Stop and restart via LPTIM

[UmbertoL]

Good morning,

I am working with the MB1389E board and STM32CUBEIDE. I need to put it into low power mode for a few minutes and then measure and transmit data when it wakes up.
I tried the LPTIM_Timeout example (included in the STM32Cube MCU Package examples for STM32WL Series), which should make an LED flash at the end of the time set in the timer, but I can't get it to work. Does anyone have any suggestions, information or working code?

Thank you,
Umberto

Hello @UmbertoL and welcome to the ST Community.

If you want to work on a Wireless program that transmit a data and enter low power mode for a precise time before transmitting the next message. I suggest you use the timer server together with the low power implementation for the STM32WL stack. More details may be found on the chapter 9.2 and 9.3 of the AN5406.

Best Regards.
