Quick start guide

In this guide we used Ubuntu in order to use the PMOD-Huawei board. With the following commands you will be able to navigate on the internet via the PMOD-Huawei. These steps are equal for both version of the boards ME909s and MU709S2.

1. On the PMOD-Huawei board insert the antenna in CN4 connector

2. Insert your SIM card in the slot located in the bottom layer of the PMOD-Huawei

• Open the slot:

• Insert the SIM in the correct way:

• Close the slot:

3. Insert the jumper from PIN2 and PIN3 of the SW1

4. Connect board with PMOD interface TYPE 4 to CN6 connector

The PIN1 of the CN6 is signed with a white triangle on the board.

5. In the PMOD-TYPE4 interface are used the line in the following way:

• CTS: not used (CN6 PIN1)
• TX: used
• RX: used
• RTS: not used
• INT: at startup setted high then setted low only for 1 seconds (CN6 PIN7)
• RST: setted high
• IO7: not used
• IO8: not used
• GND & VCC: used

6. When the LED1 on the PMOD-Huawei will start to blink steadly every 1 second the module will be connected to the netowrk (feature only for MU709S2)

7. We used an device in order to comunicate via UART 3v3 to the pmod interface. For example we used minicom connecting to /dev/ttyACM0 at baudrate: 115200, 8N1
8. If all works correctly sending the command AT the PMOD will reply with OK
9. Write this command followed by enter:

AT+CGDCONT=1,”IP”,”YOUR APN”

Where “YOUR APN” is the Access Point Name of your SIM

10. Launch this AT command ATDT*99# then exit from minicom
11. With the following commands you will be able to navigate on the internet:

sudo pppd ttyACM0 115200 nodetach noauth lock usepeerdns

sudo route add default ppp0

12. Open your preferred browser and try to navigate

Warning

remember to disable your wifi connection or LAN connection if they have access to the internet

Note

If you want use Windows, install the right driver using LPCUSBlib_VirtualSerial.inf file and installing it. In this way you will have the virtual com enabled in order to comunicate with the PMOD. In this guide we don’t explain how to use the PMOD-Huawei with Windows.
