nrf51 add ota dfu service on hrs_scanner or ble_nus example

RE: nrf51 add ota dfu service on hrs_scanner or ble_nus example

No, there is no counter in this example, but you can create a counter in main.c.

volatile uint32_t m_counter = 0;

near the top of your main.c file, and increment this when you find an advertisement packet, or an advertisement packet from a new device (depending on what you want).

ok thank you so much Edvin,

It is working perfectly nice thanx for your help.

One last question do I know how many numbers of Bluetooth scanned by the scanner? any parameter is available for that?

thank you Edvin,

Thanks for your effort.I will check with changes in my code and update you. sorry for trouble I give you.

Note that the address is LSB, so if you want to see it the same way as in nRF Connect, you must print it in the opposite order, starting from addr[5] and ending with addr[0].

RE: nrf51 add ota dfu service on hrs_scanner or ble_nus example

Edvin — Tue, 11 Dec 2018 13:21:17 GMT

Ok. I see. Well. Thank you for sending the correct project 🙂

The scanner_beacon.c/h doesn't actually forward the address to the beacon_evt_handler() in main.c. If you see in the app_beacon_on_ble_evt, you can see that it creates the event that is forwarded to the main scanning interrupt handler. It only decodes the MINOR and MAJOR values, in addition to the uuid.

I did a few modifications to your project. Now it forwards the RSSI and the address to the beacon_evt_handler() in main.c.

Attached is the main.c file, the scanner_beacon.h and scanner_beacon.c that I changed.

RE: nrf51 add ota dfu service on hrs_scanner or ble_nus example

ud23 — Tue, 11 Dec 2018 05:27:03 GMT

yes Edvin,

That is different project which used hrs_scanner example.

Here in above project I am scanning using the central nus_c service.

devzone.nordicsemi.com/.../hrs_5F00_scanner.rar

this project has the beacon_evt_handler() function its location

nRF5_SDK_11.0.0\examples\ble_peripheral\experimental_ble_app_multiactivity_beacon\hrs_scanner

How can I make space for service using service inti with memloc() function?

Thanks for your effort

RE: nrf51 add ota dfu service on hrs_scanner or ble_nus example

Edvin — Mon, 10 Dec 2018 14:38:08 GMT

Ok. I used the pca10028\s130_with_dfu\arm5_no_packs, as it was the one I found that was closest to compiling without error, but I had to add the path to ble_db_discovery.h, so I just want to check with you that I used the correct project?

After that it compiled, but nus_c_init returns 0x04, because it didn't have space for the NUS service. So am I using the correct project?

After commenting out nus_c_init() the application runs, and I can see the advertisements, but still I can't see your beacon_evt_handler() in your project. The one that you described in a previous reply:

static void beacon_evt_handler(ble_scan_beacon_evt_t * p_evt)
{
    uint32_t err_code;
	// const ble_gap_evt_t * p_gap_evt = &p_evt->evt.gap_evt;
	// const ble_gap_evt_adv_report_t * p_adv_report = &p_gap_evt->params.adv_report;

    if((p_evt->rcv_adv_packet.adv_data.major    == SEARCHED_MAJOR)
     &&(p_evt->rcv_adv_packet.adv_data.minor    == SEARCHED_MINOR)
     &&(p_evt->rcv_adv_packet.adv_data.manuf_id == APP_COMPANY_IDENTIFIER))
    {

RE: nrf51 add ota dfu service on hrs_scanner or ble_nus example

Edvin — Wed, 05 Dec 2018 14:36:14 GMT

I don't understand. You want to store the values from the advertising packet? what does your uint16_decode() function do? You can't change the values from the p_evt. This doesn't make any sense to me.

RE: nrf51 add ota dfu service on hrs_scanner or ble_nus example

do I need to decode the mac id like

 memcpy(&adv_packet->adv_data.uuid, &buffer[i], sizeof(ble_uuid128_t));
        i += sizeof(ble_uuid128_t);
        adv_packet->adv_data.major = uint16_decode(&buffer[i]);
			//  i += sizeof(ble_gap_addr_t);
       // adv_packet->adv_data.peer_addr = uint48_encode(&buffer[i],&buffer1[i]);
			  
        i += sizeof(uint16_t);
        adv_packet->adv_data.minor = uint16_decode(&buffer[i]);
        i += sizeof(uint16_t);
        adv_packet->adv_data.rssi = uint16_decode(&buffer[i]);
			  i += sizeof(ble_uuid128_t);

Please suggest thanks in advance.

Edvin — Wed, 05 Dec 2018 08:25:52 GMT

Is it possible to send the project? I haven't tested the beacon_evt_handler myself yet. It is from a quite old SDK. I have the SDK, so if you zip the project folder, it would do. Then I wouldn't have to port the logging and beacon event handler to your project.

hi edvin still getting the wrong mac address I followed the tips you given its printing the hex value for major and minor correct but MAC iD,UUID comes wrong and RSSI comes same for any beacon place.

