How to do nRF52832 mutilink OTA?

[Alice]

Hi,

I'm using nRF5_SDK_12.0.0_12f24da and s132_nrf52_3.0.0_softdevice to do the mutilink and it's almost ready. We want to do the OTA on it. I think the mutilink is working as center, so I need to add a peripheral on it, right? But I don't know how to do it. Is there any example or document that I can refer to? Thanks.

Best regards, Alice

Hi Alice,

Yes, it's possible. The S132 can do both central and peripheral. You don't need to "add peripheral". All you need to do is to flash the bootloader (like a normal DFU setup) and find a way to switch from your application to the bootloader. After that the bootloader will take care of the DFU process.

I would suggest you to test with our buttonless DFU application here to get familiar with the bootloader, how to do Secure DFU and on how to switch to the bootloader.
