X-NUCLEO-WB05KN1: Which Firmware and App to Toggle LED via BLE?

Hello,

I’m working with the X-NUCLEO-WB05KN1 shield and a STM32 Nucleo board.

My goal is to make a simple demo: Toggle an LED on the board by sending a command from my smartphone. Display something on the smartphone when pressing the User button on the Nucleo.

I understand that I need to update the shield with the BLE_Transparent_Mode_STM32WB05_location_essential firmware from X-CUBE-WB05N_V2.0.0.

However: Which exact firmware binary should I flash for this purpose?

Which smartphone application should I use to communicate with the board?

Is nRF Connect sufficient or is there a recommended alternative?

 

Thanks in advance for your help!

 It could certainly do it, but it's a competitor's app - so this is not the place for support with that!

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

Hello,

Thank you for your reply.

The smartphone application is not mandatory for me, I’ll just use my phone as a tool.
I mainly need to know which application or tool you recommend to interact with the WB05KN1.
Could you please advise?

Thanks again!

Yes, the nRF one is perfectly fine.

The beauty of standards like BLE is that they are totally agnostic to the hardware: so all the app sees is BLE Characteristics, Services, Advertising, etc - it neither knows nor cares anything about what chips your device uses.

The point is just that it's a competitor's tool - so you won't find any support for it here.

In that case, could you suggest a non-competitor application that I can use, so I can also get support here if needed?
I’d rather use a tool aligned with your recommendations, if that’s not an issue.

Thanks again!
