TCPIP

TCP connection maintenance and detection

Most of the modules are connected to the Internet through GPRS gateway. GPRS gateway here has the similar functions as the router in LAN. Every time when the module tries to connect with one server in the internet, GPRS getaway should assign a port to the module. A problem will be caused when the connection between the module and the Internet is established via this port. Since the port resource of GPRS gateway is limited, so it will have some restrictions on these ports for the terminals within the GPRS network. If there is no data transmission on the TCP connection for a period of time, it will release the port to other connection to achieve a rational allocation of port resource. So the TCP connection between the module and the server may be disconnected by GPRS network without any notification.

★Jamming Detection★FOTA★DTMF Decoding & Encoding★Time Synchronization★Dual UART for customer★Text To Speech (TTS)★GSM Base Station Location Positioning

www.quectel.com

Jamming Detection

• AT+QLJDC=1 // Enable jamming detection function 1) Firstly, should enable the Jamming Detection Function .•2) After that, when there is jamming, the module will report +QLJDR: 1 automatically. •3) User can output the results through serial port by using this function when there is jamming.

Note: During the whole period of jamming, it cannot report “+QLJDR: 1” continuously. It will report “+QLJDR: 1” again until the next jamming comes

www.quectel.com

FOTA

FOTA means upgrade Firmware Over-the-Air

FOTA Process

www.quectel.com

FOTA

FOTA means upgrade Firmware Over-the-Air

FOTA updating process consists of three stages: 1) generating the update package (we will call it delta package in this document); Delta package is normally generated by device manufacturer. For Quectel module, can achieve delta package from Quectel when they need to update the firmware of Quectel module.2) delivery of the update package; A Customer needs to put the delta package on their own network server (HTTP, FTP, TCP etc), and uses GPRS function provided by Quectel module to download the delta package from their network server into the device.B. User can also copy the delta package to a USB disk, and use MCU to read it from USB disk.3) performing the update. Quectel offer 2 ways for FOTA operation, A. AT command , AT+QFUA B. Open CPU API

www.quectel.com

DTMF Decoding & Encoding

• The DTMF tones and sine tone special frequency are used widely in the applications of security monitor, wireless communication, vehicle remote control, etc.

• It is an economical solution to embed the encoding/decoding DTMF and sine tone special frequency in GSM/GPRS module

• 1. send DTMF• DTMF tones can be generated by AT+QWDTMF and directly coupled to voice uplink channel. This method doesn’t need any additional circuits.

• 2. Decode DTMF• The module will detect DTMF automatically and output the corresponding ASCII code through UART port when AT+QTONEDET=1.

www.quectel.com

Time Synchronization

There are 3 ways for Time Synchronization

1. network Date and time updateAT+QNTP=”TIME SERVER ADDRESS”Such as

AT+QNTP="210.72.145.44",123OK+QNTP: 0-----return OK ， means Synchronize local time directly. Please note that this is GMT. Time zone is 0AT+CCLK?+CCLK: "11/07/15,09:44:17+00"OK

www.quectel.com



2. Synchronize GSM network time

AT+QNITZ=1 ---should network supports

if GSM network is unavailable, AT+QNITZ will not work. For AT+QNITZ needs to synchronize the local time via GSM network.

www.quectel.com



3. Form GSM location get the time

AT+QGSMLOC=4 / get longitude, latitude time+QGSMLOC: 0,121.389018,31.168729,2011/10/26,05:49:10

Note: AT+QNTP and AT+QGSMLOC works via GPRS network.

www.quectel.com

Dual UART for customer

Quectel GSM module can offer 2 UART for user. One can focus on data transmission. And another focus on device control. Command AT+QEAUART to enable and set the configuration of the UART.

• UART for module:

• MAIN UART: AT, GPRS DATA, FAX, MUX, D/L

• UART 3: AT command

• DEBUG UART:DEBUG software ,catch log

www.quectel.com

Text To Speech (TTS)

User can input text and output speech by using this function via the auxiliary channel of the module.

• Note: TTS function is only supported by the special software version

• AT+QTTS=<mode>, <text>• Stop TTS, Parameter <text> is left out。• Start TTS, <text> is UCS2 format.• Start TTS, <text> can be input directly. .• Normal characters in ASCII format, and • Chinese characters in GBK

• Example : AT+QTTS=2, “hello thank you”

www.quectel.com

GSM Base Station Location Positioning

AT+QGSMLOC=4/get longitude,latitude time+QGSMLOC:

• 0,121.389018,31.168729,2011/10/26,05:49:10

GSM location use GPRS exchange data,So before active it ,we recommend to do some GPRS initialization

AT+QGSMLOC=1/2/4/5/8Type 1 and 2 are defined as Locating Algorithm A. Type 4, 5, and 8 are defined as Locating Algorithm B. It is strongly recommended to use Locating Algorithm B. The difference between Type 4 and 8 is that the module can collect more information from nearby GSM coverage communities to execute positioning via Type 8. When use Type 8, AT+QENG=1 must be enabled.

