Hi, I have experience for 15+ years in electronics/embedded development. I have several years of advanced AVR/arduino development, including library development from scratch. Practically all Arduino AVR boards used, like: 2009, 2010, UNO, MEGA, NANO, MICRO, MINI, etc. Several shields used like Ethernet (W5100, ENC28J60, etc.) with various IP protocols implementation, various graphical TFTs with and without touchscreen and various BUS types (parallel, SPI, I2C, etc.), all kinds of sensors and buses, serial and parallel memories, etc. I have extensively worked with nRF24L01+ modules and can easily make your code compile, and do whatever you want, like sending whatever data type or types you want, including data structures of several data types combined. If you are interested in my bid, please let me know some more details about your project and I'll be able to answer you back telling if I'm up to the task or not. Feel free to contact me. Regards, Carlos.
