Switching between advertising and scanning in the same application

[Sarah]

Hello,

In my code I would like to switch between BLE advertising and listening nearby devices (and save their RSSI) in the same code. After each advertising period, I would like the device to scan for a short amount of time (say 1s) and then switch back to advertising again. Is this possible with Nordic libraries? If so, how should I go about doing this? So far all I can do is RUN the existing ble_app_beacon that comes with the nRF51822 on the nRF51 DK development board (which I believe has the capability to do what I said).

Thanks

Hi Sarah,

I am using this library (github.com/.../nRF51-multi-role-conn-observer-advertiser) which allows to run and advertiser (or a scanner) concurrently with the Softdevice. So, I advertise using the Softdevice S110 and scan using the observer part of this library.

If you begin from the observer example it is quite easy to add the advertising part.

Cheers

The S130 SoftDevice supports both functions concurrently.

The example app "experimental_ble_app_s130_example_c_s130_pca10028 (BLE Dual role application)" has most of the functionality.