• Notice: we do not promote this function.

Power features of module

The power supply is one of the key issues in the designing GSM terminals. Due to the 577us radio burst emission in GSM every 4.615ms, power supply must be able to deliver high current peaks in a burst period. the max current consumption could reach to 1.6A during a transmit burst. It will cause a large voltage drop on the VBAT, it is recommended that the max voltage drop during the transmit burst does not exceed 400mV.

www.quectel.com

Note :1) Power supply rang of module: 3.3V~4.6V (Vnorm=4.0V ).2) The power supply is capable of providing the sufficient current up to 2A at least2) In order to get a stable output voltage, better to place a 5.1V zener diode close to the pins of

VBAT.3) For better power performance, it is recommended to place a 100uF tantalum capacitor and ceramic

capacitors 100nF, 33pF and 10 pF near the VBAT pin.4) The VBAT route should be wide enough no less than 2mm to ensure that there is not too much

voltage drop occurring during transmit burst and the Module’s GND trace should be as wider and shorter as possible.

SLEEP MODE

Sleep mode

The SLEEP mode is disabled in default software configuration. Customer’s applicationcan enable this mode by “AT+QSCLK=1”. When “AT+QSCLK=1” is sent to the module, customer’s application can control the module to enter or exit from the SLEEP mode through pin DTR. When DTR is set to high Level and not interrupter, the module will enter SLEEP mode automatically. In this mode,the module can still receive voice, SMS or GPRS paging from network but the UARTport is not accessible.

Wake up the module from SLEEP mode

When the module is in the SLEEP mode, the following methods can wake up the module1) If the DTR Pin is set low, it would wake up the module from the SLEEP mode. The UART port will be active within 20ms after DTR is changed to low level. 2) Receiving a voice or data call from network wakes up module.3) Receiving an SMS from network wakes up the module.

Note: DTR pin should be held low level during communication between the module and DTE. If the module does not act as 2) or 3) , few seconds later it will came into sleep mode again.

Notice for SIM interface Design

Place the SIM card holder close to module as close as possible. Ensure the trace length of SIM signals keeps less than 200mm.

1) Keep the SIM signals far away from VBAT power and RF trace.

2) The width of SIM_VDD and SIM_GND trace is not less than 0.5mm. Place a bypass capacitor close to SIM card power pin. The value of capacitor is less than 1uF.

3) To avoid possible cross-talk from the SIM_CLK signal to the SIM_DATA signal be careful that both traces are not placed closely next to each other. The traces of SIM_CLK, SIM_DATA and SIM_RST are recommended to be around with GND independently.

4) All signals of SIM interface should be protected against ESD with a TVS diode array. It is recommended to add TVS diode and The parasitic capacitance of TVS diode is less than 50pF.

5) The 22Ω resistors should be added in series between the module and the SIM card so as to suppress the EMI spurious transmission and enhance the ESD protection. All the peripheral components are recommended to place near the SIM card holder.

RF interface

www.quectel.com

1) Control corresponding W and S of 50 ohm coplanar waveguide. Keep in mind that reminding PCB manufacturers of controlling the accuracy of W and S.

2) To achieve good ground performance for RF signal, connect ground pin on either side of RF pin with main ground closely.

3) Keep out pouring copper in the surface layer of RF pin area to reduce parasitic effect. The RF trace line should be as short as possible. It will be better for RF trace line to avoid vertical angle layout.

4) Keep a certain distance between signal pad and ground when using SMA as RF connector. If the signal pad is in SMD type, keep out copper on the corresponding area under signal pad.

5)Ensure the corresponding reference ground of RF trace line is integrated and more ground via is added to help RF reflow. Guarantee the contact area that is in the same layer with RF trace is as large as enough and its corresponding reference ground in the opposite layer is as integrated as possible meanwhile ensure the two layer ground is connected by amount of ground hole.

6) Three components consist of PI type matching circuit shown as Figure 1. Place these components to antenna as closely as possible. If the distance is so short that no component can be placed, the matching circuit also can be removed,

Self-AGPS EASY Technology(1)

EASY™ is the abbreviation for Embedded Assist System for quick positioning. With EASY™ technology, the GPS engine can calculate and predict automatically single ephemeris ( up to 3 days) when the power is on, and then save the predict information onto the memory. So the GPS engine can use the information for positioning later if there are not enough information received from the satellites.

This function will be helpful for positioning and TTFF improvement under indoor or urban conditions.
