File Transfer in DFU mode

[milav]

Hello

can we do JPEG file transfer in DFU mode instead of .Hex File?

Thank You

I don't fully understand the question. I don't see how you would transfer JPEG files in DFU mode, as DFU is just used for upgrading the firmware of the device (DFU = device firmware upgrade). If you are referring to sending JPEG files over BLE, then here is a good link to get you started.

is there any possibility to transfer Byte array Data in DFU mode?

Byte array means => Image data to byte array data...

array of resolution.

So essentially, you just want to send a jpeg file over a Bluetooth connection, right? Are you trying to send this image from a nrf52dk to a smartphone or vice versa? DFU is for updating the firmware of the device (for example a Nordic Thingy:52). It is not made for transferring other types of data than the firmware of the device. Have you taken a look at this website yet? When they say "firmware image", they do not mean an image like a jpeg file for example. They essentially mean the hex or zip file for performing the device firmware update.
