We are looking for an embedded C(99) developer who can develop a low power LoRa temperature sensor application. The application should sleep most of the time and send a temperature measurement every 5 minutes through the LoRa(WAN) radio. The LoRa firmware uses ABP for network joining and the temperature sensor that must be interfaced is the Si7051. We will provide you with a remote desktop machine with the toolchain installed, a The Things network account to receive the packets and the remote desktop machine will have the required hardware connected via an ST-Link.

Dear Sir, We are a small R & D company, based in Bulgaria, Europe. We specialize in developing Embed systems based ST(STM32),Microchip (Atmel – AVR,ARM) and TI (MSP430) MCPUs and peripheries. For our mobile projects use nRF51/52xxx and CC2540/41 BLEs. We realize projects with requirements similar to yours based STM32L0,Si7005 .. See and my profile in Freelancer Our tools for develop STM32 based system are: Keil ARM. Atollic TRUEStudio for STM32. SRM32 DISCOVERY boards MikroPROG - emulator. If we receive more information about your project, we will give you a real cost and time to implement your project. Note: We based in Europe,Bulgaria - not customs problems and taxes for delivery models and samples for testing and build prototypes. Best Valeri T

Hello, I am very interested in your project. I have experiuence with low-power developing applications on a similar microcontroller - STM32L053C8T6 using Atollic and STM32Cube for code generation. One of the low-power application was where I had to read the temperature every 10 minutes using a LMT01, store it to a temporarily and then send the buffered measurements using a nRF24L01; on the receiver side, the data was saved to an SD. I have used both I2C and UART interfaces to commmunicate with various kinds of external ICs. Looking forward to hearing from you, Alexandru

I'm an italian electronic engineer with more than 14 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 (but I'm ready to swith to new frameworks). I work both single task and multi task environment (FreeRTOS). 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. I have experience in Android App d
