High Power Consumption on STM32WL55 Dual-Core End Node Application

Hello everyone,

I'm currently working on a LoRaWAN End Node dual-core application using the NUCLEO-STM32WL55 board, and I'm facing unexpectedly high power consumption during transmission. I'm seeing very high current consumption — around 220 mA. I would like to reduce it, but I'm not sure what I'm missing.

Any help or advice would be appreciated. Thanks!

Hello @marouax 

Could you give more details about your configuration and how you are able to see such a consumption (how are you measuring this current).

Best Regards.
