Assistance with Electronic Device

I am embedded system electronics engineer and have been working on iot projects using BLE and WiFi communication techniques in wearable devices with smartphone, etc. Please consider sending me a message so that we can discuss further

Hi there, I have built a couple wearable projects like wristbands with lsm303c gps power regulator nrf514822. example ,goqii, xiomi fitness band, children's watch.

Hi, I would like to offer you my expertise in analog digital electronics, hardware and PCB design. And also in embedded firmware and software development. Although I haven't done any project with sim7000 in particular, but I have experience with variety of different gsm modules including SIM. Also I have done many projects which include gps, gsm and ble some of which were also in the domain of wearable devices with low power consumption. I would like to know more about your project, feel free to contact me over chat. thanks, Vladimir.

I can do your job.

Hi. I am a research and electronic engineer working on biomedical devices. I can assist you in iot based devices especially BLE, GSM and wearable communication protocols. Can also work on GPS but havnt used on it before for indoor sensing.

A proposal has not yet been provided

I can do both hardware and firmware design. I have used Eagle - KiCad and OrCAD design suits. Have experience with TI CC series bluetooth modules. Haven't designed with SIM7000 though. Which cad tool have you used up to now? What functions do you need for the design?

We are a team of engineers having expertise on embedded domain. We have worked on several embedded linux/android SBC like Wandboard(IMX6Q), AM335x-sk, Dragon Board (Qualcomm), Pi2&Pi3, Beagle Bone Black, C.H.I.P, Orange-Pi-Zero etc as well as Microcontroller Development Boards like Arduino, PIC and STM32 we have worked with various build system including make, busybox, buildroot, yocto, openwrt, android etc. BLE, IOT and Wireless Technologies: 6LBR, contiki, openthread on CC26XX platform, TI-BLE stack(v2.20) TI-sensortag CC2650 (with debug_dev_pack and lcd_dev pack),TI-Launchpad, Keyfob(CC2541) and CC2540, CC-Debugger, NodeMCU(ESP8266) we have developed GPS tracking system using SIM908MODEM and push the data to webserver along with device id, timestamp. As a part of this project, we have to create a HTTP connection with remote server and push the GPS co-ordinate for every second. So Activate GPRS connection using APN and create HTTP connection with Static IP. We have customized SIM908 firmware using EmbeddedAT interface provided by SIMCOM, so it reduces cost of external MCU to get the data from SIM908 Modems. Please check our profile for more information.

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.
