CC2650STK: Barometric pressure readings

Part Number: CC2650STK


Hi all,

I just purchased 2 CC2650STK tags.  When they came in, they both had different firmware installed, I updated both to 1.32 (Oct 5 2016).  I updated using the TI OAD service because I have not purchased the SDK unit yet.

I am exploring the unit at this time and have not attempted to write any code yet to connect/pull data from the unit.  I installed the Simplelink SensorTag v3.0 (and v2.5) and am using that to view the following values.

My question is specific to the Barometric pressure sensor readings, both of the units (using the Android application) are receiving barometric pressure readings in the 460 range... currently it is reading 465.7.   These values don't make sense to me and I am trying to figure out how to interpret.  When I look at the pressure sensor built into my phone I'm getting numbers in the 800 to 900 range, which still are not quite right.  any help will be appreciated.

thanks,

-chris

    Hello Chris,

    As stated in the SensorTag User's Guide on the TI BLE wiki, the sensor readings are the raw, un-calibrated values read from the respective sensors. You will need to implement any calibration in your application.
