Sleep mode GPRS/GPS Tracker HAT

End-of-Life Product GPRS/GPS Tracker HAT
#1

In the description of GPRS/GPS Tracker HAT it’s stated “Power-sensitive projects require advanced power controls and sleep mode features which become a great advantage of this board”
I am not able to find any documentation in this topic. Has anybody used sleep mode, or can i find documentation somwhere?

Thank you ensar. Is the DTR pin connected to one of the IO interface pins?

#4

No, it is not connected.
Instead, you can use the PWRKEY button.

#5

Ok, if the DTR pin is not connected i cannot understand how to put it to sleep mode. The PWRKEY will shut down the regulators. If I do that i have problems with the ppp connection when turning it on.

You can enable the sleep mode by “AT+QSCLK=1”.

You can enable the auto connect/reconnect service to avoid connection problems.
