Problem solving for Serial communication b/w Gsm module and Controller

Hi I'm Matt from Warton Circuits Ltd located in the UK. I have about 20 years industry experience in microcontroller development from industrial control to home appliance firmware. I have previously worked on a project using Telit GPRS modems, sending / receiving SMS messages on an 18F PIC and designed a boot loader which would connect via GPRS to the company website, download the latest firmware to external flash and then flash the main PIC with the contents if it downloaded correctly. I feel that working in this project gives me the experience to help you with your problem - although a different micro, the AT command set of the modem will be similar. I look forward to working with you on this.

Hello We have been an engineer for more than 8 years in the market and have already developed projects for several companies using microcontrollers like PIC, AVR, Arduino, ARM, NXP, Nordic, Texas among others. Using the general description of your project is possible to make a generic estimate, but the refinement of the total amount of work and the value of it will depend very much on the quantity and complexity of the features to be implemented, so I look forward to your contact for more details. Thank you.

I am a 4th year Electronics Engineering student. I have worked on many projects in the past using arduino. I am familiar with the concept of data transmitting and receiving using GSM module. I can finish the project in 1 to 2 days.

hello sir I am expert in GSM module like - SIM900 or SIM800 series please contact for more information contact - 9639835555

Hi, I have had experience with GSM modules and I'm knowledgable with STM32 programming. We can use STM32CubeMX to provide the template for TCP/IP Connection. The functions for TCP/IP can be found on the support .h header files. You just need to call the functions to send and request a connection. Hope I can help you. Best regards, Warren

Hello, I am an expert in Arduino and I faced this problem and I can fix it contact to me if you interest

I am a Electronic Component supplier , I can supply you with Integrated Circuits, Microchips , MicroControllers, Voltage Regulators, Microprocessors, Crystals, Transistors and other (LCD, Connectors, Heat Sink etc. ) Active and Passive Components. Components can be delivered any place in India.

Hello! I am embedded software engineer with more than 10 years experience. I have big experience with different GSM modules (Sierra, Cinterion, SIMcom) and with STM32 MCU (F407/F413). I wrote wireless drivers for OS FreeRTOS and telematic protocols. Please keep in mind, that I have STM32F4 Discovery kit for debugging firmware. I would like to know more detail about your project.
