I would like to see a tutorial that starts from scratch with just the SoftDevice and the SoftDevice API. The simplest C code that could be written. No use of existing header and source files (they are are unreadable with all of the compilated macros hiding the meaning of the code).

Is there already such a tutorial?

You must to add a FREERTOS tutorial.

Perhaps a simple list (and links to find them) of support tools (even without and IDE) that should be installed BEFORE make. Like

gcc-arm developer.arm.com/.../downloads (and create a generic link version independent like most utilities)
micro-ecc devzone.nordicsemi.com/.../ run make in the InstallFolder\external\micro-ecc\nrf52_armgcc\armgcc folder to compile the micro_ecc_lib_nrf52.a library
www.segger.com/.../JLink_MacOSX_V614h.pkg

Then make

Tutorials are generally very helpful, but they should be updated to the current stable SDK version (currently nRF5 13.0.0), as they are a bit outdated.

I'd like some tutorials about how to integrate a unit-testing tool into any project based on your SDK, e.g., with Unity (Ceedling).

I'd also like tutorials to show how to monitor some basic functionalities with GPIOs, e.g. the overall CPU activity, the working time of the SoftDevice, etc.

I downloaded some time ago from Nordic web site the PDF article: "Getting started with Bluetooth Low Energy Development".

The document is excellent summary about BLE and I'm just wondering why it is not published as tutorial in Developer Zone. Everyone starting BLE development should read it first.

Thank you so much for this initiative. I'd like to see tutorial(s) on security manager, that explains security procedure, SMP key generation methods, security mechanism (encryption, privacy, signing).

Does this answer provide enough information for you?

Can we get a tutorial to run a particular part of the code from RAM? Cheers.

Well, there's not really all that much to it.

SoftDevice:

HFCLK started by:

uint32_t running=0;
sd_clock_hfclk_request();
while (!running) 
{
    sd_clock_hfclk_is_running(&p_is_running);
}

Stopped by:

sd_clock_hfclk_release();

LFCLK is always configured when the SoftDevice running, start it by calling

SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_50_PPM , NULL)

NRF_CLOCK_LFCLKSRC_XTAL_50_PPM should be exchanged with the appropriate LFCLK from this struct.

No SoftDevice

// Start high frequency clock
NRF_CLOCK->TASKS_HFCLKSTART = 1;
while (NRF_CLOCK->EVENTS_HFCLKSTARTED == 0)
{
    // Wait for clock to start
}
NRF_CLOCK->EVENTS_HFCLKSTARTED = 0;

// Start low frequency clock
NRF_CLOCK->TASKS_LFCLKSTART = 1;
while (NRF_CLOCK->EVENTS_LFCLKSTARTED == 0)
{
    // Wait for clock to start
}
NRF_CLOCK->EVENTS_LFCLKSTARTED = 0;

Note that there is not ppm configuration in the initialization without SoftDevice, this has to be done manually.

Please make some tutorials on switching clock sources and changing clock frequencies for nRF52 with and without softdevices.. Also some more help on Low power modes is appreciated.

Thanks

A more complete tutorial on building with gcc would be useful. The existing one is not very accurate (at time of writing).

A tutorial about adding more than one service and characteristics in BLE for newbie, since lot of them finding it difficult to understand and there lot of confusion.

You communicate using serial port. There is a unity plugin that I guess helped allot with the adoption of the HC series in the Unity dev community. Link here: www.assetstore.unity3d.com/.../ Sorry I can't be of more help, I've just started learning the ropes of wireless communication protocols.

That is what i was also going to point out - if there is some integration between Unity-UART-Arduino, I see no reason why this would not work with nRF51/52, but what should be done next is probably totally up to developer - i don't know what that kind of tutorial should cover, communication by uart, driving leds or what? o_O

RE: Tutorials[Meta]

awneil — Fri, 08 Apr 2016 14:02:08 GMT

But, surely, this has nothing to do with any specific BT chip: stuff like Unity and/or Unreal just sees the platform's generic BLE API - ie, GATT profiles, etc?

And, as already noted, the HC-05/06 is "classic" bluetooth - not BLE.

RE: Tutorials[Meta]

Wojtek — Fri, 08 Apr 2016 13:46:37 GMT

How do they communicate PC with arduino? By UART or what?

RE: Tutorials[Meta]

Liviu — Fri, 08 Apr 2016 13:44:21 GMT

A quick tutorial on integrating the nRF51/52 into a real time game engine such as Unity and/or Unreal would be great — specifically for the advertising industry: interactive installations, tech art, PR stunts etc, but also for tech hobbyists. Currently, most of the advertising agencies I collaborated with use Arduino + HC-05/06 as it's the only combo that has tutorials, video demos and plugins for Unity integration.

The reason why this keyboard has a key to switch OS could simply be that it allows connecting to two devices at the same time, and you can switch between these devices using that button. Some of the key mappings may be done differently depending on OS, but I do not have the keyboard so I can not test it to check. The HID standard should not differ between OSes, but available connection parameters could differ. As far as I know the HID examples work with multiple platforms.

Hi Oyvind

maybe a very basic tutorial on nRF24L01+ with ACK payload, with all registers that must be set for a sucessfull transmissition/reception. A very basic one, supposing a simpl address, simple message, just one pipe, etc.

For example, for a 3 byte address (1,2,3), payload of 7 bytes, ack payload of 7 bytes you need:

at PTX you need to setup before transmiting:

register xxxx= yyy
register xxxx= yyy
.....

to transmit the 7 byte payload at PTX you need:

load register xxx = yyyy
,,,,
setup CE for > 10 uS

at PRX, you need to setup before receiving:

.... and so one....

*please, include CE manipulation, mainly in PRX and if there is any restriction in time that CE shoub be 0 betwen receptions, for example.

Thanks

Have yiu looked at this blog for Eclipse dev on OSX ? It has instructions for creating Eclipse project and debugging, flashing softdevice etc..

RE: Tutorials[Meta]

awneil — Sat, 05 Dec 2015 12:11:29 GMT

Yes, I'd like to see something on this!

Something that really explains what Bonding is, how & why it's used, why we might need it, when we might not, etc, etc, ...
