DFU using the zip vs DFU using hex ?

[ToTo]

Can you tell me waht's the difference from using DFU by "hex" and "zip" ?

Which is recommended ?

Hi Toto,

Performing a Device Firmware update(DFU) with a hex is the legacy way of updating firmware, applicable for SDK v6.x and older.

You have to create a distribution zip containing the firmware image in order to perform a DFU if you're using SDK v7.x and upwards.

Please take a look at the compatibility matrix for the nRF51, found here. It shows which SDK and SoftDevice versions that are compatible. If you do not know which version you are using, then I recommend downloading the correct SDK from http://developer.nordicsemi.com/
