TX power: -40 dBm
Advert
29 byte payload
20 ms interval
Average BLE advert current burst
(excluding advertising Interval): 1.960 mA
Refer to table for worked out total BLE
advert average current for given
advertising interval.
Aside:
Peak TX current: 3.6 mA
Peak RX current: 6.01 mA
Table 13 and Table 14 has the measured "Average Connection (Burst) current" (for a given TX power) which can
be used to calculate the Total average current for any connection interval.
Table 13: Measured Total average current consumption profile (with DCDC ON) during connection in slave mode versus TX POWER for
minimum Connection interval of 7.5 mS. UART is OFF
