Read my reply starting with "As long as it doesn't return 0, the message is not sent.".

Then look at the example found in SDK\examples\ble_peripheral\experimental\ble_app_multiperipheral.

Hi.

Thank you for your reply.

Unfortunately, I couldn't find a solution.

I don't know where to fix it.

I am a beginner and need help.

Did you solve the issue where ble_nus_data_send() returned 5?

Thank you for your reply.

The project url you used on your github.

https://github.com/jimmywong2003/nrf5-ble-multiple-role-example

Two examples were downloaded and tested on the nrf52832 dk board.

I used sdk 15.3.

I have connected nrf52832 board and iphone7 (app: nrf toolbox).

I want to send and receive data in both directions using uart terminal.

But The <ble_app_lbs_nus_its_multi-role> example doesn't seem to be normal.

I used nrf52832(pca10040/s132) board.

A. Example <ble_app_lbs_nus_its_multi_role> and the Mobile Connection Screen

<ble_app_lbs_nus_its_multi_role/nrf52832(Peripheral mode)>

In the uart terminal, I typed "data send" on the keyboard.

(Tx "DATA SEND")

<NRF TOOLBOX(ios)> (Central)

not reveive

B. Example <ble_app_lbs_nus> and the Mobile Connection Screen

<ble_app_lbs_nus/nrf52832(Peripheral)>

In the uart terminal, I typed "data send" on the keyboard.

(Tx "DATA SEND")

<NRF TOOLBOX(ios)> (Central)

reveived "data send"

There are additional issues involved.


Two NRF52832 DK boards were used.
On the first NRF52832 DK board
I downloaded the <ble_app_lbs_nus_its_multi_role> example.
On the second board I downloaded ble_app_lbs_nus.
<ble_app_lbs_nus_its_multi_role> was used in CENTRAL mode.
I set <ble_app_lbs_nus> to Peripheral.
The connection was successful.
However,
Using UART terminal
<ble_app_lbs_nus_its_multi_role> Sent data to the board.
<ble_app_lbs_nus> No data is received on the board.
In my opinion, the ble_nus_data_send () function seems to have a problem 
in the ble_app_lbs_nus_its_multi_role example.

Thanks to Jimmy, the development went smoothly.

Please, reply.

thank you.
Have a nice day

HI Cjb21,

Please tell me which example do you use from my github.

and then how to reproduce sequence .

Thank you. Where can I get a multiperipheral example?

RE: NRF52832 NUS multirole Test

Edvin — Thu, 22 Aug 2019 11:35:00 GMT

Yes. It is the reason I explained in the previous answer. You are not sending a valid connection handle into ble_nusdata_send(). Look at the multiperipheral example how it should be done.

RE: NRF52832 NUS multirole Test

cjb21 — Thu, 22 Aug 2019 11:24:46 GMT

Thank you for answer.

Found a place to return 5. Within the ble_nus.c file.

This is the statement in the ble_nus_data_send () function.

err_code = blcm_link_ctx_get (p_nus-> p_link_ctx_storage, conn_handle, (void *) & p_client);

See the screenshot below.

Thank you

Edvin — Thu, 22 Aug 2019 11:04:12 GMT

As long as it doesn't return 0, the message is not sent.

Can you check where in ble_nus_data_send it returns 5? 5 = NRF_ERROR_NOT_FOUND. It should be in ble_nus.c. Either it is

    if ((conn_handle == BLE_CONN_HANDLE_INVALID) || (p_client == NULL))
    {
        return NRF_ERROR_NOT_FOUND;
    }

or the softdevice call:

return sd_ble_gatts_hvx(conn_handle, &hvx_params);

It may be easiest to debug and set breakpoints to figure out which one it is, since NRF_LOG is not enabled by default. Alternatively you can enable it by setting BLE_NUS_CONFIG_LOG_ENABLED to 1 in sdk_config.h to be able to use NRF_LOG_INFO in ble_nus.c.

