BG951A-GL – Dial-up PPP testing from Windows

For this test, Windows 10 screens are used and the Quectel EVB and BG951A-GL TE-A (carrier board), as shown below:

EVB with BG951A-GL TE-A board installed.

For this test power has to be supplied to the main board via the USB power supply socket, or the 5V connector. 5V Power also needs to be supplied to the TE-A board via one of the USB connectors at the top edge as in the photo, e.g. the UART CLI port. The data connection is via the Main UART. The UART to USB cable is included in the EVB kit, connects directly to PC.

Configure the EVB modem

Setup the main UART for HW handshaking and 115200 baud:
AT&K3 // HW handshaking

Attach on the network, as example below where I’m using our QCom  serial terminal application:

Then disconnect, close the COM port.

Configure Windows Dial-up

From Windows network and sharing centre, setup a new connection or network, connect to a workplace.

Click on Next
Click on Next
This should take you to next screen
This should take you to next window:
Enter the Dial-up *99 and modem name, click on Next.
Can leave this blank, click on Create button.

Create the modem in Windows

Setup a 28800bps modem in Windows, with the same 115200 baud that you used in the terminal

Create a new modem instance, click on Add
Click on Next button.
Select this 28800 bps modem, click on next
Select the COM port that is your EVB Main UART, from Device Manager. click on Next button.
Click on Finish button.
In Device Manager, the modem should now appear.

Link the Windows modem with the Dial-up

Note again, the PPP number to dial is *99

With the previously created dial-up under Windows -> Settings -> Network &Internet, dial-up, connect and check the properties as below.

In the BG951 properties, “Connect using” drop down box, select the new modem previously created, the Standard 28800 bps. Then click the configure button as shown.

Using the AT command terminal (QCom app. in this example), ensure the BG951 to registered (attached) state on the network, ready to connect. Disconnect the AT command terminal.
From the settings, dial-up, click on the connect button, then the Dial button.

If all goes well, you should see the modem move to connected state!
