Programming nRf51822 for central/peripheral role?

nar0909

Hi, I am trying to flash program an nRF51822 module to operate as both central/peripheral role. So I'm looking for some advice on how this could be done?

Programming Hardware: Black magic probe (BMP), which is a JTAG and SWD Adapter used for programming and debugging ARM Cortex MCUs.

Nordic Device: nRF51822 QFAA G1

Interface: arm-gcc cmd line tool, Eclipse(neon with GNU plugin) (Is this ideal? , I have come across developers using Keil uvision?)

So the idea is to program two modules to be operating as both in central and peripheral roles with UART service, while being able to use the Nordic toolbox app to send a command to tell the BLE device to operate as a central or operate as a peripheral.

Please let me know how this could be performed?

How do I use the compile ble_uart_s130 from SDK 10 and flash it into my target device through SWD/JTAG? Is there an example eclipse project I can use?

I have gone through this page but it uses a Segger J-Link.

Thanks

    Hi,

    Maybe this blog post could provide you with some useful information? Unfortunately, we do not have any tutorials or guides for other programmers than the supported Segger J-Link tools. All our software is built for use with J-Link, so I would recommend you to get a J-Link to take advantage of all our tools. Our nRF51/nRF52-DKs come with on-board J-Link debugger that can be used for programming external boards as well.

    The s130 softdevice can operate in both central and peripheral role, concurrently. I would recommend that you start with ble_app_uart example, and extend your application from this. If you are starting a new project with nRF51, please use SDK 12.3 instead of SDK 10. For nRF52 series, use the latest SDK v14.2.

    Best regards,

    Jørgen

    Most examples in the SDK comes with precompiled HEX-files, that you can use for testing. To compile the examples yourself, you need to use one of the supported compilers, Keil, IAR, or GCC (and Segger Embedded studio in SDK 14). If you do not want to buy an expensive license, GCC is the only free alternative without any size restictions. The Eclipse + GCC tutorial should described the required tools. If you want to use an IDE, Eclipse will also generate HEX-files (it use GCC for compilation). This can be flashed to the board as described in the above linked blog post.
