Buttonless Ble DFU update via Esp32

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?

Best regards,Esp32(Master)_Nrf(Slave) dfu.pcapng
