Hi, For your Case, I think we can use NRF51 Microcontroller from Nordic. It's already contain Both Bluetooth and ARM Cortex M0, And we just need to add some voltage regulator, battery charger circuit if you want, and Of course Accelerometer itself. It's already support Arduino Environtment, So it will be easier to program it. But if you are not confident with having Bluetooth and Microcontroller combined in one SoC, we can use separate ARM Cortex M0 device, it can be STM32F0, or another MCU, Just discuss it. I have managed several similar project before, and I know some of its related PCB design Issue, like Antenna, Power, charging, etc. I will use Eagle to deisgn this PCB, and I think 2 layer is enough. I just need to know your dimension constraints. I have became PCB designer since 2012 and has done lot of project for various application, from hobbyst to Military based. My background is electronic engineering, so, I know how to analyze circuit refering to it's design guide. Let me know your response about my proposal. If you Ok with this then we can start this project soon. It's fairly simple project in PCB design. I will provide you manufacturer file and BOM, so you can order it to PCB manufacturer. I will recommend Chinese manufacturer for this. Best Regards, Rijal

I have long experience with 8-bit , 16-bit and 32-bit micro-controllers. I work with Microchip (PIC) , Atmel (AVR , SAM) , ST (STM) , TI (MSP) , Nordic (nRF52), and NXP (LPC) micro-controllers. I use KEIL IDE , Atmel Studio , Code Composer Studio and MPLABX IDE . I deliver tested , neat and well-commented code that can be reused or modified for future development. You can see samples of my previous work on my portfolio and youtube channel. More to be discussed once you contact me . BR, M.T.

Hello I am excited to see your proposal because the sensors you mentioned are what I have worked on before. I designed ECG recognition system and used heart rate sensor in this system. And I integrated this system with UWB indoor positioning system so the person with this system can be tracked in the indoor system. I used ARM M3 as a CPU and the sensor data is processed in the CPU. I think your system can be similar solution with my project. Should you have any question, please let me know. Best Regards, Radovan

I'm an 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.
