How to change scan target name based on SDK v15.2.0 or compare the target name and make the connection by FW

[Stanley Chen]

Dear Sir,

       Good day.

       I was able to determine the peripheral devices which I need to connect based on sdk v12.2.0. I can compare the adv name and device name during BLE_GAP_EVP_REPORT state. I can make the connection to the device or ignore to search the next by the result of target name comparation. I used the driver API "sd_ble_gap_connect" to connect to device.

      Now, I am developing an application to support 5 more devices with a different name based on sdk v15.2.0. I am aware that there was no such as the process on sdk v12.2.0. The new sdk create a subroutine to handle scan process by  "NRF_BLE_SCAN_DEF(m_scan); ".

      Is there any way or how to implement my functions into sdk v15.2.0 to do the device target name comparation and to connect the device by the result of comparation?

Sorry, I forgot to mention. I used the driver API "nrf_ble_scan_all_filter_remove" & "nrf_ble_scan_filter_set" to replace the target name. But it will cause system reboot.

Hi Stanley,

Yes, using nrf_ble_scan_filter_set() and passing the target name as a parameter is the correct approach for connecting to a device based on the advertising name.

Have you enabled the log module? Is any more information printed out such as the error code?

You can use the ble_app_blinky_c example as a reference on how to filter devices based on advertising name.

Hi Jared,

      Thank you for the quickly reply. 

      The following is the log message after I tried to set a new target name. every time. As you see, it is difficult to know what happened during the target changing. 

      I will check the example you advised and see.

Hi,

What IDE are you using?

If you're using SES can you rebuild the project in Debug mode and re-flash it your device? 

Is the log more verbose this time?

regards

Jared

Hi Jared,

    Yes, I am using SES IDE to develop the application. The following is the message came from system after reboot issue happened. I also posted my FW for your reference.

     Is there anything I can check or try to do?

Hi Jared,

     I have checked the sdk application ble_app_blinky_c you suggested. Unfortunately, I didn't see anything else related to devices filtering. I assume that the process of device name filtering could be in ble_advdata.c, calling ble_advdata_name_find. If so, how do I implement it in application code?
