How to upload bootloader and program hex file to NRF51822 on PCB?

[Sri_guy]

Hi,

I am attempting to make a PCB for NRF51822 and I was wondering how I would upload a bootloader to the chip? I can't seem to find it. The device in the end will be using the S130 softdevice. Also, say I were to compile code on the NRF51-dk with the NRF51422 on it, will the same code be applicable for the NRF51822. The code in question will be reading analog voltage from the analog input pins and will be transmitting voltage readings over BLE to a computer.

Thank you.

Hi

The difference between nRF51822 and nRF51422 is explained on this thread.

You can find precompiled bootloader on this path in nRF5 SDK 11.0.0:

\nRF5_SDK_11.0.0_89a8197\examples\dfu\ble_dfu_send_hex\test_images_update_nrf51\dfu_test_bootloader_b_s130.hex.

SDK 11.0.0 can be found on developer.nordicsemi.com/

The bootloader project is on this path:

\nRF5_SDK_11.0.0_89a8197\examples\dfu\bootloader\pca10028\

PCA10028 contains an nRF51422 chip.

Here is also a bootloader tutorial, just ignore the "packs" section because we do not support packs anymore.
