.
10. Put the device in Sleep mode before measuring the current or the current consumption will be approximately 4
mA.
To put the device in Sleep mode, toggle position 1 and 2 of the SW4 (refer to
and
to set
BT_WAKE to high).
The results from the N6705A DC power analyzer are shown below. The average current consumption for the
advertising mode is 162 μA with 4 bytes of data. It is measured over 2.56 seconds (advertising interval).
The actual current consumption is approximately 142
μ
A. The front-end module (U2) needs to be
removed. There is 20
μ
A of leakage, which is difficult to remove
.
