How to advertise with nRF52810 in order to be seen by BT4

[studzinski]

Dear Sirs,

How to advertise with nRF52810 (peripheral mode) in order to be seen by BT4 devices (Smartphones)?

Is it necessary to make a special configuration (settings)? If yes, where can I find an example?

I try to use

nrf51-ble-tutorial-advertising/nrf52-ble-tutorial-advertising/ from GitHub.

with S112 softdevice

In addition, I spent hours(days) to make run a simple advertisement, without any success.

The example I use requires usage of your board with LEDs an buttons.

BTW, all your examples are very hard to understand and are very complex... Even for a simple functionality 

On my PCB board, I have no buttons and LEDs and I cannot initialise services as you make in your example...

Could you give us a SIMPLE example, without complex event handlers, LEDS and buttons, with a minimum initialization?

I would like only be seen from a smartphone, giving only basic info as device name and product series number, nothing more...

Thank you in advance for your help

Cordially yours

Andre

Hi,

You don't need any additional configurations for a BLE supported smartphone to scan for advertising peripherals. On the other hand, that means that every device which supports BLE can scan for the peripheral, not just the smartphone if whitelist and directected advertising is not used. You can use directed advertising and whitelist if you only want to advertise to a device with a specific address. 

A good start point for developing BLE examples is our template example in the SDK. You can find it at YourSDK\examples\ble_peripheral\ble_app_template. I would also encourage you to read our tutorials on BLE, which explains how to setup advertising, services, whitelist etc. You can find them here.

Best regards

Thank you very much for your reply.

Unfortunately, your SDK examples are very complex and hard to understand, using event handlers, LEDS, buttons etc.

On my PCB board I have not LEDS and buttons.

I have already tried with your SDK example, I have even began with it, but I could not understand it.

It is my reason to ask you a simpler one.

It MUST work on my custom board, not on your proprietary board...

I need a an example of advertising with a minimum initialization and without communication (no services), not depending of hardware.

Is it possible?

Cordially yours

Dear Jared,

Thank you very much for your reply.

I am simply trying to strip unnecessary code.

My board works (advertises) well, and I use, of course, my custom board file, but without LEDS and GPIOS used by your examples...

I was talking about GPIO event handler, not about event handlers in general...

It seems, I have to use services_init() function before advertising, I do not understand why (I do not use any service). Otherwise I get run time error from also from advertising_init function.

Maybe I am wrong, I will check it once more...

Concerning error, I have copied all initialization functions from your example, so I do not understand the bug...

However, I have removed conn_params_init(), since I do not need the connection at this moment.

I would like simply to know, when such error occurs (if I plan to use connection in future).

Cordially yours

Andre

Hi,

• What error is thrown? 
• I may have misunderstood your intention, if you're not going to make a connection in the future, then I strongly suggest that you to start with the beacon example instead.

All your examples use LED/button interface, it was a main reason I asked you for a simpler one...

Really, is it impossible for you to give a simple example with a minimum code (without LEDS & buttons handlers) ?

The error 03 (internal error) is from  ble_conn_params_init(). Fortunately I do not need it, for instant...

Could you confirm that the following code sequence is sufficient for advertising?

The functions are from https://github.com/NordicPlayground/nrf51-ble-tutorial-advertising/blob/master/nrf52-ble-tutorial-advertising/main.c

                ble_stack_init();                    
                gap_params_init();                
                gatt_init();
                advertising_init();
                // Start execution
                advertising_start();

Cordially

Try this one:

1462.ble_app_beacon.zip

[studzinski]

Thank you for your simplified example... 

I will try it

I said it too quickly, alas...

Unfortunately I cannot run your example.

Keil asks for software packs, even if I use the arm5_no_packs version. I cannot understand it at all...

What have I to do in such case? What version have I to use?

What does it mean: INSTALL missing Software Packs?

Where to put files (what files) and where have I to set there paths?

As you can see on screenshot, the both files are at correct place in project tree: 
D:\Nordic_ble_app_beacon\pca10040e\s112\arm5_no_packs\RTE\Device\nRF52810_xxAA

Obviously, the compiler does not see them...

How to edit paths for project files? There is no such option in project items manager

Unfortunately, when I try to INSTALL packs as asked by Keil, the installer try to modify my default Keil configuration (not only the project).

I do not understand it at all, because I can build and run my current project using 52810 device without any additional installs of soft packs...

Anyway, the installer could not install packs (Keil site error when trying to download files)

I'm really very sorry to bother you all the time, believe me...

Simply, I am very, very frustrated, least thing takes hours, days or weeks and I have non-stop to ask questions to your development (support) team.

Why it is impossible to get some SIMPLE and working examples????

For me, your IDE (Keil) is too complicated and really incomprehensible, but I do not want to change it once more... Before now, I used several IDE, among others Visual Studio & Microchip IDE...

[Jared]

Hi,

The pack installer in Keil uvision requires you to update software packs. The update should install the missing files itself once allowed. If you're using a newer version of the SDK you have the option to use SES or gcc. Visual studio, and Microchip IDE is not officially supported. Question regarding Keil uvision should be asked here.
