When the WISMO228 has had no activities for a certain period of time, it will enter
sleep mode automatically, regardless of the DTR level.
Any ASCII character on the UART can wake the WISMO228 up.
Refer to the WISMO218 AT Commands Manual for more information about the AT+PSSLEEP
command.
Power Consumption Values
Three VBATT values were used to measure the power consumption of the WISMO228: VBATTmin
(3.2V), VBATTmax (4.8V) and VBATTtyp (3.6V). Both the average current and the maximum current
peaks were also measured for all three VBATT values.
The following consumption values were obtained by performing measurements on WISMO228
samples at a temperature of 25° C with the assumption of a 50Ω RF output.
Note:
Power consumption performance is software related. The results listed below are based on the
software version TBD.
