I would like to know how to see in which channel (37,38,39) the BLE device is advertising its data by using nrf52840?

Thank you so much, just one more question, I can print the values on the terminal by NRF_LOG_INFO, how can I save them on a text file directly from from main.c not from terminal?

Hello,

I highly recommend to buy a new nRF52840-DK, the preview kit (likely containing early hardware revision) is no longer recommended for development.

If you open a BLE central example in nRF5 SDKv15 I believe this is simply doing it like this:

        case BLE_GAP_EVT_ADV_REPORT:
        {
            int8_t rssi = p_gap_evt->params.adv_report.rssi;
            uint8_t ch_index = p_gap_evt->params.adv_report.ch_index; 
            
            on_adv_report(&p_gap_evt->params.adv_report);
        } break;

Best regards,
Kenneth

thanks for your reply, it is better to ask my question like this: is there any example code (compatible with nrf52840 preview DK) that give me, the ble rssi and advertising channel in the same time?

Hi,

I am not aware that this is possible in Linux, but it you can provide what hardware and linux lib you are using, then maybe your question will get search hits by others looking for the same or may have an answer.

Best regards,
