SensorTile read the characteristic quaternions

Hello

My company bought the STEVAL-STLKT01V1.

I have to get the values of the quaternion's characteristic but it seems to be blocked.

In fact with my computer i can :

_ Connect in BLE to the sensorTile

_ Get all service's UUID

_ Get all characteristic's UUID

_ Get a few characteristics values like the Gas Gauge value (voltage, current, state of charge ...)

But when i try to read the value of the quaternion's characteristic i have an error.

It's like the value is accessible only with the STBlue MS app.

Please can somebody help me?

Thanks.

There isn't any limitation in accessing the characteristics from a different app.

Maybe the point is that the quaternion characteristic (0x00000100-0001-11e1-ac36-0002a5d5c51b) is “notification only� so it cannot be read, you just need to enable it ant you'll get the notifications.
