https://devzone.nordicsemi.com/f/nordic-q-a/87554/nus-based-current-consumption-is-differentHello. I read this article https://devzone.nordicsemi.com/f/nordic-q-a/66914/uart-current-consumption I did my testing with ble_app_uart from SDK 17.0.2 on a nRF52832, and my power source is 2.5V. I think same condition but not same result. en-USTelligent Community 13Wed, 04 May 2022 11:11:08 GMThttps://devzone.nordicsemi.com/thread/366182?ContentTypeID=1Wed, 04 May 2022 11:11:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:471f0bea-fcb9-4b29-aaaa-e4ee5f44fbcfKenneth<p>Typically idle current consumption of the NUS example is about ~1mA due to it&#39;s in UART RX mode waiting for data, I notice in your case you have much lower current (~20uA), so that lead me to believe you have stopped RX here or have you also disabled UART? I would think you need to disable the UART in addtion if you want the lowest power (~2uA).
