Reliability test in the vicinity of other Bluetooth and WiFi devices.

[Sindre Georgsen]

Hi, 

We need to test our product for reliability when it comes to BLE connection in the vicinity of other BLE and WiFi devices. Do you have any suggestions on how to perform a controlled test? Is this something you can provide/support at your facility (we are located in Trondheim)?

Id suggest using Nordics implemented RSSI 'tracker'

use:

      sd_ble_gap_rssi_start(p_ble_evt->evt.gap_evt.conn_handle,1,2);  

and implement 

  case BLE_GAP_EVT_RSSI_CHANGED:;
    int8_t current_rssi = p_ble_evt->evt.gap_evt.params.rssi_changed.rssi;
    break;

in the ble_evt_handler

As soon as you're connected with a mobile device, the sensor will give out the current RSSI in that case. Save a thousand measurements doing exactly the same routine in different vicinities.
