Add Buttonless DFU service to my Application Code

[KrishNa]

Hello,

I need to add firmware update process via air to my NRF 51822 device that runs application code on stack 12.2. How can i achieve this?

1. Do i need to add buttonless DFU library (from Experimental_Buttonless_DFU example) to my application code? or i need to compile it seperately and load it into flash seperately without disturbing my application code?

2. After entering into Bootloader mode, how can i send my updated application code via bluetooth over air?

If you have any detail documentation available for doing the firmware update over the air, please provide us.

Regards, Krish

Hi,

1. Yes, you need to add the buttonless DFU library to your application code.
2. Check out this blog post about getting started with DFU.
