Hello.
I am a senior microcontroller firmware developer and electronic engineer.
I have plenty of experiences in WiFi and BLE development.
I have developed the wifi and BLE communication app between the Arduino PIC18 and mobile app.
I can write the firmware based on Arduino, PIC16, PIC18 and DSPIC.
As I am an Electrical Engineer, I can design the circuits by the ARES, EASYEDA, .
Due to my experience in firmware development, I will bring you the perfect result in time with high quality. I hope we can discuss more details via a private chatting.
I look forward to your response
