Flash NRF52 by UART

[Flavien]

Hi everyone,

I would like to create my board like this one :

www.adafruit.com/.../3406

learn.adafruit.com/.../39913

I know that Adafruit changed the bootloader in them NRF52, so I would like to know if I can flash my nrf52 by UART without change the bootloader ??

Thx for reading,

Best regard,

Flavien

@Flavien, the nRF5x cannot be programmed via UART but you can use the IDAP-Link with Arduino IDE to program nRF chip. I have tested it myself sometimes ago. I may able to help to set it up.

If you load the uart bootloader then yes you can program it via uart but how are you going to program the uart bootloader into the chip ?
