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

You just want to print the content of the HCI packet in the terminal?

Yes, I want to print the HCI packet.

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.

In 1.5.0 version, the BLE is not legacy ? Only for "modern firmware packages" ? BLE Secure?
