Features

• Firmware image for use with upgradable BlueNRG-2N Bluetooth

Low Energy

network processor

• Provided in binary format only, as it is not intended to be modified

Description

The package contains a Bluetooth Low Energy stack firmware image supporting the

upgradable BlueNRG-2N Bluetooth

Low Energy network processor, which is a low

power Bluetooth Smart IC, compliant with the Bluetooth specification.

The image is provided in two formats:

*.c: suitable for device firmware reprogramming during volume manufacturing of

customer boards.

*.bin: suitable for device firmware programming on bench with the ST GUI for

prototype bring-up and also for device firmware reprogramming during volume

manufacturing of customer boards.

It supports SPI or UART interface selected through GPIO.

The device comes pre-programmed with a production-ready stack image; the version

of which may change at any time without notice. The software version of the

preloaded stack image can be retrieved through a specific API command (refer to the

SDK documentation for further details). New stack image firmware may be made

available by ST in the future and will be offered free-of-charge to end users through

ww.st.com. End users will be able to upgrade parts with the newly downloaded stack

image through the ST provided software tools and reference code. Firmware is

provided in compiled form since it is not intended for modification by users.
