UART current consumption

[Michael01101]

Hello,

I developed an application for a custom nrf52832 board. It uses the Nordic UART Service (NUS) to transmit data over BLE. This works fine.

At the moment I am trying to optimize the current consumtion of this application on the custom nrf52832 board. I have already made some measurements and I figured out the following:

If I initialize the UART by calling the uart_init() function, my current consumption increases by 1,35mA (V_cc = 1.8V). This looks a bit too high for me.

Can you please answer my following questions:

1. Is this the normal current consumption of the UART?

2. Are there any ways to lower the current consumption of the UART?

Thank you very much in advance.

Hello, 

thank you very much for your support. I will take a look to this.

Hello Jorgen,

Is there an equivalent in NCS 2.0.2? We are running into similar power issues, but unsure how the nrf5 sdk changes in this thread translate to NCS.

Can you please post your question in a new ticket, explaining exactly what you are looking for? NCS are quite different from nRF5 SDK.
