    Upgrade FW without ble connection and with MCU via puart



      I have a MCU to connect Cybt-343026-01 via puart. I want to upgrade bt modul’s FW. For example, puart receive a defined command, then transmit the needed fw data via puart. Is it Ok? I know I can use HCI uart command, but now I just connect mcu to bt via puart. and I see “wicked-hci-protocol” and “hci-uar-spi-bridge“ exampl, need SPI? I’m confuse.just connect mcu to bt via puart ok or no? or need other hardware pin needed?
