How to use

Hardware configuration

1.SIM card connection
2.Hardware connection
3.Devices Manager
4.Power on

This module comes with power adapter, micro USB cable, GSM antenna, GPS antenna and Bluetooth antenna. Besides these you should prepare two more things:

  • A SIM card, the card should be usable and GPRS access (for testing the GPRS)
  • An earphone with a microphone on it (For testing Call function)
  1. Insert the SIM card to the card slot, plug the earphone and connect the GSM antenna
  2. Install CP2102 driver, plug the jumper B, and connect the USB to UART interface of GSM/GPRS/GNSS HAT to PC with a micro USB cable. Then the PWR indicator will keep bright.
  3. Open Device Manager to get the corresponding COM port number of CP2102. For example, it is COM7 as below. Users need to choose the correct port according to the Manager.
  4. Press the PWRKEY button and hold for 1s, the NET indicator will blink as below. Generally, the NET indicator will fast flash firstly (1 time per second), which means that the module has not logged in the Network. After logging in, the indicator become to flash slowly (1 time every three seconds). Up to the local GSM network, this process that logging in will last several seconds to dozens of seconds.
    If you take too much time to log in and failed, please check that whether the GSM antenna is connected correctly, and whether the SIM card is usable and insert correctly.

Local virtual severs settings

Virtual servers define the mapping between service ports of WAN and web servers of LAN. All requests from Internet to service ports of WAN will be redirected to the computer (web servers of LAN) specified by the server IP. (see your router’s guide manual)

  1. Log in Management Console of your router with browser (read your router’s guide manual for specific address)
  2. Set Port:5000 (The Port can’t be conflict to other’s. Here we set 5000)
  3. Set LAN IP address of your computer (you can run CMD on your computer, and execute command ipconfig to enquiry the address of IPv4), 192.168.1.14 as examples
GSM-GPRS-GNSS-UM-14.jpg

Searching WAN IP

You can search “IP” on browser to get your WAN IP address, as below:

GSM-GPRS-GNSS-UM-15.jpg

GPRS Setting

  1. AT+CSQ To enquiry the quality of signal. The first parameter of response is signal quality (Max is 31). The signal stronger, the value bigger.
  2. AT+CREG? Check Network registration. If the second parameter of response is 1 or 5, it means that Network has been registered successfully
  3. AT+CGATT? Check the state of GPRS attachment
  4. AT+CSTT="CMNET" Set the Network according to actual situation. Here we use CMNET
  5. AT+CIICR Bring up wireless connection with GPRS

For more details of AT commands, please refer to:SIM800 Series _Bluetooth _Application Note_V1.04

Bluetooth Setting

  1. Connecting the Bluetooth antenna to the GSM/GPRS/GNSS HAT. Open the Bluetooth of your telephone, and make it visible to all nearby Bluetooth.
  2. AT+BTPOWER=1, Turn on Bluetooth
  3. AT+BTHOST? Enquiry the name and MAC address of module, you can also use AT+BTHOST=<Name> Command to change the Bluetooth name of GSM/GPRS/GNSS HAT
  4. AT+BTSCAN=1,10 To search available nearby devices. Search time is 10s. During searching, module will print the information of available device via UART. For example, +BTSCAN: 0,2,"H60-L01",50:a7:2b:bb:a4:50,-47 “0,2” is the ID of this device, “H60-L01” is name of device, “50:a7:2b:bb:a4:50” is MAC address of device, and “-47” is the RSSI value.
  5. AT+BTPAIR=0,2 , Pair with available device proactively, the second parameter here is the ID we got at step 4 . If get the response Error, just use AT+BTUNPAIR to delete the pairing data and pair again.
  6. After sending the pair command successfully, you can see that your telephone prompt the pair request. Then you need to click Pair to accept the request, and send AT+BTPAIR on PC to confirm the pair behavior. With these, module pair with the telephone successfully. If you don’t send the AT command to confirm pairing, the telephone will prompt information that fail to pair after a while. In this case, you need to send the pair command again. You can also use the telephone to originate the pairing request, then input AT+BTPAIR=1,1 to confirm it.

Bluetooth Connecting

To test Bluetooth connection and communication with GSM/GPRS/GNSS, you can use the Bluetooth APP. Scanning the QR code below to download the APP, then you can use it’s Serial function for test. (The APP is just used for simply test)

GSM-GPRS-GNSS-UM-21.jpg


  1. Open the APP, click SCAN button on the upper right to scan the available devices. Then choose “SIM868” (“SIM868” is the Bluetooth name of GSM/GPRS/GNSS HAT) and click UART. Then you will get the information that +BTCONNECTING on the COM assistant, which means there are connecting request. If you don’t reply it for a while, the APP will prompt that connecting failed. And the Assistant software will print +BTDISCONN to prompt you connecting failed.
  2. Connecting again, send command AT+BTACPT=1 to confirm and accept Bluetooth connection. You can see that +BRCONNECT is printed on the Assistant shows that succeed SPP connection. Then you can send data to the module with the APP.
  3. While receiving the data send from the telephone, the data will be print with ID of device, the length of string and the content on the Assistant software.
  4. Send AT+BTSPPSEND command to transmit data. After getting the response >, input the content without Enter at the end. Send 1A in HEX begin to transmit the data. Then you can see that the data is received by your phone.

Using with Raspberry Pi


UART configuration of Raspberry Pi

Because UART of Raspberry Pi is used for Linux console output by default, if we want to use the UART, we need to change the settings. Executing this command to enter the configuration page :

sudo raspi-config

Choose Advanced Options -> Serial -> no, to disable Linux’s use of console UART Open /boot/config.txt file, find the below statement and uncomment it to enable the UART. You can directly append it at the end of file as well.

enable_uart=1

Then reboot.

Minicom for UART debugging on Raspberry Pi

Inserting the module to Raspberry Pi and plug the jumper B,

Install minicom,minicom is a text-based modem control and terminal emulation program for Linux:

sudo apt-get install minicom

Execute command: minicom -D /dev/ttyS0(ttyS0 is the UART of Raspberry Pi 3B)

Baud rate is 115200 by default. If you need to change the baud rate, for example 9600, you can add the parameter -b 9600.

The user UART device of Raspberry Pi 2B/Zero is ttyAMA0, and ttyS0 of Raspberry Pi 3B

Testing Bluetooth function as examples:

GSM-GPRS-GNSS-UM-23.jpg

Examples

Python examples are provided for Raspberry Pi

  • Executing sudo python call_phone.py to make a call, if you want to change the phone number on code, just need to modify the parameter W_buf_phone as below:
GSM-GPRS-GNSS-UM-24.jpg
  • Executing sudo python send_message.py to send a message.
  • Changing the number of receiver: the penultimate parameter of W_buff array.
  • Changing the content of message:The last parameter of W-buff array
GSM-GPRS-GNSS-UM-25.jpg
  • Executing sudo python gps.py to get the GPS information
