    CYBT-343026-01 receive API command but no response sometimes

    YaTr_3516311

      Hi,

       

      I use CYBT-343026-01 module with ezserial_343026-CYBT_343026_EVAL-rom-ram-Wiced-release FW. I tested it via uart send API command to it. But find two problems.

      1. Command's response is not always back.

      For example, I send many times of "/QFV\r\n", but the reponse is not back 100%. And I check the uart data via oscilloscope of the BT module RX, recieve completely OK, but module TX no data. I don't know why? Need I set ".CYSPPSP,E=0"? Or do something for CYSPP pin?Below is the screenshot for RX data.

      2. If I send "/QFV" and "GAD" many times, commans no response(as 1 descriped). Then "GAD" been sent again, but "/QFV" response come back. It is strange.

       

      BR,
