Delay when switching off PHS8 | Telit Cinterion IoT Developer Community

April 8, 2019 - 8:51am, 2507 views

Hi everyone,

In my application I have to save power and the PHS8 has only to run as long as the internet connection is needed. When switching off the module with AT^SMSO, it sends the OK answer immediately. Sometimes current drain disappears within one or two seconds but sometimes there is a delay of up to one minute until Vext and the current drain get low. When pulling the Emergency Off - line low during this delay,  Vext immedialy goes low.
Now I Have two questions:
What is the reason for that long delay?
Does it afflict damage to the module,  when I pull the Emergency Off - line low during this delay?

Can anyone help?

Thank you,
