1. What would be the best way to wake-up the Lora module from sleep mode? I have understood it is not possible to wake up directly to I2C signal because connection is dead in sleep mode. But instead I have to use some connection pin to wake up the board. Which pins I should use? Are there other options, what would you recommend?
2. What is the recommended Arduino library which I could use to setup the sleep mode or do you have some example code?
