Hello,
I see that you require PCB design and firmware for BLE based system, I have already worked on a similar project that has BLE module that scans BLE devices and transmit their data to cloud. I have completely designed and deployed this system on the field as an Employee tracking system.
I am an Electronics Engineer with extensive experience in designing hardware and firmware for microcontroller based systems. Having an experience of 4 years, I am comfortable with circuit design, interfacing different sensors and actuators, and establishing communications using adc, gpio, uart, spi, i2c peripherals. I have worked on microcontrollers such as STM32, Tiva C, nRF52840, PIC16, PIC18, PIC24, PIC32, Arduino, ESP8266, ESP32. I am also skilled in PCB design using EAGLE and Altium Designer.
I have completed five following projects from concept to production.
1: BLE IOT gateway
2: Vehicle detector
3: Parking guidance system
4: VMS controller
5: Countdown screen controller
Customer satisfaction is my top priority and for this I provide money back guarantee. I appreciate your feedback and I look forward to hear back from you.
Regards,
