Password operation result notification, convenient APP programming;
23. A low-power standby mode, the CC2540 chip sleep current official data 0.4uA, the measured power module is as follows:
* 1 Note: The official test mode: In the power loop resistor string 10R, use the oscilloscope to intercept the waveform drop,
Points calculation.
* 2 NOTE: Multimeter test mode: Use the multimeters uA or mA profile string view to display the values ??between the cell and the module.
The test voltage is 3.07V.
