Question about the bootloader

[Ukoolele]

Hi,

I am working on a project and I want to program the nrf52832 with the arduino IDE with this package (https://github.com/sandeepmistry/arduino-nRF5). I want to use Arduino because I learn to use BLE with the Sparkfun nrf52832 Breakout Board (https://www.sparkfun.com/products/13990).

So I want to put an arduino-compatible bootloader into the nrf52832 chip, but I don't know how I can do that, I don't know how that works could you help me ?

Have a good day !

What's an Arduino-compatible bootloader?

[Ukoolele]

Hum I don't really know, ahah, but in the Sparkfun board, they put their hown bootloader, and with this bootloader I can make my program as an arduino board. I found this bootloader here : https://github.com/sparkfun/nRF52832_Breakout/tree/master/Firmware/bootloader-custom, but I don't know how I can put it in the nrf52832. Could you help me ?

According to the readme, that's just the UART bootloader from SDK 11 slightly modified to enter bootloader using specific pins. There's absolutely no mention about Arduino whatsoever.

If I were you, I would drop all that Arduino bloatware and work directly with Nordic's SDK.

If you use third-party libraries you will have to rely on the third-parties for support. The Arduino "core" has about one commit/month, and the bootloader you posted was last updated over two years ago. From my perspective, your support needs won't be met.

If you use standard Nordic resources, you can get all the help you need straight from this community and Nordic's technical support.

I see no reason why you should go use Arduino's IDE to develop anything.

I choosed to use Arduino because this is simpler than the Nordic SDK ! Before the Sparkfun's Breakout Board, I bought the nRF52DK and I didn't understand nothing about this card. I have a good level in programmation (I worked on PIC16F for example). To change the chip select pins with the GPIOs for each SPI slaves, with Arduino that tooks only 3 lines, with Nordic SDK, I searched during one week to do the same thing and that not works.

This is why I choosed that, I wanted to use BLE and Nordic Chip's are the best for that.
