CC2650STK: Firmware issue

Part Number: CC2650STK
Other Parts Discussed in Thread: CC2650

Hello all,

A customer ask,

"I am working with cc2650 Sensor Tag and I am not able to find a firmware project in CCS cloud. The Sensor Tag project available in the (ble_sdk_2_02_01_18) doesn't work when I import it to CCS workspace. I manage to build and download all three projects (bim_extflas, SensorTag stack and SensorTag app) and I get a success at the end, but the firmware doesn't work nonetheless.

Will you upload a new firmware project to the cloud? Could you please tell me how to increase the sampling rate? When a firmware project was available in CCS cloud I changed the minimum update period in st-util.h to 10 ms and flashed the firmware on the SensorTag but the values fluctuated remarkably. I also want to change the accelerometer range to 16 g but this also doesn't seem to be possible since the accelerometer rage is apparently fixed to 8 g. "

Could anyone help me with this?

thank you in advance.

    Hello,

    I'm not sure what the build problem is since no build logs were provided. I suggest following the CCS project import & build procedure that is documented in the BLE SW Developer's Guide, SWRU393. The SensorTag firmware build procedure is located in the SensorTag User's Guide on the BLE Wiki.

    TI does not provide examples for changing the default MPU9250 configuration beyond what is provided in the SensorTag sample application. See the description of the movement service in the online User's Guide for a description of related files.

    Best wishes

    Hello ,

    Thank you for the answer.

    It is mentioned to refer the source code and datasheet for custom modifications but customer is not able to make the changes. Thus,could you please tell me how to change the sampling frequency from 10Hz to 100Hz.

    Thank you.
