STEVAL-STWINKT1 with ST MEMS Studio is not working

[mdalal]

I am having STEVAL-STWINKT1 to be interfaced on USB channel for ST MEMS PC application.

I have flashed DATALOG2_Release.bin in eval kit.

I can get the ST MEMS PC Application showing the vibration sensor analysis graph. See attached.

However, the issue I am facing is when the ST Eval board is moved from the desk to up in the air (only 1 cm). The firmware is hung, and the USB connection is lost. Can you suggest what is wrong with the firwmare?

Also, if possible, I would like to connect the kit BLE channel with the ST MEMS application but it does not connect even then on MEMS applicaiton. Can you suggest if I need to use a different firmware? Or something else?

Hello,

I’m unable to replicate the issue. I can stream the data without any interruptions using the same setup as you. Based on your symptoms, I would suggest checking your USB cable and the USB connector on the board. There might be a weak connection causing disconnections when the board is moved.

Please note the following:

• MEMS Studio does not support Bluetooth connections with the Datalog2 firmware.
• The Datalog2 firmware can be used with the ST BLE Sensor mobile application.
• Alternatively, you can create firmware in AlgoBuilder within MEMS Studio by selecting the target STWIN BLE. This firmware will communicate with MEMS Studio over BLE, allowing you to stream sensor data to the application.

THanks for the reply.

I tried with 5 different USB cables and all have same issue. The Green LED which gets turn ON and Off is also stuck which geenrally suggests something is wrong with the firwmarew itself.

Can you provide me a link to the firwmare you are using? Or you can attach the firmware here itself.
