our gatt-client app use bluez. I tried to adjust hciattach for this(enable 3-WIRE mode). It doesn't work yet.

Maybe we can use 'bsa_server' in production? If so, where I can find API docs? 

*Cypress/CYW4343W IC.(linux 4.1.15). Bluez - 5.52

It's very strange, but H5 work with btattach:

$ btattach -B /dev/ttymxc2 -P bcm -S 115200 -N

But without 'slip' protocol(like H4 without flow control)! I see packets with sniffer.

And only when cts and rts pin in the low state.
