Failed to perform OTA DFU using nRF Toolbox DFU 4.2 for SDK11 & SDK10

[daniel77]

I am using IOS nRF Toolbox 4.2 DFU function on nRF51 DK PCA10028. I followed the tutorial here.

1. Use nRFgo Studio to erase all.

2. Use nRFgo Studio to program softdevice s130_nrf51_2.0.0_softdevice.hex (SDK11) s130_nrf51_1.0.0_softdevice.hex (SDK10)

3. Program bootloader using Keil dfu_dual_bank_ble_s130_pca10028 (SDK11 & 10) with nrfjprog as external programming tool.

4. I send the program via email to copy over to nRF Toolbox \examples\dfu\hci_dfu_send_hex\test_images_dual_bank_update_nrf51\dfu_test_app_hrm_s130.zip \examples\dfu\ble_dfu_send_hex\test_images_update_nrf51\dfu_test_app_hrm_s130_w_dfu.zip \examples\dfu\ble_dfu_send_hex\test_images_update_nrf51\dfu_test_app_hrm_s130.zip \examples\dfu\ble_dfu_send_hex\test_images_update_nrf51\dfu_test_app_hrm_s130.zip

5. I can find the DfuTarg device and perform the upload.

It shows Starting Dfu... and exit immediately. The OTA failed because I cannot find the HRM service and it only show the DfuTarg in nRF Connect.

Is the nRF Toolbox still compatible with previous legacy DFU in SDK10/11? Or am I missing something?

This should not be an issue since nRF Toolbox v4.2.0 is compatible with both Legacy and Secure DFU. When the DFU process starts, do you see a progress bar or does the DFU fail immediately after you press upload?

[daniel77]

No progress bar. Just a half second of "starting Dfu" message and it exits immediately after I press upload. I have tested SDK12.1/12.2 DFU bootloader with same method and they are fine. I was wondering any change of nRF Toolbox requires the old SDK .zip to be updated, perhaps to include some additional info. I was thinking of going back to previous SDK since buttonless DFU may seem more stable. I am still attempting to get the SDK 12.2 buttonless DFU to work.

Could you try to generate your own zip by compiling the hrm example with DFU support and generating a zip with the hex using nrfutil?
