TIMEOUT Error when using DFU with nRF52832 of SDK12.3

Aser

Hi
I am having a hard time implementing DFU using SDK12.3 / nRF52832 now.
I have tried so many times, but have failed a lot and have left a log similar to the next one in place of the success log.

There have been a lot of attempts, but there is just one thing I can not do.
I do not know how to change the address value of Read / Write Memory Areas.

This picture is now the "Option for target 'nrf52832_xxaa" window of the current application.

Could you tell me the start value and size value of this address?
How can I find out this value?

PS.

Correct your question.

DFU is executed using nRF52832 of SDK12.3. Finally, GATT CONN TIMEOUT Error occurs and BLE Disconnect is done.
Error 8 (0x8): GATT CONN TIMEOUT
If you do BLE Scan, the device will no longer advertise.

Tutorial went through the link below.


getting started with nordics secure dfu bootloader

The time from when the button is pressed until the TIMEOUT error occurs is about 18 seconds.
If you go to another phone, the same symptoms appear.

I tested it with Android and tested it with the iPhone and it sent the hex file, but the application does not run and the device still works in bootloader mode.

Then, after DFU is stopped, reconnecting NRF Connect Programer will draw memory area like the following picture.

My application address is set up like this.

Is this a problem?

    Yes it is this tutoral.
    I've tried it again from scratch in a new environment.
    I erased the installation and reinstalled it.
    I have a completely different log than before.
    I split the nine steps to see the log where the hex file is transferred.
    But after the last nine steps, does it end?! I wanted to, but it was not a TIME OUT error.

    All Erase & Write and proceed to DFU again, the same thing happens.
    What's wrong?

    Looks like the update was successful. Do you see your device advertising when you go back to the "Scanner" tab? The app FW on the nRF device will use the same BT address as the bootloader minus 1 so the may not be able to re-connect automatically.

    There are two symptoms.
    1. Do not advertise with DFU on Android.
    It is neither bootloader mode nor application mode.
    2. When you have DFU on your iPhone, you will receive an application and appear on the NRF Connect map.
    Advertising, however, works with DFU, and the actual operation also works in bootloader mode.

    1. But you see that it's advertising if you use your iPhone?

    2. Sorry, but could try to clarify what you mean? Does everything work with the iPhone, but not Android? 

  • 0 in reply to Vidar Berg

    Yes, that's right.
    After completing the DFU on the iPhone, I confirmed that I was advertising with DFU Targ.
    However, if you run DFU on Android, GATT CONN TIMEOUT does not work.
    devzone.nordicsemi.com/.../error-8-0x8-gatt-conn-timeout-on-android
    So the MIN_CONN_INTERVAL is set to 30,
    I changed MAX_CONN_INTERVAL to 60, but I still get the same error.
    Advertising is not done either.
