## What is ST BLE Sensor?

The ST BLE Sensor application is used in conjunction with an ST development board and firmware compatible with the BlueST protocol to give you access to all the sensor data, which you can log to different cloud providers, and to update the board firmware directly from a mobile device via the Bluetooth® Low Energy protocol.

After discovery ST development board, the app shows you a list of available demos and you can navigate through them to discover the functionalities of your board. Demos can be related about environmental, cloud, audio, board configuration, machine learning and and many other functionalities.

The application is built on top of the BlueST SDK library implementing the BlueST protocol and helps you export the data easily via Bluetooth® Low Energy.

The application also supports firmware library algorithms like motion-sensor data fusion, activity recognition and pedometer functionality.

Both SDK and application source code are freely available at: https://github.com/STMicroelectronics

## Key features

- Access sensor data
- Log data to cloud

### 2/5 — Bluevoice Audio Stream Recording and DFU capability gone!!

*2022-12-22*

In the latest version (4.17.3) the menu that gives the option to record bluevoice audio streaming and perform ota update has gone. Please fix this to get better review.

### 1/5 — Basics do not load

*2022-11-04, version 4.16.1*

To start it says update the firmware so I clicked yes. This was to v349. Had to attempt that 5 times, bricked it, brought it back to life by loading boot. After a few more attempts it updated to v349 successfully.

Following the YouTube videos etc nothing works as described. Example; create app pedometer; press play screen flashes something so fast you can’t read it. Go to connect and all it shows is the original icons and says not available under them.

### 1/5 — Crashes when you press “connect”

*2022-03-03, version 4.14.5*

App is now unusable as it crashes when you press the connect button on the first screen.  It’s before you ask it to even connect to a device.

### 1/5 — Unusable with 4.14.5

*2022-03-03, version 4.14.5*

This app was decent, and worked until this update. Now it crashes when I hit "Connect to a Device". The app can see the devices and can upload firmware, so this might be a permissions issue with this version?

### 2/5 — Defficient

*2022-02-06, version 4.14.1*

The generic MQTT connection doesn’t work with iOS, appears a message that says:
KCFErrorDomainCFNetwork error 1

### 2/5 — No BlueNRG-LP support now?

*2021-12-23, version 4.14.0*

I used to use this go to OTA on the bluenrg-lp but now the latest version doesn’t offer me this product type. What’s going on? Is there a new tool or am I now just not able to do OTA?

### 2/5 — Screen size drastically restricted in new update.

*2021-04-22, version 4.8.0*

This app used to be great, but with a recent update, now only takes up about 2/3rds the screen on an iPhone XR, making the app much harder to use. There are large black bars on the top and bottom of the screen. Please fix this, ST!

### 3/5 — Not complete

*2020-11-20, version 4.6.4*

It has its flaws, I cant see the whole app screen on my phone it is cropped

This update introduces two new demos: Asset Tracking Demo and MQTT Demo. Additionally, it includes bug fixes to enhance overall performance and stability.


The Asset Tracking Demo is available for the STEVAL-MKBOXPRO (SensorTile.box PRO) board with the STBP-ASSET-TRACKING v1.0.0 firmware and the following adapter boards:
• STEVAL-MKI247A → An adapter board (for a standard DIL24 socket) designed to facilitate the evaluation of the LSM6DSV80X 6-axis IMU. Learn more at: https://www.st.com/en/evaluation-tools/steval-mki247a.html
• STEVAL-MKI251A → An adapter board (for a standard DIL24 socket) designed to facilitate the evaluation of the LSM6DSV320X 6-axis IMU. Learn more at: 
https://www.st.com/en/evaluation-tools/steval-mki251a.html
