WIFI/BT Support Modle：

EWM-W179M201E RTL8852BE,Wifi6: PCIe + BT5.2: USB

AIW-162BS-GI1 Broadcom AP6275P, - 40°C~85°C PCIE+UART

1、Click the network icon in the top right corner of the screen and click the line of “Available networks” to select a Wi-Fi connection (for example: Advantech for guest)

2、Enter the Wi-Fi password to connect to the device.

3、If the password is correct, the device will connect quickly.

After connection, Wi-Fi will create a net point “wlan0”.

# ping -I wlan0 www.advantech.com

BT（For example：“Mate 50 Pro”）

Step1：Click “Applications” -> “Settings”-> “Bluetooth manager”. Click the “Search” button to search for Bluetooth devices.

Step2：Right-click to select a device, such as “Mate 50 Pro”, and Connect Bluetooth.

Step3：AOM-3821 will start sending files when the receiver device, such as “Mate 50 Pro”, confirms bluetooth reception.

 

Step4：View the location and information of the sent file.
