I am using simcom sim900A module to make call to a phone number.Making a call is not a problem.I am struggling with playing an audio while the call is attended at the other end.I am using APR33A3 in which i have recorded the audio.I don't know which command must be used for playing the audio when the call is attended. The connection (...)
I have a circuit where I am using a SIM900 gsm/GPRS module. As per the datasheet it needs 3.4 V - 4.8 V and upto 2 A of current. I am using LM2576. The input to the regulator is 12 V & 4.2 A and output (which is going to SIM900) is 4.175 V. I have connected leds for NETLIGHT and STATUS LIGHT. I have connected a switch between PWRKEY and GND (...)
HI all, I am working on a project where i have to interface gsm 800 for sending and receiving messages which works on 5v. i am searching for the gsm module with my specification, but its not available in the market. so planning to design my own. my specification is to only send any receive messages using TTL ouptuts, and (...)
Hello, I am building a battery powered application using one cell LIPO battery which is 2500mAh, I am using a system on chip for gsm and BLE, GPS module, MCU IC, some sensors. I want to know what's the best design tips to power this application from battery please? is it good to power every module/Chip using a separate (...)

Hi All. I am looking for a suitable way for making gsm/CDMA based WiFi Router. The Device will make the WiFi Shop from gsm/CDMA GPRS. I used many Wireless modules like SIMCOM or Quectel. But is there any suitable module which have in-built option to make WiFi Hot Spot? Or whats the best way to achieve (...)
I have a Telit GL865 gsm/GPRS module which is connected to a Single Board Computer (running ARCH Linux.) via Serial Port. I have implemented For GPRS connection, PPP connection as indicaten on this page: I can read Cell Tower Signal Strength Level by the following AT Command: AT+CSQ? But
hello i am balvendra choudhary i made a gsm based project in which i used atmega32 A and gsm sim900. in which response of AT command is OK. when i calling it shows RING on display. during calling the status would be three but its not what is the problem. same code is working with sim300 what is the problem i am writing (...)
I am working on some sort of security system project. I need a gsm modem for the purpose of sending/receiving text messages. I haven't used any gsm modem yet so i don't know which one should i pick. Surfing the web gives me some models like SIM900/SIM900A/SIM900D & SIM-MINI. But i don't know whats the difference in them & (...)
Hello, I am working on a circuit in which the GND ping of gsm module connects electrically to phase line of 220V AC power line ! the power supply of the circuit is supplied by a SMPS, but the connection of gnd to phase line is done because i am measuring the phase line current through a shunt resistor. now, does it make any problem (...)

hi actually i am doing a project in which when an obstacle comes in between infra red rays it should activate a micro controller. the micro controller in turn activates a video camera and a gsm module. the camera takes a video for 10 seconds and the gsm module needs to send this 10 sec video clip to 3 mobile (...)
As i am using Sierra Wireless gsm GPS module HL-6528-G2.8V, in which my module is taking GPS frames and after filling it in my packet format ,it is sending this packet format on TCP towards server. I am using TCP connect, Packet send, TCP disconnect in this fashion cycle continuous with interval of 1 minute. Problem is (...)

Hi friends, i'm doing a project is used to control our pump motors which is used for agriculture, i completed everything in my project. small intro about my project: It's fully gsm based pump control, i'm using sim900a module , pic18f4520 controller, ds1307,etc power supply details. transformer 240v/12v-2A (...)
Hello guys, I am currently making a design including a gsm module which has a 50 ohm impedance output for the antenna. However I am interested in using a dipole (73 Ohm img 43Ohm) antenna with this module. I have been searching around for either a dedicated , or discrete balun that can handle this transformation, with no (...)
Hi, We made a voice call using gsm module. But while playing voice which is stoed in apr33a3 module using gsm module, we are receiving a call itself.. can anyone give suggestion?
which controller you have used for your project?What is you application or project details?Provide information so we can help you better.
first u study what to send and recieve from gsm module.which gsm module are you using?? PRODUCT NAME : gsm MODEM HARDWARE : SIM 300 module COMMUNICATION : RS232 COMMANDS : AT INPUT VOLTAGE : 12VDC / 1AMP (...)
For this I would suggest to use PPPD or WDIAL, which makes your work very simple.
