GUI software description

• Change HS startup time parameter. This parameter control the time offset between the

wakeup of the device and the start of RX/TX phase. It must be big enough to allow the

device to be ready to transmit or receive after wakeup from sleep. This time depends on

the startup time of the high speed crystal.

• Change sleep clock accuracy. This must reflect the actual clock accuracy, depending on

the low speed oscillator or crystal in use.

• Set low speed (LS) crystal period and frequency

• View/change date to distinguish between different versions of configurations.

• View registers that are written into the radio (hot and cold table)

• Set some test modes for specific tests

• Read IFR content from BlueNRG-MS.

• Write IFR configuration to BlueNRG-MS IFR.

The following general utilities are also available:

• Load button: allows to load a configuration file.

• Save button: allows to save the current parameters into a configuration file.

Flash motherboard firmware

The BlueNRG-MS GUI embeds a utility that allows to Flash firmware to the STM32L

microcontroller on the motherboard without a JTAG/SWD programmer. This utility uses a

bootloader that has been programmed in the first 12 KB of the Flash. Any application to be

programmed to the STM32L by this tool must first consider that the lower area of the Flash

is used by the bootloader(b).

OTA bootloader

OTA bootloader is a tool that allows to Flash new firmware to the STM32L of a remote

device via Bluetooth low energy technology. Refer to the dedicated application note for

more information.

Get production data

From the tools menu it is possible to retrieve production information from the BlueNRG-MS

daughterboard. This data is stored in the EEPROM on the daughterboard.

Get version

The Get version tool is used to retrieve the version of the BlueNRG-MS GUI firmware

(VCOM) on the STM23L, and hardware and firmware version from the BlueNRG-MS.

Settings

This tool allows to configure the firmware stack version to be used from the GUI (when no

device is actually connected to a PC USB port). Further, it allows to configure the GUI serial

baud rate (valid only for communication over serial UART and not through USB Virtual

COM).

In order to use this function.

Two precautions must be taken for any firmware: 1) change memory regions in linker script (vector table and

Flash must start at 0x08003000); 2) Change the vector table offset (NVIC_SetVectorTable())
