We are a start-up company, looking for a professional programing team to take responsibility to finalize the firnware programming side of the developed board. we have the board which has been completely assembled with the following components : The nordic nRF52840 · A switch and a RGB led (red-green-blue) · A motion sensor (accelerometer and magnetic sensor à ST LSM303C) · An AFE (TI AFE4404) and OSRAM SFH7070 (2 green leds, 1 photodiode) · A micro-USB connector to charge the battery and access the nRF52840 · A matching circuit and a Bluetooth antenna · A debug connector to program the nRF52840 · A chip responsible to charge the battery if a USB cable is plugged in (battery charger, Microchip MCP73832T) and a power management chip to transform battery voltage into 3V (Microchip MCP1810) · A flash memory of 256 MBytes, maybe the Micron MT29F2G01ABAGDWB The goal of the project is to program nordic and TI chip. TI chip is controlling the LEDs/photodiode. Nordic chip is controling the TI chip, accelerometers, recording the data on the memory and sending the informtion through bluetooth to the mobile app. The information is the collected data by photodiode with frequency of 100hz without any processing. we don't do any analysis by the nordic chip, only controlling accelerometer, TI chip, recording, saving, and sending by BLE.

Hi, I will utilize Arduino IDE to program Nordic Chip. as it's already Arduino core available for that chip. I think it will be faster development process , because I think almost all IC you used has already developed by lot of Arduino developer over there, so I will looking for available Arduino library for every sensor , and if I didn't find it I will program it by myself. and for TI AFE4404, I did a little browse about it and I found some Arduino Library for it. For faster development process, If you accept it I will requesting you to send me one complete package of your development board including sensor, So I can get in touch and program it directly. I also need an API for sending data to your APP. I have do firmware programming since 2012, and I'm familiar with most of peripheral used for sensor interface like SPI,I2C,UART, and many more. I have successfully designed lot of project from Hobbyst, Robotic, Industrial, to Military. I have bunch of experience using Arduino environment, and I know both of firmware and hardware part, becauae my background is Electronic Engineering and I have work on that Industry both as Electronic Design & firmware engineer. let me know your response about my proposal. if you ok with this we can start working soon. let's discuss the detail over chat. Best Regards, Rijal

Hi, I'm Embedded System Engineer. I have experience developing product prototyping, PCB design&layout, firmware and C/C++ applications in Windows and Linux OS. I understand your requirements, because I worked with similar projects like smart locks, key finders, beacons, wireless RGB controllers, etc., and they communicate with Android and iOS Apps. I have a lot experience working with Nordic Semiconductor Chips, so I will help you with compact code, because I will choose the better plataform for this project (Nordic SDK, mBed or Arduino), because Nordic have price variations according to RAM and Flash size, then if you want a massive product, this will be a tricky point. So I would like to work in this interesting project and share my experiences in developing product prototyping. Regards! Jhon Zumaeta

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.
