    Bluetool software with non FTDI UART bridge

    MiSh_300256

      I had use Cypress USB Serial CY7C65213 demo board as com port in bluetool software.

      But it can not successful to get reset command complete log, but logic analysis UART log can show the rest command has complete.

      Does Cypress/Broadcom bluetool software only support FTDI UART bridge?

      Thanks,

      Mitchell

          The bluetool software can support CY7C65213, all the module demo kit use the CY7C65213 as the USB to UART tool and works fine.

          Please check if you have enabled the RTS/CTS, the HCI UART need the flow control to works well.

            Follow application note the CTS flow control can not select.

            I had tired CTS flow control select to enable, even FTDI also fail to get successful massage as below.

            13:03.236  com197 --  Protocol set to HCI @ 115200

                       com197@115200

                       com197@115200

                [03 0C 00]

                opcode = 0xC03 (3075, "Reset")

             

            When CTS flow control uncheck, the reset command is success.

                [03 0C 00]

                opcode = 0xC03 (3075, "Reset")

             

             

            14:05.836  com197 <c  Reset

                [0E 04]: 01 03 0C 00

                event = 0xE (14, "Command Complete")

                Num_HCI_Command_Packets = 0x1 (1)

                Command_Opcode = 0xC03 (3075, "Reset")

                Status = 0x0 (0, "Success")

             

            So I can't enable CTS/RTS to get successful result.

              Which device are you using? CYW20732 or other? Can you send HCI Reset Command successfully with other UART software tools?

                I tried on CYW20704  CYW20706 CYW20719.

                And just use CyBluetool & Broadcom BlueTool software to send reset command.

                Both software can successful to send out HCI Reset Command with FTDI UART bridge.(non flow control)

                Then use logic analyzer can trace Cypress bridge reset command successful, but not show success RX logs on bluetool.

                  I find some power sequence issue to get this problem.

                  Now CYW207xx system board power is equal or early provided, the CY7C65213 reset command can successful.

                  If UART power is early then system board powered, bluetool software will have problem to get error massage or reset command not successful.

                  Even power sequence is correct, bluetool software need close then re-run again to get successful result.
