How to implement timeslot observer based on ble_app_hrs?

[eddy]

Greetings,

I have a peripheral (S110) , when it is connecting to a central, it also need to scan another broadcaster (beacon) to obtain its RSSI and send to the central. So I tried to use the Nordic GitHub project Timeslot Oberver example on ble_app_hrs. So I copied the code from \nRF51-multi-role-conn-observer-advertiser-master\observer to \ble_app_hrs , and merged the two main() functions. But it didn't work. And I found if i commented advertising_start(), it can print advertising_report. And if i uncommented advertising_start(), it printed nothing. What's the problem and how can I do? Many thanks!

Hi,

You can try the experimental_ble_app_multiactivity_beacon example in SDK v7.x where you can find a advertise and a scanner example that combine with hrs profile.

How do you handle the event when the advertising packet is caught ? Note that if you take too much time in the event handler you will have a hardfault.

Could you run the firmware in debug mode and add a breakpoint in the assert handlers, such as in softdevice_assertion_handler() and find which line number, and file name caused the issue ?

You can test by doing nothing but toggle a LED when receives the advertising packet to see if the issue remains. If it doesn't crash I would suggest you to use the scheduler, or set a flag when receive the advertising packet, instead of doing the processing inside the event handler.
