o The interfaces between module and device are working
o Overall RF performance test of the device including antenna
Dedicated tests can be implemented to check the device. For example, the measurement of module
current consumption when set in a specified state can detect a short circuit if compared with a
“Golden Device” result.
The standard operational module software and test software on the host can be used to perform
functional tests (communication with the host controller, check interfaces) and to perform basic RF
performance tests.
6.2.1 “Go/No go” tests for integrated devices
A “Go/No go” test compares the signal quality with a “Golden Device” in a location with known signal
quality. This test can be performed after establishing a connection with an external AP or station.
Example commands that can be used to get the signal quality are:
• AT+UBTI Bluetooth Inquiry
• AT+UBTD BLE Discovery
• AT+UWSCAN WiFi Scan
More information about the AT commands and the required parameters can be found in the
u-blox
Short range AT commands manual [1]
.
A very simple test can be performed by just scanning for a known AP on a specific frequency and
checking the signal level.
☞ These kinds of test may be useful as a “go/no go” test but not for RF performance measurements.
This test is suitable to check the functionality of the communication with the host controller and the
power supply. It is also a means to verify if components are well soldered.
A basic RF functional test of the device including the antenna can be performed with standard Wi-Fi
and/or Bluetooth devices as remote stations. The device containing the ODIN-W2 series module and
the antennas should be arranged in a fixed position inside an RF shield box to prevent interferences
from other possible radio devices to get stable test results.
