We have designed a board with a STM32F100 embedded processor. I have a starter project for ST32 Ardunio framework, that tests all of the io's on our board and communicates with the SIM800 The project must be eclipsed based using the Slober Elipse IDE for the STM32 Microcontroller. You need to use the tasker library, the TinyGSM library and the command parser to receive SMS's and incoming calls to cause an action like toggling an IO. Our board has a SIM800, 2 relay outputs, some digital IO's The ardunio TinyGSM library does not currently support incoming SMS's or incoming calls. You will need to modify the TinyGSM library to monitor the SIM800 for unsolicited responses when a SMS is recieved or a incoming call is received. The SMS received will be parsed by command parser library and a callback function will action the required. The changes made to the TinyGSM will be released We already have a Atmel based version of this board and this is the designed replacement. The selected freelancer will be supplied with a existing user manual detailing the commands and a schematic of the board and the sample project. I am an embedded engineer but don't have the capacity at the moment to complete the project. I would like to work with an individual engineer and there is the possibility of long term relationship going forward as we have many developments in progress. The final project will be released as open source.

Hello, I'm interested in your project. I have a couple of questions though: Do you have a full spec of the commands you need to parse? Could you send me a link to take a look? What other functions or tasks does the board need to perform? I can prepare a demo if you want. I look forward to your reply. Thanks. Edit #1: I forked the TinyGSM library and added a couple of functions to detect incoming SMS and to read them. If you wish you can check it out here: [login to view URL] (examples/IncomingSMS). Thanks.

Hi Sir, We have used the STM32 BOARDs before and we have them in our inventory. Plus we are good in dealing with this tiny gsm library famous for decoding NIMA0183 protocol of GNSS. Lets talk to us and we will do this project for you. we have also GPS receiver present in our inventory that is SIM68 so we can also use it to demonstrate the project for you. We are professional engineers and developers who do such projects from the last eight years. We offer you our skills for this project at very low rates comparatively without compromising the quality of work. Let me introduce you to our company TURKTRONICS. We are TURKTRONICS. We are professionals with 8+ years of experience in Circuit designs, PCB designs, embedded system solutions, mobile app development, programming and software development. We provide complete end to end solutions for all kind of development projects. IOT is our strong point. In this bid, prototyping and shipping cost is not included however paying extra slight of money to include prototypes. We have collaboration with Atechcircuits & WELLS Inc in Shenzhen China for excillent quality PCB manufacturing. We care about our clients and help them to get out of any potential problem throughout the projects and also give post completion technical support if ever required. We are very much looking forward to hear from you on this in coming days! Cheers!!! Ahmad Lead Technical Engineer TURKTRONICS An Internet of Things Company !

i have great experience in dealing with ST products. i had already used STM32f103 in many projects. also for the GSM module i have used SIMCOM 900, 800,800c,5320. i faced a lot of problems because of the messages and calls but i overcome all of that. also i mainly uses c and c++ in programming. if you are intersted we can have a discussion. thanks for reading my proposal

I'm an italian electronic engineer with more than 15 years of work experience. I work as HW designer; FW and SW developer. As HW designer, I work in Altium, KiCad and Orcad and I have experience in development single MCU (Microchip PIC and ARM Cortex) boards with several digital I/O (GPIO, UART, SPI, I2C, PWM,....) and some analog I/O. I design complete board: power section, MCU section, peripheral section,.... I design also boards with battery power; so I have experience in low power PCB design. I have also experience in commercial boards (Arduino, Raspberry, Beaglebone,...) shields design. I have also experience in bluetooth (both 2.0 and 4.0) PCB design. As FW developer, usually I work in C for Microchip PIC (MPLAB X + XC compilers) and Eclipse + GNU ARM for different ARM Cortex M3/M4 manufacturers (STM32Fx, NXP, EFM32 SiLabs, but I'm ready to learn new frameworks). I work both single task and multi task environment (FreeRTOS and RTX). I write code both for low level driver (GPIO, UART, SPI, I2C, PWM....) management and for high level/final application. I work also in "C code" commercial boards Arduino/ESP8266 and Linux embedded commercial boards (Raspberry and Beaglebone). I have also experience in bluetooth (both 2.0 and 4.0) programming. As SW developer, I work in C, C++, .NET, Java, and lot of others programming languages. Mainly I work for Windows O.S., but I have experience in Linux development too. I have experience in openCV library for image/video processing.
