I am working on low level development on rak3172 breakout board. I am using Keil for development. main thing is getting data from gps and putting rak to sleep. Most of the work is completed, but I am facing this current issue.
The current of the module did not goes below 350uA. I have tried sleep mode. I have tried stop 2 mode with RTC (low power regulator on).
Stop 2: Stop mode with low power regulator and VDD12I interruptible digital core domain supply OFF (less peripherals activated than low power mode stop 1 to reduce power consumption)
Can you kindly guide me how can I achieve 2uA as claimed in datasheet.
