nrfutil v0.52 dfu serial / ble - HCI packet in terminal

[Vicnet]

Hi,

I'm using nrfutil to update my nRF52832.

I change target from nRF51822 to nRF52832 and I want be able to bootload my target through own master.

In past, I used hci_dfu_send_hex.py in verbose mode to convert hex file in HCI packet frame.

I would make the think nrfutil.

Can you tell me how can I print in console HCI packet into dfu_transport_serial / send_packet() function?

DFU based on SDK 11.0

Could tell me if the nrfutil v0.52 is able to make DFU BLE OTA ?

When I get help with command: nrfutil dfu ble --help. The ble command is not available.

HCI packet generated.51b

I modify the nrfutil code v0.52 to add BLE OTA DFU functionality.

I have an error during "compilation":

  File "nordicsemi/__main__.py", line 346, in ble
    ble_backend = DfuTransportBle(serial_port=str(port),target_device_addr=str(a
ddress))
TypeError: Can't instantiate abstract class DfuTransportBle with abstract method
s get_last_error, get_received_response, is_waiting_for_notification, send_contr
ol_data, send_packet_data

main.py
Any idea?

I found the solution to generate HCI packet. I have removed the communication protocol BLE / UART and replace sending abstract method by printing packet in terminal

Do you mean generating a firmware packet(i.e. zip-file) for BLE OTA DFU? If so, then you can do that with nrfutil v0.5.2, but you cannot perform the actual update using nrfutil. You have to use our nRF Connect or nRF Toolbox apps for Android/iOS.
