User Mode (WiFi)
Boot up PC or NB with the flash installed Linux OS.
5V for EUT from the power supply.
Type “sudo su” on Terminal in Linux to get root authority. EUT could be controlled if “mmc0: new high speed SDIO card at address 0001” is shown after typing “dmesg.”
Type “cd /usr” and then “insmod wlan_mt7663_sdio.ko” to enable WiFi function of EUT. 
Link to AP with another PC or NB through Ethernet cable, open DHCP function in it and record the IP address.
Click WiFi icon on the upper-right corner on Linux and disable WiFi. 
After disabling WiFi, then enable Wi-Fi, and Wi-Fi Networks (Intel….) and Wi-Fi Networks (MediaTek) would be visible. The Wi-Fi Networks (MediaTek) is device name of EUT. 
Select the SSID you would link to by Wi-Fi Networks (MediaTek). 
Click Connection Information, check the IP address and record it. 
Copy iperf tools for Linux on Linux Desktop and then use the command below to copy the tools in usr file.
cp /home/ubuntu/Desktop//iperf /usr/
Use the command below to install the tools in cd /usr path. apt install iperf
Enter the command below. chmod 777 iperf
Enable the function for possible applition as below on the 2 PCs or NBs. iperf client side
- iperf -c IP -t 10000 -i 1
- iperf server side
- iperf -s -i 1
Ping function is also usable and ctrl+c could stop the ping function. ping IP
cTX/RX (EDR-BT2.0)
Boot up PC or NB with the flash installed Linux OS.
5V for EUT from the power supply.
Type “sudo su” on Terminal in Linux to get root authority. EUT could be controlled if “mmc0: new high speed SDIO card at address 0001” is shown after typing “dmesg.”
Copy “btmtksdio_user.ko” file onto Linux Desktop and use the below command to copy “btmtksdio_user.ko” in the “usr” file.
cp /home/ubuntu/Desktop/btmtksdio_user.ko /usr/
Search “BT device” by the below command. modprobe hci_uart insmod btmtksdio_user.ko
Pair EUT to the BT device to be linked as shown below. 
After pairing, check the MAC address of the BT device in Bluetooth Settings.
Use the command “hciconfig” to check the hci number of EUT. For each number shown “Bus:
SDIO”, it would be the one of EUT. 
Replace MAC (such as B8:D5:0B:2E:30:48) and hci number (such as hci1) with the actual ones in the below command and the ping function with BT link would be enabled. while [ -z `pidof l2ping` ]; do sudo l2ping -i hci1 B8:D5:0B:2E:30:48; sleep 3; done

The Land Pattern and Dimensions should be in compliance with USI’s Standard PCB Design. The characteristics of products may vary depending on the pattern drawing method, grounding method, land dimensions, land forming method of the NC terminals and the PCB material and thickness. Therefore, be sure to verify the characteristics in the actual set. When using non-standard lands, contact Universal Global Scientific Industrial Co., Ltd. Beforehand. 
USI uses various test mode programs for test set up which operate separate from production firmware. Host integrators should contact USI for assistance with test modes needed for
module/host compliance test requirements.
The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification. If the grantee markets their product as being Part 15 Subpart B compliant (when it also contains unintentional-radiator digital circuity), then the grantee shall provide a notice stating that the final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter.
Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body.
