IKS4A1 and Unicleo-GUI Issue

[WinstonZ]

Hi,

I have purchased a sensor expansion board (X-NUCLEO-IKS4A1) for my board (NUCLEO - F446ZE). However, when I wanted to display the data on Unicleo-GUI, the GUI cannot detect anything, not even my firmware. I looked through the datasheet for Unicleo-GUI and I did not see IKS4A1 being a supported model for the GUI. Could this be the issue?

In terms of setting up the board, I basically followed "Getting started with X-CUBE-MEMS1 with STM32CubeMX" document, specifically the steps under section 7.2 --"Use of MEMS Library with sample applications for X-NUCLEO-IKS01A3 or X-NUCLEO-IKS02A1 or X-NUCLEO-IKS4A1". Am I following the wrong step?

Best.

Hello @WinstonZ,

Check the serial settings to interface with Unicleo-GUI: baud rate 921600 bps; 8 data bits; No parity; 1 stop bit; no hard flow control (as mentioned in the UM1859 - page 5)
