Hello Nemorap,
We recommend that you use stand by mode to keep from having to reprogram the modules every time you it is turned on. Setion 9.6.tells you how to set it up:
Standby mode is a power saving mode that shuts down the RF section of the
module and puts the processor into a standby mode. The RTC is kept alive,
and the RAM power is maintained to keep the module configuration.
The standby state can be initiated either with a hardware signal to Pin26 or by
using a command.
Hardware controlled Standby: Enable standby mode by a low state to Pin26
(HW_S). To wake the module back to full power a high state needs to be
applied to Pin26. If Pin26 is not to be used, then it must be kept floating (not
connected).
Standby mode command: Software on the host needs to send the “PMTK161"
command through the UART interface.
To enter backup mode the VCC simply needs to be removed. Once initiated
the RTC and all configuration is saved along with any ephemeris data to allow
quick TTFF once the VCC is re-applied. BV needs to be applied at all times for
backup mode to run correctly. You may also need to set up back up mode as well.
