Buttonless Ble DFU update via Esp32

[erifat]

Hello
I want to put nordic device into dfu mode via esp32. I reviewed the documents. I put the nordic device in dfu mode from the phone.
Likewise, I am sending the data over Esp32, but I could not succeed.

Could you help?

Hello,

After enabling indications on the esp32, can you try to add a delay before you send the "Enter DFU mode" opcode? Also, do you know why the esp32 client is enabling the indication twice, and why it terminates the connection before it has received the indication?

Best regards,

Vidar

Hello
I was able to put the nordic device into dfu mode via esp32. I follow the steps in the diagram. I can't get the PNR success packet. Why could it

Can you upload a sniffer which shows when you are sending the PRN packet? And is it only the PRN packet you don't get a response to?

Hi, 

When I send 04 for execute, I get error 08. where am i doing wrong?

DFU_mode_snif.pcapng

thank you for your support.

Hi,

Error 0x8 corresponds to NRF_DFU_RES_CODE_OPERATION_NOT_PERMITTED and it looks to be returned from nrf_dfu_req_handler.c::on_data_obj_execute_request() in the bootloader. Are you able to debug the bootloader while during DFU to confirm this? And does your bootloader have logging enabled?

I am trying to update via esp32. Unable to logging in my code.

Why is the PNR packet not coming?

What could be causing this problem. How can i solve it.


Best regards,

[Vidar Berg]

Yes, I understand you are trying to implement the dfu controller on your ESP32. My question was if you had some way to debug the nRF to help understand why the execute command failed.

You mean PRN? If so, you need to enable it through the "Set receipt notification" request first.

DFU_phone.pcapngthanks,

I have one more question. 
I put the phone in DFU mode and performed the update. 
But we cannot see the DFU process from the wireshark application.

[Vidar Berg]

The sniffer will stop following the device when it enters DFU mode because of the BLE address change:

Hi,

I sending dfu packages. The correct answers are coming. However, the update is not happening.
