We came to know that Packets has to be added before and a= fter the HCI commands according to H4 and H5 UART. Is it right ?.=20 We wish to know that whether it takes major development cycle. As per Silicon wave datasheet the 3 WIRE UART is compatible with BCSP. May we have to follow the H4 UART or BCSP one for our development. Advise us.
