SW demonstration applications
In order to develop a software application for the STEVAL-IDB003V1 platform, it is
recommend to start with the reference demonstration applications provided within the
BlueNRG DK software package, in the Projects folder (
Figure 2
). The IAR Embedded
Workbench for ARM (EWARM) tool V6.60 is needed to build software applications running
on the STM32L microcontroller.
Pre-built STM32L microcontroller binary images for the reference demonstrations are
already available in the BlueNRG DK software package, in the Firmware folder (
Figure 2
).
To download an STM32L binary image, apply the following DFU procedure:
•
Open the BlueNRG GUI
•
Press and hold the STEVAL-IDB003V1 platform SW1 button
•
Plug the STEVAL-IDB003V1 board into a PC USB port
–
The orange LED D3 will start to blink: STM32L device is in DFU mode, allowing it
to upgrade its Flash image through USB interface.
•
From the BlueNRG GUI, select Tools, Flash Motherboard FW and follow the indications
to select the new binary application image to be downloaded into the STM32L Flash.
•
Wait for the DFU download process to complete.

Note:
For a description of the available BlueNRG demonstration applications and supported
platforms, refer to
Table 1
(UM1686 user manual).
The BlueNRG_COM_x.x.hex binary is also provided within the BlueNRG DK software
package, in the Firmware folder (
Figure 2: BlueNRG DK SW package structure and
content
). The user can reload it through the previously described DFU procedure.
