To accurately measure the power consumption of the CC2640R2F, all jumpers on the CC2640R2 LaunchPad must be removed. The Measuring Bluetooth Low Energy Power Consumption application report shows an example of the LaunchPad with all the jumpers removed. With all the jumpers removed, the CC2640R2F was powered by connecting the VDD output of the power analyzer to one of the 3V3 pins on the LaunchPad and the GND to any of the GND pins. A 3.3-V DC output was used to power the CC2640R2F LaunchPad while measuring the power consumption.
When measuring power with the JTAG jumpers removed, programming and debug capabilities of the chip become unavailable.
