hello,
I have the Arduino Portenta and LoraWan Shield and I'm trying to get the device to sleep, however it wont sleep in between sending a lora message. The script works fine without " LowPower.deepSleep(10000);" command. When the low power code is added i get the following when building. Any ideas how to get the portenta to sleep?
