Bluetooth Low Energy (BLE) is a short-range data transmission technology thatis used for multimedia file sharing, home automation, and internet-of-thingsapplication. In this work, we perform packet error rate (PER) measurement andRF testing of BLE receiver in the harsh electromagnetic environment and inpresence of RF interference. We check the PER performance in the line-of-sight(LOS) and non-line-of-sight (NLOS) scenario in absence of any interferingsignal and in presence of wideband WLAN interference. The BLE PER measurementsare conducted in a large reverberation chamber which is a rich scatteringenvironment. Software-defined-radio has been used to create BLE communicationlink for PER measurement in LOS and NLOS configuration. The BLE PER is measuredboth in the presence and in absence of WLAN interference. Our measurementresults show a higher PER for uncoded BLE PHY modes in NLOS channel conditionand in presence of wideband interference. Whereas coded BLE PHY modes i.e.LE500K and LE125K are robust to interference with lower PER measurements.
