BlueNRG IFR programming steps

Regarding IFR programming, two procedures are available:

•

The BlueNRG GUI IFR utility which is useful for bench testing and bringing up

application PCBs.

•

Dedicated external microcontroller firmware based on the BlueNRG IFR ACI utility

APIs, available within the latest available BlueNRG DK software package. This

example firmware can be used during customer PCB manufacturing.

Some reference IFR data configuration files (*.dat) are available with the BlueNRG DK

software package. These files can be used as a starting point to customize the IFR based

on customer needs.

BlueNRG GUI IFR programming

The BlueNRG IFR can be programmed by following the steps below:

•

Open the BlueNRG GUI available on the BlueNRG DK 1.7.0 or later software package

•

Connect the BlueNRG or BlueNRG-MS platform to a PC USB port

•

Load the prebuilt Virtual COM image BlueNRG_VCOM_1_x.hex available on the

Firmware\STM32L1_prebuilt_images using the GUI, tools, and Flash motherboard

firmware provided that the BlueNRG or BlueNRG-MS platform is in DFU mode (on the

Projects\Project\Virtual_COM_Port folder, an IAR project is also available for building

and downloading the Virtual COM image through JTAG).

•

On the BlueNRG GUI, select the associated COM port and click on the "Open" button

•

Select the Tools, BlueNRG IFR... utility and the View/Edit tab

•

Customize the IFR fields according to the user's needs or click on the “Load” button to

load a saved IFR configuration file (*.dat file).

•

Click on the "Write" button to write the IFR file into the BlueNRG or BlueNRG-MS

device IFR
