Hi,

We found enable wifi has impact on the received BLE RSSI values.

The test is pretty simple:

Make the wiced device scan the nearby tags. (Put a tag in fixed position as reference for the test)

When wifi is disabled, the observed ble tag RSSI looks fine. (use wiced_bt_ble_observe() or wiced_bt_ble_scan())

When wifi is enabled (either join a AP or wiced device being a AP), the observed ble tag RSSI deviation becomes too large.

This issue makes the device not able to be used for detecting object location.

Tested on USI-BM22 (43438) and SPIL-N08 (4343W) with latest SDK.
