WP Series Sleep question

Hello folks.

I got a project here, where I need to send a notification to tower after 2 minutes after power outtage. The device must last 15 years, so I don’t want to use lithium Ion battery, or at least will try not to.
I would like to use super caps. Is there a way to put this modem to sleep for 2 minutes without disconnecting from tower?


Hi vladlozo1,

Not sure about the battery/supercap design, believe you want WP to operate in low power consumption during 2mins and keep network registration?

If that’s the case, you can refer to USB-SS mode in PTS for details.


Hi @vladlozo1

Which module you use?
Most model of WP76xx have ULPM mode.
You could use a timer(few second to few day) to wake-up module.
In ULPM, module will entry deep sleeping and no any network connection.
However current consumption able down to <50uA(depending model).

You could also consider PSM mode(supported ALL WP76xx), if you need more function support. However the current consumption will higher than ULPM mode.
