Hi,

To be able to get RSSI from nearby devices, the devices will have to transmitt something that your central can receive. If you setup the phone to do BLE advertising like a peripheral device, you can get the RSSI from the advertising report that you receive with the BLE_GAP_EVT_ADV_REPORT event in the ble_evt_handler in the central examples. You can print the RSSI value using the following line:

NRF_LOG_INFO("RSSI: %d", p_ble_evt->evt.gap_evt.params.adv_report.rssi);

Best regards,

Jørgen
