CC2650 SensorTag Software User's Guide

This User's Guide provides gives details of CC2650 SensorTag BLE firmware including basic operation, sensor overview, GATT tables, conversion algorithms and overview of Bluetooth low energy commands used to communicate with the phone. SensorTag firmware is delivered as part of BLE Stack, available for download here.

Battery Notice

Warning! This kit includes a non-rechargeable lithium battery. To minimize risk of personal injury and/or property damage due to potential of explosion/rupture of battery, always make sure battery is completely removed from the CC1350STK/CC2650STK when connected to an external power source. External power source cannot exceed 3.6VDC. Dispose the battery properly and keep out of the reach of children at all times.

When replacing the battery use only UL-1642 approved CR2032 batteries. Please check the replacement battery temperature ratings and do not use the CC2650STK outside of the battery manufacturer specified temperature range. CR2032 Batteries from the following suppliers have been tested and approved for use with the SensorTag: Energizer, Varta, Sony, Panasonic
