Make BLE Central send firmware to DFU Bootloader

[Goature]

Hello all!

I've been researching DFU over BLE, between a central and a peripheral.

The peripheral is possible to upgrade over the DFU Bootloader. I've tried upgrading this unit with the MCP from nordic, and it works.

However, when i try to initiate the DFU on the peripheral, using my central device, by writing 0x01 to the DFU Control Point of the peripheral - i receive {0x10, 0x01, 0x06}. Does the 0x06 mean that the process was unable to start? (infocenter.nordicsemi.com/.../bledfu_transport_bleservice.html

What am I doing wrong here? Is this not the way to start the process?

Hi Goature,

We are also try to implement the same. We aren't getting any idea how to start.

1.how to upload the firmware image from central(nrf52832) nordic device to peripheral nrf52832 device.

2.how to split the image packet and also storing the image on central side?

Kindly give suggestion for our problems.

Thanks & regards,
