How do I make receiver application which scans the beacons in the vicinity ?

[Jaydev Borkar]

I have developed a beacon application which transmits the required data from an analog device. I want one more application which scans the transmitted information from the transmitter beacon . So basically we can call it as multiple beacon scanner or receiver . Is there any document related to this task ?

That would be a Central in BLE terms - so look at the BLE Central examples in the SDK ...

I have tried with Blinky example as peripheral and ble_app_multilink_central as central device. I had flashed blinky code in one module and the central code in another . The central master could control the LED's in first module. But the blinky application is service based. I am afraid beacon is not service based communication.So is there any other go ?

[awneil]

A beacon basically just advertises - so your Central just needs to scan for Advertisements, and get the Advertising Data data from those Advertisements.

beacon example:

Thanks for the link . I have used the same example to transmit the data . Now am stuck at receiving the same data using receiver .

[awneil]

As mentioned, the data is in the Advertising packets.

So look at the code which handles the Scan Report events ...

[Jaydev Borkar]

Thanks . Can you please let me know the examples which use Scan Report Events.

[awneil]

Go on.

You said you've used the ble_app_multilink_central - it has to use the events to know when it's seen an Advertisement!

Hint: look for functions with names suggesting  "event handler" ...

Use RTT or UART to put out log messages so that you can see what's happening.

So u mean I need to add ble_advertising.c , ble_conn_state.c , ble_db_discovery.c from ble_app_multilink central in my receiver project ? I see that the Multilink_central scans for the device name . Such as Nordic_Blinky . I need to change it as per my beacon name. 

My beacon name shows N/A(Nordic) . What do I give as input for scanning device name ?
