WARNING
It is recommended to set the ON_OFF/WAKE line HIGH to power on
the module only after VBATT is higher than 3.20V.
In case this condition it is not satisfied you could use the
HW_SHUTDOWN* line to recover it and then restart the power on
activity using the ON_OFF/WAKE line.
After HW_SHUTDOWN* is released you could again use the ON_OFF/WAKE line to
power on the module.
Auto Power On
ML865G1 module can be switched on with ON_OFF/WAKE pin 7 permanently fixed to HI
level (1.8V).
In the configuration there are two limitations:
• the asynchronous PSM wake-up cannot be implemented.
• Power Off can be only implemented via AT command (see ML865G1 Software User
Guide, AT#SHDN)
Power Off
Turning off of the device can be done in two ways:
• via AT command (see ML865G1 Software User Guide, AT#SHDN)
• pin ON_OFF/WAKE asserted (HIGH) for at least 3 seconds
Either ways, the device issues a detach request to network informing that the device will
not be reachable any more.
