  • Build and Debug the project

  • Check for the RESET pin:

    • If RESET pin is connected from STM32 to RS9116W EVK, then user need not press the RESET button on RS9116W EVK before free run.

    • If RESET pin is not connected from STM32 to RS9116W EVK, then user need to press the RESET button on RS9116W EVK before free run.

  • Free run the project

  • Then continue the common steps from Section 5.3

Refer EFx32 Getting Started, for settin-up EFR & EFM host platforms

  • Import the EFR32/EFM32 project from <SDK>/examples/_internal/Wireless_Examples/ble/ble_ae_central//projects

    • Select the appropriate .slsproj as per Radio Board type mentioned in Section 3.3 for EFR32 board. (or)

    • Select the *.brd2204a-gg11.slsproj for EFM32GG11 board.

  • Compile and flash the project in to Host MCU

  • Debug the project

  • Check for the RESET pin:

    • If RESET pin is connected from EFX32 to RS9116W EVK, then user need not press the RESET button on RS9116W EVK before free run

    • If RESET pin is not connected from EFX32 to RS9116W EVK, then user need to press the RESET button on RS9116W EVK before free run

  • Free run the project

  • Then continue the common steps from Section 5.3

5.3 Common Steps#

  1. Configure the remote BLE device in Central mode and scan for the DUT's address and give a connect.

  2. Observe that the connection is established between the desired device and RS9116W EVK.

  3. After successful program execution the prints in docklight looks as shown below.
