services changed notification. SDK 6.1

[Fabrizio]

Hi all, we have a project based on nRF51422, SDK 6.1, Softdevice S310 2.0.1. We use the bootloader for DFU services. Our problem is to send a service changed notification when the application resets to restart the system in bootloader (and then in dfu mode). We want to avoid using the refresh cache services method from the Android side, also because with iOS that is not possible. We have seen that in the new SDK (9) there is code to handle this situation but we would like to avoid porting our code in the new SDK. Is it possible and how to send the services changed notification from bootloader, (which restarts without any knowledge of the peer)?

Best regards,

Fabrizio

Not sure what is the most work. Either update to newer SDK and Softdevice, or implement service changed into the old bootloader and your application. Anyway there is a blog here and here. Where the later one describes the current DFU approach so you can see how we handle service changed.
