GUI software description

The BlueNRG-MS GUI included in the software package is a graphical user interface that

can be used to interact and evaluate the capabilities of the BlueNRG-MS network

processor.

This utility can send standard and vendor-specific HCI commands to the controller and

receive events from it. It lets the user configure each field of the HCI command packets to

be sent and analyzes all received packets. In this way BlueNRG-MS can be easily managed

at low level.

3.1

Requirements

In order to use the BlueNRG-MS GUI, make sure you have correctly set up your hardware

and software (BlueNRG-MS GUI installed). The STM32L in the STEVAL-IDB005V1 kit has

been preprogrammed with a demo application (see Section 5). Hence, new firmware must

be loaded into the STM32L. Firmware images can be found within the firmware folder. The

firmware image that must be programmed is latest BlueNRG_VCOM_x_x.hex available

within the BlueNRG DK SW package. The GUI has the ability to Flash new firmware.

In order to download binary images into the internal Flash of the STM32L, the

microcontroller must be put into a special DFU (device firmware upgrade) mode. To enter

DFU mode:

BlueNRG-MS development platform (STEVAL-IDB005V1)

–

Power up the board

–

Press and hold USER button

–

Reset the board using RESET button (keep USER button pressed while resetting)

The orange LED DL2 will start to blink

–

Release USER button

–

Use BlueNRG-MS GUI to Flash the device with new firmware (Tools -> Flash

motherboard FW).
