Seeking an nRF51 or nRF52 working application (S130) with observer callback

[Solomon]

Where can I find a working application that has an observer callback function (not a beacon) . this application must have also the broadcaster callback function.

Please have a look at the ble_app_hrs_rscs_relay example in the ble_central_and_peripheral folder in SDK 11. This example on GitHub may also be of interest, it is made for an older SoftDevice and SDK though.

Can you please specify in which function can I set a breakpoint to get the data of another advertising node?
