Which FW stack version for BlueNRG-M0 and BlueNRG-X Radio Init Wizard

[MD'Si.1]

Hello,

I am trying to build my Bluetooth application by configuring the services and characteristics I need. I saw ST recommends using BlueNRG-X Radio Initialization Parameters Wizard.

I am using BlueNRG-M0 (X-Nucleo-IDB05A2) and I read the FW version and HW version from the board.

HW Version - 49(dec)

FW Version - 1840(dec), 0x730 (FW 7.30)

I want to know what FW stack version do I use in the Radio Init Wizard program (see attached picture). I assume the BlueNRG-M0 is a BlueNRG-1 device. Is that correct?

Eventually I am looking to support 8 GATT custom services on the device. I think the device can support up to 8 services as I read that in the release notes from ST (can't remember where).

Thanks,

Hi @MD'Si.1​ ,

BlueNRG-X Radio Init Wizard intend to be used with BluuNRG-x SoC ONLY.

BlueNRG-M0 module is based on BleuNRG-MS which is a BLE network processor.

With BlueNRg-M0, you need HOST microcontroller (typically STM32) to run your BLE application.

About SW, I recommend to use "X-CUBE-BLE1" SW package available on st.com (this package is compatible with CubeMx).

Regards,

Sebastien.

Thanks @Sebastien DENOUAL​ I have found the BlueNRG GUI tool so I think this will help me achieve the same goal as the Radio Init Wizard.

I have one question on the limitations of the different stack modes when reading the documentation.

 

What is the limiting factor when creating services or characteristics? e.g. the stack supports 700bytes - (36) - (device name length) for characteristic records. Does that mean that the length of all my characteristics needs to be ~660 bytes?
