CI230X CE Certification Test Method¶
Test Preparation¶
Before conducting this test, please first check โCI-E05GT02S_MBEvaluation Kit Description.All our RF tests are based on CI-E05GT02S_MB development board suite.
Hardware Test Preparation¶
โ CI-E05GT02S_MB evaluation kit 2 PCS
โ CI-E0XGT02S module 2 PCS
โ One USB Type-C data cable
โ USB-to-UART programming tool
โ Several DuPont lines
Software Test Preparation¶
โ Programming test firmware: basic RF test programming CI230X Fixed Frequency Test Firmware.
โ Installation of USB-to-UART programming driver: ensure that the serial port drive has been correctly installed. If the serial port is not recognized, it is recommended to install the appropriate driver manually based on the chip model used in the USB-to-TTL Tool
Test Method¶
โ The DUT to be tested is a module or development board based on CI230X chip.
โ During the test, the PC sends the corresponding ATE test command, and the PC interacts with the DUT through serial port to configure various test modes.
โ If testing with the CI-E05GT02S_MB evaluation kit, the USB-to-Serial circuit is already onboard. Simply place jumper caps on PE2 and PE3, switch the UART selection switch to the “Wi-Fi” position, and connect the board to the computer using a USB Type-C data cable.
โ If testing the CI-E0XGT02S module independently, the USB-to-TTL must be connected to the moduleโs PE2 and PE3 pins, and 3.3V power and GND must also be connected to the module.
โIt is necessary to prepare a complete prototype of 1PCS for radiation test; 1PCS cut wire is used to disconnect the antenna from the matching circuit and connect the cable wire to the matching circuit for conducting test.
โ Open the serial port programming tool. It is recommended to use SSCOM or other serial debug tools. Set the baud rate to 115200, select the corresponding COM port, and then configure the test command according to the subsequent commands in this article to test each mode.

Adaptive Test¶
The test command is sent to the module through UART, and the module is connected with the integrated tester. The comprehensive tester used by the general certification laboratory is CMW500.
Enter the command:
AT+CWJAP=”CMW SSID”,”CMW password”
Example: AT+CWJAP=”CMW500”,”12345678”
Blocking Test¶
Blocking test (receiving blocking test) in CE certification is divided into two parts: Wi-Fi Blocking test and Bluetooth Blocking test. Bluetooth Blocking test uses BQB to test
Wi-Fi Blocking Test
¶
The Wi-Fi blocking certification preparation is the same as the adaptive test.
Bluetooth BQB Test
¶
Bluetooth BQB test requires flashing: CI230X BQB test firmware
Bluetooth BQB authentication is generally conducted. Disconnect the antenna, connect the RF cable of the test prototype to the coaxial line of the test equipment. Generally, the test equipment is CMW500, set the Bluetooth HCI mode, connect to the instrument, and perform subsequent BQB tests.
