Unable to run test image BLE DFU

[Sudhir Foujadar]

Hi,

I want to develop DFU using BLE. I have started with test image given in the example folder.

I have nrf52480 device , using S140 softdevice. I have followed these steps for DFU update.

1. Open nrf connect and erase complete chip.

2. Add hex file -> sd_s140_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex

3. Write to the chip.

4. Disconnect nrf board. 

5. Open nrf connect mobile app, i am able to see Nordic Buttonless. Connect to that BLE and set char to bootloader mode.

6. Connect to DFU test and open the select zip file.

7. Select 1st option ZIP file ->hrs_application_s140.

8. Mobile app shows following Starting DFU and then the graph is blank noting data is sent and after somtime DFU test is diconnected.

Can you help me with the steps to do it correctly.

Regards

Hi Sudhir,

What is the SDK version you are using?

What is the phone OS, Android, or iOS? 

8. Mobile app shows following Starting DFU and then the graph is blank noting data is sent and after somtime DFU test is diconnected.

Are you able to provide the log of the nRF Connect mobile app after you run into the issue?

You could double-check the hrs_application_s140 is from the same SDK version/folder as the sd_s140_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_without_bonds.hex.

nRF5 SDK v16.0.0

Phone is Android 

The Hex file is from same folder.

The highlighted hex file downloaded in SOC.

After downloading the memory map in right is shown by reading it

Hi,

Very happy to inform that now that same process is working and its updating. Thanks for your help.

Also would like to keep this thread open for further enquires.

Can you let me know how does the ble stack work , in terms of which function are called and its respective events. I am confused why are multiple events triggered or needs to register.

Not sure how much you know about the BLE. I would suggest you take a look at our Bluetooth low energy tutorials. 

If you have further questions regarding the ble stack, please create a new support case. This is away from the original scope.
