Unfortunately, we don't provide support on application development for Android or iOS. You can find the source code for nRF Toolbox for Android on our GitHub, this should help you on the way. Also, the tutorial you linked above creates an app exactly as you require.

The MDK is not the actuall IDE that you develop applications in. It just adds support for Nordic devices into the IDE. You need to download Keil from ARMs webside, and also download and install the latest nRF Device Family pack.

So now I understand better what's going on here. Thx. Since I already have the code for the ATmega chip. I would need to learn how to write my own java code in Android Studio for my Android phone. To connect to the nrF51..Nordic chip. That code would connect to the Nordic chip first, it would have 2 buttons, one sends the char (o) and the other one would send the char (c) for instance. The chip would then just pass those send characters on to the ATmega chip via spi, right? Can you guys help me writing the java code to connect to the Nordic chip? I have some Android developer samples put into Android Studio, but none of any of the codes will connect or even find the BLE device. The only code finding and connecting to the BLE device is the app from Nordic the nRFConnect which I found in the google play store. That's the only one working. Is there a special trick to it or what? So if you guys would help me to write a very small app to connect to the Nordic chip, then I would need to learn how to write the code for the 2 buttons, that's it. I'd be in business. Can I get support for that? If you think that I should rather buy another Nordic chip like the Dongle or so, I could do that too. But I still would need support in writing the code with you guys sdk and IDE. So I need support no matter what. So its your call now with what you want to support me with. Please let me know. Oh, I just today downloaded the SDK nRF5_SDK_12.2.0_f012efa, unzipped it. Inside it has all kinds of stuff and the MDK's nRF5x_MDK_8_11_1_Keil4 and nRF5x_MDK_8_11_1_IAR. I also installed JLink_V512g all 5 of them tools. However, the MDK will not install. It claims that it's finished installing but I can't find it anywhere. Isn't the MDK the actual IDE for the chip to write the program for it? Can't get it to install on my win10 home edition. Any idea how to help me? Thanks, Nick

Let me try to explain this once more.

The board you have (Adafruit Feather 32u4 Bluefruit) is an Arduino compatible board with two ICs, a ATmega32u4 (AVR) and the Nordic nRF51822. I guess the first is what you call "microcontroller", but actually both devices are microcontrollers. The nRF51822 is a system-on-chip, a microcontroller with a built-in radio, making it capable of doing wireless communciation. Here is a picture trying to explain your board:

The reason you cannot put the code you posted above on any nRF51/52 devices, is that it is written for the Arduino compatible ATmega chip, to operate the custom firmware in the nRF51822 chip.

To program any nRF51 or nRF52 chips, you should use the Nordic SDK and one of the supported IDEs (Keil, GCC or IAR). mBed is also supported, and this is more Arduino-like, but you will not have the same flexibility that you have with our SDK. You will also get better support when using our SDK.

To program the board, you need a programmer/debugger that support the SWD interface. Our development kits (nRF51 DK and nRF52 DK) and the nRF51 dongle have an on-board debugger integrated on the board, allowing you to program the chip directly by connecting the board to your PC via USB.

The link you provide only show Android code, this has nothing to do with the nRF devices. On the same page, you can however find a few articles about how to create applications using our SDK and the nRF51 dongle.

Best regards,

Jørgen

Thanks for the answers. However, I'm absolutely confused by now. You guys tell me that on a Nordic Chip I can't use this above code. Can only use it for an AVR board. I take it that by an AVR board you actually mean a microcontroller such as Arduino, right? So if I understand this correctly, I have to use Nordic's skd's like these: supported IDEs (Keil, GCC or IAR) which are different from the Arduino IDE and again are different from the mbed IDE as well, correct? So there is a BLE chip which can be programmed but uses its own skd and IDE, correct? And there is a board with a BLE chip and a microcontroller on it, right? Where on such a board I always program the microcontroller and not the BLE chip, correct? To program the Nordic chip such as this one: nRF52832 I would need such an IDE: (Keil, GCC or IAR), right? And to program the nRF51 Dongle: I can use an Arduino IDE, right? Which is an mbed IDE, correct? Sorry, but this is all very confusing to me! I just trying to straighten this out to find out what do I need to program the Dongle? Seems like that the Dongle is easier to program over the Nordic nRF52832. How do I even program the Nordic nRF52832? There is no way to connect it to a PC? But then I could just go ahead and keep the current chip Feather 32U4 I have. It has a microcontroller on the board, and a Nordic BLE chip. I could just wipe the micro controller chip, and the BLE chip just passes the characters from my Anddroid phone on to the micro chip, right. The micro chip is actually the one which does use the program I write, right? I can write code like the one above. Can use the code above also for the Dongle then? It uses: ARM mbed tool-chain. Would that be the code above? here is a link: link text to the guy who uses the nrf51dongle. Can you have a look and tell me what kind of coding that is? Is it the same code from above? Thanks, Nick

@Nick

Like @Jørgen says, this code is not designed to run directly on a nRF5x board. Its designed to run on a separate AVR based Arduino board, like an Arduino Uno, connected to a Nordic nRF8001 device.

You can compile and run Arduino code on the nRF5x devices.

RedBearLab have an old mbed based Arduino "Core" and more recently Sandeep Mistry has written a core from scratch that does this.

However, you would need to rewrite most of the code you have posted, if you wanted to use either of those 2 ways of running Arduino directly on an nRF5x device, rather than on an AVR device connected to a Nordic device

This is Arduino code, you cannot run this directly on the nRF devices. Why are you not getting this to work on your Bluefruit LE board?