It is a bit tricky to port the ble_app_uart example to support multiple connections. You have to handle all your connection handles correctly. I suggest you take a look in the ble_app_multiperipheral example in SDK\examples\ble_peripheral\experimental\ble_app_multiperipheral.

Especially in the on_connected() funtion in main, where nrf_ble_qwr_conn_handle_assign() is called in this example. The conn handles is an array. It should be the same in your example. You can also see how it uses the connection handle in led_status_send_to_all().

Best regards,

Edvin

A. <ble_app_lbs_nus_its_multi_role> example

Returns 5

B. <ble_app_lbs_nus> example > [Normal operation example]

Returns 0

In the case where it doesn't work, what does ble_nus_data_send() return?

RE: NRF52832 NUS multirole Test

cjb21 — Thu, 22 Aug 2019 07:08:51 GMT

Hi. Long time no see.

Thanks to you,

we have confirmed the connection between the < ble_app_lbs_nus_its_multi_role> example and

<ble_app_lbs_nus> examples.

I would like to ask another issue.

I connect the < ble_app_lbs_nus_its_multi_role> example to a mobile phone (nrf toolbox / ios) and the data entered in the uart terminal does not reach the mobile phone (nrf toolbox / ios).

Connecting the example to a mobile phone (nrf toolbox / ios) and entering data into the uart terminal is successfully sent.

A. Example <ble_app_lbs_nus_its_multi_role> and the Mobile Connection Screen

<UART>

(Tx "DATA SEND")

not reveive

B. Example <ble_app_lbs_nus> and the Mobile Connection Screen

(Tx "DATA SEND")

reveived "data send"

as above I wonder why the ble_app_lbs_nus_its_multi_role example doesn't work.

Below is the project file I used.

I used sdk 15.3

devzone.nordicsemi.com/.../nrf5_2D00_ble_2D00_multiple_2D00_role_2D00_example_2D00_master.zip

Thank you. Please.

I see from the event log that you have replied, edited something and deleted a reply. Also I noticed that the original ticket text is gone. I am not sure whether this was on purpose or not, but just as you know, I can't see anything more in this ticket now, and consider it closed until you update it or reply.

NB: We can only see that something is edited, and not what the edit actually was, so the best is to reply instead of editing existing replies.

Best regards,

I assume that you use the Segger Embedded Studio (SES) projects?

Do you see the logging information in SES?

I have built and tested a peripheral example on another dk board,

My dk board does not connect to central mode.

What do you mean? It doesn't connect to a central or it doesn't connect to a peripheral? I have tested both cases, and it does. Not the phone advertising, but the ble_app_lbs_nus_its_multi_role example connects to both the ble_app_lbs_nus and the ble_app_lbs_nus_c example.

Did you do any changes to any of the examples?

You use the correct projects, right? The pca10040 ones?

Hi.

I am using the ble_app_lbs_nus_its_multi-role example.

I have built and tested a peripheral example on another dk board,

My dk board does not connect to central mode.

Thank you

Edvin — Tue, 30 Jul 2019 08:02:54 GMT

Ok. So you are using the ble_app_lbs_nus_c project, is that correct?

If so it is looking for devices named "LBS_NUS_Node".

I tested it now, and I see that the nRF Connect for Mobile doesn't actually set the name in the advertisement packets (at least for iOS). Have you tested to connect it to another DK running the peripheral project?

Best regards,

Edvin

Thank you for answer.
I am using s132 on pca10040 in version 15.3.
I am using the nrf52832 chip.

It is difficult to verify that the on_adv_rep function works
Peripheral is the uart, Central is the.
I tried to match UUID and device_name but it does not work. Help

RE: NRF52832 NUS multirole Test

Edvin — Mon, 29 Jul 2019 14:24:43 GMT

Hello,

What SDK version do you use? Can you check what the on_adv_report() does when it picks up the advertisements from the phone? You can also see inside this function what it is looking for, whether it is a UUID or an advertising name (or something else).

It is a bit hard to pinpoint exactly where it checks for this, as it differs between the different SDK versions, but do a search for "on_adv_rep" in your project, and see if you can find out what function that is called when the scanner receives an advertisement report.
