be necessary to confirm RF performance. Testing over analog and digital interfaces is also
unnecessary during an OEM production test.
OEM manufacturer testing should ideally focus on:
• Module assembly on the device; it should be verified that:
o Soldering and handling process did not damage the module components
o All module pins are well soldered on application board
o There are no short circuits between pins
• Component assembly on the device; it should be verified that:
o Communication with host controller can be established
o The interfaces between module and device are working
o Overall RF performance test of the device including antenna
In addition to this testing, OEMs can also perform other dedicated tests to check the device. For
example, the measurement of module current consumption in a specified operating state can
identify a short circuit if the test result deviates that from that taken against a “Golden Device”.
The standard operational module firmware and test software on the host can be used to
perform functional tests (communication with the host controller, check interfaces) and perform
basic RF performance testing. Special manufacturing firmware can also be used to perform more
advanced RF performance tests.
8.2.1 “Go/No go” tests for integrated devices
A “Go/No go” test compares the signal quality of the Device under Test (DUT) with that of
“Golden Device” in a location with a known signal quality. This test can be performed after
establishing a connection with an external device. A very simple test can be performed by just
scanning for a known Bluetooth low energy device and checking that the signal level (Received
Signal Strength Indicator (RSSI) is acceptable.
☞ Tests of this kind may be useful as a “go/no go” test but are not appropriate for RF
performance measurements.
Go/No go tests are suitable for checking communication between the host controller and the
power supply. The tests can also confirm that all components on the DUT are well soldered. A
basic RF functional test of the device that includes the antenna can be performed with standard
Bluetooth low energy devices configured as remote stations. In this scenario, the device
containing JODY-W2 and the antennas should be arranged in a fixed position inside an RF shield
box. The shielding prevents interference from other possible radio devices to ensure stable test
results.
