Using IKS4A1 with IDB05A2

[TonyKhoshaba]

 

I am trying to use IKS4A1 with IDB05A2 together with F446RE.
Each of these expansion boards works fine with F446RE. However, when I try to use STM32CubeMX to create a combined project, I cannot add the BLE1_applications. 

I assume this configuration should work so I can use MEMS data over a BLE1. Is my assumption correct?

If yes, then what is the best way to solve my issue in STM32CubeMX?

Hello @TonyKhoshaba ,

You can refer to the BLE application within X-CUBE-BLE1.

This application shows how to implement proprietary BLE profiles and runs on STM32 Nucleo boards with X-NUCLEO-IDB05A2 STM32 expansion board.

Running NUCLEO-IDB05A2 alone is not an issue. I can even see the simulated MEMS data in the iPhone app.

The problem is I cannot add IKS4A1 with IDB05A2 in the same CubeMX project and do not know the root cause? Is it the pin conflict and if yes what is the alternative configuration etc.

Why not - do you get an error message from CubeMX? In the software build? Something else??

You need to give full details:

On what basis do you assume that?

Have you checked the board pinout definitions and/or schematics?

Maybe they have pin conflicts ... ?

Note that when I run BLE1 with without adding MEMS1 board it works fine. 

When I try to add BLE1 and MEMS1 data logging application, CubeMX does not allow me to add IKS4A1. 

I do not know if this is just not possible, or it is because of pin conflict. I am very new to ST world so do not know the root cause yet. I was expecting stacking up ST expansion boards to be a bit easier and straight forward.

Currently considering using eval boards like STM32WBA which have integrated wireless feature (without expansion board) and maybe this will solve my issue.

But I rather root cause the issue of stacking the two expansion boards rather than changing the main eval board.

Hopefully ST can provide a suggested pin configuration that I can use.

Does it not give you any message or anything to say why?

You can check for pin conflicts by looking at the documentation for the boards. Also, look at the pin assignments that CubeMX uses when you use the boards separately.

It's just the same as stacking up Arduino shields - you have to check that the ones you're stacking don't have pin conflicts.
