    Murata 1DX + STM32F412 based on Murata 1LD



      I ordered the Murata 1LD but due to long lead time I decided to order Murata 1DX ( using Avnet eval board: AES-PMOD-MUR-1DX-G ) and STM32F412 (using ST eval board: STM32f412Discovery).

      I added Murata 1LD files to my Wiced 6.2.1 files add support for ST-LINK V2.1 (based on article in the blog) and I programmed succesful the STM32F412 but It is don't work.

      Make taget command: snip.bluetooth.serial_gatt_service-MurataType1LD download run


      I will add few details about the connections:


      My connections:

      PC2 to BT_REG_ON

      PC0 to BT_HOST_WAKE

      PC3 to BT_DEV_WAKE


      /* Bluetooth control pins. Used by libraries/bluetooth/internal/bus/UART/bt_bus.c */

      static const platform_gpio_t internal_bt_control_pins[] =


          /* Reset pin unavailable */

          [WICED_BT_PIN_POWER      ] = { GPIOC,  2 },

          [WICED_BT_PIN_HOST_WAKE  ] = { GPIOC,  0 },

          [WICED_BT_PIN_DEVICE_WAKE] = { GPIOC,  3 },



      UART Connections:

      PA2 (TX) to BT_RXD_IN

      PA3 (RX) to BT_TXD_OUT

      PA0 (CTS) to BT_RTS_OUT

      PA1 (RTS) to  BT_CTS_IN


      /* Bluetooth UART pins. Used by libraries/bluetooth/internal/bus/UART/bt_bus.c */

      static const platform_gpio_t internal_bt_uart_pins[] =


          [WICED_BT_PIN_UART_TX ] = { GPIOA,  2 },

          [WICED_BT_PIN_UART_RX ] = { GPIOA,  3 },

          [WICED_BT_PIN_UART_CTS] = { GPIOA,  0 },

          [WICED_BT_PIN_UART_RTS] = { GPIOA,  1 },



      My questions:

      1. The connections are right?

      2. I debugged using the scope and saw STM32F412 transmits and BT_REG_ON is 3.3V , but there is not any response from 1DX, I think I missing something and don't know . After programming I don't find the device in BLE scanner on my phone

      3.  I am able to program but not debug .. I tried to use snip.bluetooth.serial_gatt_service-MurataType1LD download debug but it didn't work
