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

No, pc-nrfutil v0.5.2 supports legacy BLE and serial DFU packet generation, but you can only perform serial DFU with v0.5.2. The ble option was not added until v1.5.0.
