I'm currently working on a BLE device. This device has no screen nor keyboard. It is using a STM32L0 and is connected to an application on android.

 

I want to make a DFU (device firmware update) via bluetooth (OTA) so I can change the version of my product in a simple way. I would like to have my application giving via BLE packets of the new version of the firmware.

 

How can I process to do this ?

What do I have to do from each side of the game ? (android and my product)

 

I wanted to upgrade the firmware first (in order to try) into a Nucleo IDB05A1 with the L073RZ and an app (NRF connect) but still no results.

 

I've looked in a lot of different website but with no effective results ... this video is what i want but it's not at all in connection with my products ...
