Lorawan Interrupt taking more power STM32WLE55X and LPTIM is not working with Lorawan

[Geni]

Hi

I am  trying to interface the STM32WLE55x lora module to a pulse counter. when I tried with interrupt as a counter (as i have to count the pulses!!!) its taking 123mA current at the time of sending the data to server and on ideal condition it is taking around 5 to 6ma!!!! This seems very high for me. I am trying to develop this on a battery so it will kill my battery. 

I have tried using LPTIM with LORA wan but its not taking as interrupt for LPTIM even the LORA is getting connected or unconnected, the interrupt is not performing tasks what it suppose to.

any one have idea to reduce current in interrupt mode or how to enable LPTIM interrupt so it can perform the tasks.

Thanks

Hi,

We are also encountering same problem, as LPTIM is not working with HAL and LL library using LORAWAN and interrupt is taking more power for counting the number of high and low cycles. 

If anyone have the solution on it please send.

Hello @Geni @Omkar_123 

I suggest you use the system of timed task execution based on the Timer Server that you can create and configure on your LoRaWAN application.

More details can be found on the AN5406.
