Hi
1. In order to debug by HCI tester tool, Connect 4-wire UART according above picture. Tx, Rx, CTS and RTS.
Because CC2564C UART output is 1.8V, is it must add a level shift between CC2564C and hoster? Is there any more pin need to be connected?
2. There is no level shift on hand, so we try to connect it by 3-wire UART, Tx, Rx and GND.
I can see the signal send out from Host, but no response from CC2564C, Is there any connection error? Thanks.
