Hi, If you ask me about my STM32 experience, I have use it since 2012 and it's a daily project for me. I'm familiar with both hardware and firmware part. I'm familiar with most of it's peripheral like Interrupt, ADC,DAC,Timer, DMA,I2C,SPI,UART, FSMC, and many more. I have used STM32 for various kind of project for Hobbyist, Robotic, Industrial, and Military application. I generate base project using STM32CUBEMX, system workbench as IDE, and gcc-Arm-none-eabi as compiller. Let's discuss about the detail of this project over messenger. Let me know your requirements, goal, and hardware you want to use for this project including wiring diagram. Best Regards, Rijal

I have extensive skills in STM32F4 and its predecessors as well as in Quectel products. I do have very good contact with Quectel's tech team as I did few jobs using their products. I use FreeRTOS mostly and GCC as development tool. Which module have you used from Quectel ? Is it EC25 ? I am flexible with my time and can work as per your requirement. I love to work in long term so if you are looking for someone who will assist till the product is launched, then I would be happy to share my skills. I have over 35+ years of skills (I am 44 years old) in electronics and 20+ years in programming. I did my engineering in Electronics and Telecommunications. Please get in touch to discuss more and know more about my skills. Thanks for your time and I look forward to hear from you. Kind Regards... Roy

Hello, We are a 14 year old Electronics design and Manufacturing Company working as an IOT design partner for Toshiba Semiconductors, Avnet, WPG and many others. We had worked for 4 years as a design house for ST micro and have also worked closely with simcom Shanghai team. we halve all relevant experience needed. have worked on stm32f030/042/051/101/103/107/207/405 stm8 Our past product experiences includes: - Communication products on (Bluetooth, wifi, gsm-2g/3g/4g with and without gps, Lora, sigfox) - commercial products (fully automatic top loading washing machine with fuzzy logic, smart microwave over, BLDC fans and compressor drives for air conditioners, Led lightings-home downlights, smart bulbs and tubelights, solar street lights and high bay lights) - Automotive products (tire pressure management systems, obd2, Bluetooth for infotainment, ev charging stations, BLDC drives, Battery management systems) - Retail automation (POS terminals and thermal printers) - Utilities (water flow meters and Energy Meters) We have a team of 40+ engineers in product design working in following domains: - Electronics hardware design - embedded software design on STM32/STM8/Toshiba TMpm series/MSP430/PIC 16 & 18/ Renessas RL78/atmega 16 and 32 series - Mechanical design on Autocad/catia/solidworks/ design pro. - Mechanical prototyping on 3d scanners and 3d printers - Application software developers on java / python / php / odoo-erp and android studio. We follow the agile work procedures with 15 day sprints and burn down charts communicated to the customers as well if needed. We have a production capacity to support international quality standards of production and packaging at a rate cheaper than china as we function in a tire 3 city of India. We can hence support mass production as well. We can also support with onsite training and support if and whenever needed. We hence requestfully submit our proposal for your evaluation and reassure you of our quality and promptness. We also are willing to sign a long term freelancer support contract for your future needs as well. We welcome your request of a NDA which we have signed for almost all of our customers before as well. Lastly, the rates can be negotiated further a bit after communications start and we understand the project a little better. Thanks & Regards, Mihir Patel
