I’m using Atmel Studio and ASF to program and test RAK4260. I started to use serial communications, external interrupts, timers, RTC and GPIOs with success. However, I tried to put the device on Backup mode and the current comsumption does not fall. Now, with all GPIOs in 0, the current is ~1.8mA @3.3V. I suppose that the module has more peripherals to deactivate, right?
