Dear Sir,
I have designed our own BLE module using the nRF51822. This was designed for iBeacon functionality. The module is small and uses CR2032 battery. I have experience with GSM GPRS modems. I have a working SIM808 GSM GPRS system, which uses STM32 to send AT command to the modem. I have written code for this and created hardware PCB design.
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. I have used various IDE software, Arduino IDE, IAR workbench, Keil etc. The work performed is guaranteed. Please contact me and we can discuss the project.
There are many requirements I would like to discuss them over the phone and explain the design process and steps involved.
Thank you
Sincerely,
Jatin Mehta
