INTRODUCTION

PMOD-Huawei board has mounted an Huawei device with the possibility using SIM or eUICC interface. Using the Empire board it is possible send via virtual com AT commands. There are 2 version of this board:

  • BAEPMOD-COM-019-A01 with mounted MU709S2 device
  • BAEPMOD-COM-021-A01 with mounted ME909s devuce

BAEPMOD-COM-019-A01

MU709S2 family is high-quality designed HSPA+ module in small size and Huawei standard LGA form factor which specially for industrial-grade M2M applications such as vehicle telematics, tracking, mobile payment, industrial router, safety monitor and industrial PDAs.

Based on Huawei standard LGA technology, the M709S2 modules provide a smoothly path to Huawei LTE high-speed modules.

MU709S2 family supports 21.6Mbps downlink data rate, providing data and voice service under global GSM/GPRS/EDGE/WCDMA/HSDPA/HSUPA/HSPA+ networks. The module also include enhanced features like embedded TCP/IP stack, SMTP, FOTA, Jamming Detection, Netscan, CMUX, SSL, eCall, Huawei enhanced AT commands, cell lock, network monitoring, DTMF decoder, baud rate adaptation, multi PDP, SIM swap, .etc.

ME909s-120 is the first LTE cat4 module based on Hi-Silicon chipset. Which is high-quality designed LTE module in small size and Huawei standard LGA form factor, especially for industrial-grade M2M applications such as vehicle telematics, tracking, mobile payment, industrial router, safety monitor and industrial PDAs.

  • ME909s-120 supports 150Mbps downlink data rate, including enhanced features like FOTA, USSD and Huawei enhanced AT commands.
  • ME909s-120(B1/B2/B3/B4/B5/B7/B8/B20) supports EMEA region, and has two different form factor: LGA and Mini PCIe form factor.

With Huawei pin-to-pin form factor, it is easy to migrate from MU609, MU709 or ME909u family to ME909s-120. All Huawei modules comply with the RoHS directive and Regional certification.

Features:

  • Bands: LTE (FDD): B1,B2,B3,B4,B5,B7,B8,B20; DC-HSPA+/HSPA+/HSPA/UMTS : B1,B2,B5,B8; EDGE/GPRS/GSM: 850/900/1800/1900 MHz
  • Data Transfer Rate: DC-HSPA+ :Downlink:42 Mbps, Uplink: 5.76 Mbps; LTE FDD: Downlink:150 Mbps, Uplink: 50 Mbps @Bandwidth 20M (CAT4)
  • Interface:
    • Antenna interface
    • 145 pins LGA interface
    • UART
    • PCM Voice
    • SIM Card
    • LED
  • Power supply: 3.3 V

Developement tools

The ME909s and MU709S2 uart interface can be implemented with the Empire board, follow instruction inside Quick start guide

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
_images/board_709_antenna.jpg
  1. Insert your SIM card in the slot located in the bottom layer of the PMOD-Huawei
  • Open the slot:
_images/pmod-sim-void.jpg
  • Insert the SIM in the correct way:
_images/pmod-sim-open.jpg
  • Close the slot:
_images/pmod-sim-close.jpg
  1. Insert the jumper from PIN2 and PIN3 of the SW1
_images/board_709_jumper.jpg
  1. Connect board with PMOD interface TYPE 4 to CN6 connector
_images/pmod_type4.jpg _images/board_709_cn6.jpg

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

  1. 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
  1. 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)
_images/board_709_led1.jpg
  1. 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
  2. If all works correctly sending the command AT the PMOD will reply with OK
  3. Write this command followed by enter:

AT+CGDCONT=1,”IP”,”YOUR APN”

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

  1. Launch this AT command ATDT*99# then exit from minicom
  2. 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
  1. 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.

Hardware Guide

The board is provided with:

  • PMOD-Huawei
Configuration MU709S2

The MU709S2 works with auto-baudrate or baudrate fixed: - auto-baudrate: the first time you sent a data to the device, it will set its baudrate as yours. - The device starts with a fixed baudrate and it sends data about its configuration

We have configurated the device with baudrate fixed in this way:

  1. Connect the board with the PC via USB
  2. Launch minicom and set the baudrate to 9600
  3. Send a charachter
  4. Send the command: AT+IPR=115200
  5. Turn off the module and set the minicom to 115200, then turn on the module
  6. Set these commands to configure the LED timing:

AT^LEDCTRL=2,00000FF0,1,20,2 AT^LEDCTRL=2,0000000F,1,2,20

Useful general AT Commands
  • AT+GMR: permits to know the firmware version. Actually the version is 11.652.65.00.00
  • AT+CPIN?: if MU709S2/ME909S replies with READY, the SIM (or the eUICC) is correctly seen
  • AT+CSQ: it is used to check the quality of the signal:
<rssi> GSM or UTRAN Cell Signal Strength
0 ≤ –113 dBm
WCDMA 1 –111 dBm
2 –30 –109 dBm to –53 dBm
31 ≥ –51 dBm
99 Unknown or undetectable
