Dear Sir, I have SIM808 module, this is a GSM GPRS modem with GPS. The STM32 board, STM32f103, sends AT commands to it via UART. The GPS data is sent to AWS server every 30 seconds. This is similar interface to your requirements. I have the hardware so I can get started working on this project immediately. The AT commands for the SIM808 and SIM800L are similar. The same code will work on both modules. Instead of GPS data we will send the electric meter data from the ATM90E26. I am Electrical Engineer, many years of Firmware development, circuit design, PCB design experience. I have used different boards, Arduino, STM32, Raspberry PI, BeagleBone, DSP etc. I have used Altium Designer for many years, designed many PCBs, single layer, multi layers, RF circuit, Bluetooth, Wi-Fi, Microcontroller etc.… This includes schematic capture. I can perform circuit simulation and confirm functionality. The work performed is guaranteed. Please contact me and we can discuss the project. Thank you Sincerely, Jatin Mehta
