What code have you added to log the advertising packet? And to retransmit it? It should just be a matter of extracting the data from the received package, and apply it to the current advertising.

You may get faster and better help if you post a new ticket with your questions, instead of posting in an old, slightly related ticket.

I've already solved this error and I'm running the application. But I still haven't been able to print the received advertising in the log, I just print the advertising address as the original code. How could I do this? I would like to print the advertising received and also retransmit it, could you help me?

It would have been a very comprehensive SDK if it should include example code for every customer's use-case.

To save you some work, I have created an example combining the scanning from ble_app_beacon_c and advertising from ble_app_beacon example. It will report any advertising packet received, not just iBeacons. You must do the work to parse the advertising data to get the relevant packets for your use-case.

Hello,

I know this topic is old, and doesn't use the same SDK I'm using (17.0.2) but I'm very interested in the posted code. When compiling I am getting the following error:

Output/Release/Obj/ble_app_blinky_c_pca10056_s140/ses_startup_nrf_common.o: in function `InitializeUserMemorySections'

How could I solve this? I intend to read the advertising from nearby devices, and retransmit these advertising with a higher power on the tx.

Furthermore, I noticed that the code scans, but does not print or store these advertising, what could I change in the code to accomplish what I intend? Thank you very much!

[quote user="AkshayEnmaz"]I went through the code but i dont see the scan initiated in main(). where exactly can i find the scan function?[/quote]

It is initialized and started right after advertising init in main():

    advertising_init();
    advertising_start();
    scan_init();
    // Start execution.
    NRF_LOG_INFO("Beacon scanner+advertiser example started.");
    scan_start();

[quote user="AkshayEnmaz"]Also i could not locate ble_app_beacon_c in the sdk is it available in any specific version of SDK?[/quote]

Sorry, I intended to write ble_app_blinky_c.

Thank you for your quick response. I went through the code but i dont see the scan initiated in main(). where exactly can i find the scan function?

Also i could not locate ble_app_beacon_c in the sdk is it available in any specific version of SDK?

Specifically looking for ibeacon advertising and reading simultaneously.

That does not have the required example. I am looking for ibeacon transmitter and receiver specifically

Thank you Turbo J will check right away

Yes, the NRF52832 can advertise (as a beacon) and scan for others in the same application.

There are some examples in the "ble_central_and_peripherial" directory that one could use as a starting point.
