nRF5_SDK_12.3.0_d7731ad - BLE Peripheral:Eddystone Beacon Application - cannot connect

NordicHam

I was able to successfully make the BLE Peripheral Eddystone Beacon Application in "nRF5_SDK_12.3.0_d7731ad" in Windows 7 32-bit (pca10040), using GNU Tools ARM Embedded version "7 2018-q2-update".

I used nRFgo Studio-Win32 version 1.21.2 to program my nRF52-DK with the hex file, as well as S132.

I can view the app on "nRF Beacon for Eddystone" on my Moto G5 Android 7 phone which has the latest kernel and patch.  However, I cannot connect to it, the progress wheel keeps rolling.  Referring to:

http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.gs%2Fdita%2Fgs%2Fnordic_tools.html&cp=1_1

I am never prompted to "Enter the beacon manufacturer lock code" on the Android app.

When I press button 1 on the DK, LED3 illuminates solid, but when I press Connect on the Android app, LED3 switches off, LED2 illuminates solid and LED1 again starts flashing, as if somehow the DK goes back to Broadcast mode.

Any ideas?  I can successfully launch the Eddystone URL using other Android BLE apps.

Thank you.

    Yes, I tested this using a Samsung smartphone using Android 7.0 and Android 8.1.0, and it works as expected.

    Is there any particular reason that you are working with an older version of the nRF5 SDK? Maybe you could test the latest nRF5 SDK (currently SDK v.15.2.0)?

    Best regards,

    Thank you for the feedback Joakim,

    I programmed my nRF52-DK with the following pre-compiled hex:

    D:\Nordic\nRF5_SDK_15.2.0_9412b96\examples\ble_peripheral\ble_app_eddystone\hex\ble_app_eddystone_pca10040_s132.hex

    Same behaviour on my Moto G5 - when I click connect on the app, the progress circle goes around forever and never connects...

    Best regards

    Hi again.

    Thanks for testing the new SDK.

    Could you try erasing the chip before reprogramming the ble_app_eddystone_pca10040_s132.hex file?

    Also, try turning off bluetooth on your phone for around 30 sec. before testing the example again.
    Make sure that you follow these instructions when testing the example.

    Do you have some logs or maybe a sniffer trace from when you try to connect to the beacon?

    Best regards,
    Joakim

    Hi Joakim

    I did first erase the DK with nRFgo Studio 1.21.2.10, and then programmed it using the hex file.

    Waiting 30 seconds before turning on BT did not make any difference.

    I am using the test instructions as you've provided - I never reach step 6.

    I used Sweetblue to capture a log on my phone, as attached, hopefully it helps

    Hi.

    I didn't see anything from the Log that indicates what the issue is.

    I'll keep digging and see if I can find what the cause of this might be.

    Best regards,
    Joakim
