Moving from CC2541 SensorTag to CC2650 SensorTag

Other Parts Discussed in Thread: CC2650, CC2650STK, CC2541, CC2640

I have a couple questions regarding the new SensorTags:

1. On the CC2650STK webpage, it states "The new SensorTag is based on the CC2650 wireless MCU, offering 75% lower power consumption than previous Bluetooth Smart products." Is this in comparison to the CC2451 SensorTag? If so, how was this power consumption measured?

2. Is the firmware from the CC2541 SensorTag easily ported to the new CC2650 SensorTag platform? What would need to be adjusted to make sure that prior software designs can be supported on this new SensorTag?

    Hi Kyle,

    For 1, the CC2650 platform does offer significant power savings as compared to the CC254x. However, the actual savings will be based on the use case. Please refer to the app note for measuring power on the CC2640: www.ti.com/.../swra478

    For 2, The CC2650 SensorTag uses different sensors and takes advantage of the RTOS. I suggest taking a look at the CC2640 SW Developer's Guide and comparing the CC2541 & CC2650 projects.

    Note that CC2650 & CC2640 are interchangeable in this context since both devices are running BLE.

    Best wishes
