How to Send Device to DFU Mode using iOS SDK

[Marcelo Salloum]

Hello guys,

is there a way to send the Device to DFU mode without pressing the button? I am currently using some code from this repo.

Thanks,

Yes, you can add DFU support to your application to support buttonless entry into DFU mode. Instructions on how to do that is given in the SDK documentation here.

Also, the ble_app_hrs_SoftDevice_with_dfu_pca10028 shows how it can be implemented.

Hello Vidar,

Can you please explain, after connected to BLE device from iOS device how we can move BLE device into DFU mode. I want to know any code reference for switch into DFU mode. In my understandings after we move to DFU mode only we were able to do DFU process from Nordic Toolbox app. Please confirm. Thanks.
