5.1 Loading the RS9116W Firmware#
Refer Getting started with PC to load the firmware into RS9116W EVK. The firmware binary is located in <SDK>/firmware/
5.2 Building the Application on the Host Platform#
5.2.1 Using STM32#
Refer STM32 Getting Started
Open the project
<SDK>examples/_internal/Wireless_Examples/ble/ble_ae_central//projects/ble_ae_central-nucleo-f411re.uvprojxin Keil IDE.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
5.2.2 Using EFX32#
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//projectsSelect 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#
Configure the remote BLE device in Central mode and scan for the DUT's address and give a connect.
Observe that the connection is established between the desired device and RS9116W EVK.
After successful program execution the prints in docklight looks as shown below.