Here the out

MAJOR=0x 1200

Nordicid=0x59

rssi=-0xc3

uuid=874713601

I made changes to code as per your suggest

static void beacon_evt_handler(ble_scan_beacon_evt_t * p_evt)
{
    uint32_t err_code;
	// const ble_gap_evt_t * p_gap_evt = &p_evt->evt.gap_evt;

Edvin — Tue, 04 Dec 2018 14:46:41 GMT

Hello,

I have not tested to verify this, but it seems like it is only a matter of how it is presented using the printf() function.

can you try to cast to the correct lengths before printing them? You must look in the ble_scan_beacon_evt_t->rcv_adv_packet types to see what it actually is.

E.g. the address are actually uin8_t hexadecimal values:

printf("Connecting to target %02x:%02x:%02x:%02x:%02x:%02x:\r\n", //removed one %x. You had 7. Also added %02x, so that it adds 0's if the hexadecimal is 0x05, for example.
			                     (uint8_t)p_evt->rcv_adv_packet.addr.addr[0],
			                     (uint8_t)p_evt->rcv_adv_packet.addr.addr[1],
			                     (uint8_t)p_evt->rcv_adv_packet.addr.addr[2],
			                     (uint8_t)p_evt->rcv_adv_packet.addr.addr[3],
			                     (uint8_t)p_evt->rcv_adv_packet.addr.addr[4],
			                     (uint8_t)p_evt->rcv_adv_packet.addr.addr[5]);

also casting to 8 bit values before printing. I believe that you get a bit random values, because you don't specify what to print.

Also, the MAJOR and MINOR values are actually correct, but here you need to "trim" the values as well.

4608 = 0x1200

13312 = 0x3400.

Try to print:

printf("MAJOR = %02x\n", (uint16_t)p_evt->rcv_adv_packet.adv_data.major); //note the %x

Best regards,

Edvin

Hello,

If you look in the adv_packet_t structure in scanner_beacon.h, you see that the RSSI is found in adv_packet_t p_evt->rcv_adv_packet.adv_data.rssi, just like you have in the snippet above. The "MAC" address, or BLE address is found in p_evt->rcv_adv_packet->addr.addr[0] to addr.addr[5].

Do you have the beacon_evt_handler in your application? I am asking because I couldn't see it in your project.

RE: nrf51 add ota dfu service on hrs_scanner or ble_nus example

Edvin — Mon, 03 Dec 2018 12:53:21 GMT

Ok. I see.

If you try to run your example in Keil. Try to disable your optimization. Go to your project settings (Options for target) -> C/C++ -> Optimization -> Level 0 (-O0). While you are there, add DEBUG to your Preprocessor Symbols.

Then recompile your project, and set a breakpoint on line 54 in app_error.c.

Does it stop there? If so, what are your .line_num, .p_file_name and .err_code? Add error_info to watch by right clicking it, and select 'add error_info to -> Watch 1'.

You should see what file, line number and what the err_code is. Then find this place in your project, and see what function that returned this.

Best regards,

Edvin

RE: nrf51 add ota dfu service on hrs_scanner or ble_nus example

Edvin — Tue, 27 Nov 2018 14:06:49 GMT

So this issue is not related to the bootloader?

Where in nus_c_init() does it stop? Is it one of the APP_ERROR_CHECK(err_code) that receives an err_code != 0? If so, what is returned?

I can't compile your project, because you use complete paths:

#include "D:\SDK_Nordic\nRF5_SDK_11.0.0_89a8197\components\ble\ble_services\ble_nus_c\ble_nus_c.h"
#include "D:\SDK_Nordic\nRF5_SDK_11.0.0_89a8197\components\libraries\uart\app_uart.h"

I tried to fix this, but then it complained about files missing. Which project file did you use? I tried both s130 and s130_with_dfu, but none of them compiled when I changed the path for the ble_nus_c.h and app_uart.h files. It is still missing a lot of files. I just want to make sure I use the same project as you, so I don't spend a lot of time fixing something you do not use.

Also, can you check where in nus_c_init() it gets "stuck"?

Hi I programmed the Softdevice and bootloader for SDK11 with nrfgo Studio and device is advertising also and connect the device and do DFu.

But for attached file stucked at nus_c_inti() function. I Ported nus service in sdk 11._ble_peripheral/ble_app_hrs

RE: nrf51 add ota dfu service on hrs_scanner or ble_nus example

Edvin — Tue, 27 Nov 2018 13:13:12 GMT

Yes. The bootloader from SDK11.0.0 and SDK12.3.0 are different. If you use the bootloader from SDK12.3.0, you will have to use the softdevice from SDK12.3.0 as well. So this is only if you have not come too far in the development.

Did your application advertise before you added the DFU service? I can't test your application. If you want me to, send the entire project folder, including the project file (Keil application file).

And I didn't understand your answer, but did you flash the bootloader before running the application? How did you program the application? Did you do it via DFU, or the programmer? if programmer, did you use nrfjprog, nrfutil, nRFgo Studio, or your IDE (keil?)
