Making a wireless keyboard

[safkans]

Hello, my dear forum friends.
Hoping for your support, I'd like to ask you for advice on something. I want to build a very low-current wireless keyboard. I can do this with a 2.4 GHz dongle or directly with a BLE. My top priority is current consumption, and my second priority is ease of use. I bought an nRF52DK for this project. However, despite programming with Nuvoton, STM, and Microchip, I haven't been able to figure out exactly what Nordic uses. I usually use Keil, but to save time, a quick search seems like it could also be done with the Arduino IDE. Has anyone tackled this before? Could you help me with some guidance?
