Using NRF52832 as eddystone scanner

[MLai]

Hi all,

I am working on eddystone scanner and I follow this post to start with. However, I have some problems:

1. The device isn't scanning without any modification of the code. In the ble_app_uart_c programe, scan_start in main is called but nrf_ble_scan_start isn't working.

2. The post said using ble_advdat_uuid_find() can find the uuid, but I don't know where the function is from or it is deprecated in sdk 15.2.

3. I added BLE_GAP_EVT_ADV_REPORT case in my Handler, but I want to know the function on_adv_report is a self-defined function or not?

Best regards,

Marco

Are you getting any error codes?

What debugging have you done to find what's going wrong?

Did you remember to program the SoftDevice?

Thank you for your reply. I have found the problem is that nrf_log_info is not working, and after I use printf, I can see the scanner working and always enter BLE_GAP_EVT_ADV_REPORT. Sorry for making this silly problem. Another question is that is the  BLE_GAP_EVT_ADV_REPORT is enter when it detect a bluetooth device? And can I filter the device by modifying scan_param?

Yes, BLE_GAP_EVT_ADV_REPORT is the event when an advertisement is received.

Details of the scanning module are here:

I found I need to set the filter at nrf_ble_scan_filter_set, I want to know how I should set the uuid filter. As the example using nus, which it set the filter uuid to 0x0001 and what is the type? Is that the type of the eddystone packet same as nus? Moreover, if the packet matches the filter, it will connect to the device, if I want to avoid connection, what should I do?
