Power Consumption Problem in RAK3172

Hello guys,

I was using RAK3172 LOW LEVEL DEVELOPMENT Reference (SDK), but i have an issue about it, that ı cannot solve. When i use RAK3172 with AT-SLAVE MODE i can see 2 microAmpers but when i use My Custom firmware, i can only see 2 milliAmpers. What is the problem with it? Did anyone see the same issue?

Are you using STOP-Mode2 in your custom firmware?

In StandbyMode… i am working on. That is everything that i know about it. I think there is a issue about it.

Could it be that the Radio is always ON in your custom code?

I think that is my problem, so can you help me how can i solve it? Is it enough to active Stop2mode in order to make radio always ‘OFF’? Can you give me any sample code for it?

@carlrowan I have a similar problem.#define DEBUGGER_ON 0, #define LOW_POWER_DISABLE 0 .When I measure like this, I see 300-600uA. #define LOW_POWER_DISABLE 1 .When I do I see 2-3mA. in 1.0.0 software I only changed these.I can’t find how to lower 1.69uA. Can you help with this?

The 1.69uA on our specs is based on RAK firmware. If you are working on your own custom firmware, you have to look on the things that might be on or configured to consume more current like speed of GPIO, on peripherals, etc.
