I can use the AT command set.
I also judge all communication protocols. I realize projects related to the following written protocols. I did a remote-controlled greenhouse applications with GSM.
I perform vehicle tracking and M2M applications.
I'm experienced embedded software design with 16/32 bit processors in the C language application development.
Microchip's 16-bit STM32 series processors and sersu I use ARM processors.
Wireless and wired communications ((I2C, UART, USB, SPI), (Modbus, Ethernet, Wi-Fi, BLA, GSM, GPS, GPRS, RF)) and knowledge of the hardware and software design issues I'm experienced. I made electric vehicle production feasibility study.
I use as a professional PCB programs smoothly. I'm experienced in the appropriate PCB circuit design for EMI and EMC characteristics.
