☞ Although a Bluetooth scan and subsequent comparative signal test approach is appropriate for
“go/no go” evaluation, this type of testing does not measure RF performance.
A basic RF functional test of the device that includes checking the antenna can be performed with
standard Bluetooth low energy devices configured as remote stations. To obtain stable test results
and prevent possible interference from other radio devices, the device containing the NINA-B4 series
module and antenna should be arranged in a fixed position inside an RF shield box.
