Make BLE Central send firmware to DFU Bootloader

[Anitha]

Hi Goature,

We are also try to implement the same. We aren't getting any idea how to start. Refer the same thread :  devzone.nordicsemi.com/.../make-ble-central-send-firmware-to-dfu-bootloader

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,

Hi,

Please take a look at Chapter 5 (DFU Master code) in this blog post: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader

Hi Sigurd,

We already Implemented uploading DFU firmware Image from nrf_connect app to nordic peripheral device(nrf52832) by referring this link https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader.

We try to implement, upload DFU firmware image from nordic central board(nrf52832) to nordic peripheral borad(nrf52832).

1.we are not getting idea about how to split the image packet and also storing the image on central board(nrf52832).

PC > (Serial) > nRF52832(Sender) > (BLE) > nRF52832(Target).

Please give suggestion for this.

Thanks & Regards,

And Chapter 5 (DFU Master code) has some example code on this.
