    Important:<\/h3>\n
      \n
    1. The test code is from<\/li>\n
    2. nrf24l01 support 1mbps and 2mbps mode,<\/li>\n
    3. nrf24l01+ support 250kbps, 1mbps and 2mbps mode.<\/li>\n
    4. All example here use\u00a0nrf24l01+ in 250kbps mode.<\/li>\n
    5. PA+SMA module can further extend range.<\/li>\n<\/ol>\n

      Simplified Code:<\/h3>\n

      Tutorial and test code is originally from this youtube tutorial:\u00a0https:\/\/www.youtube.com\/watch?v=57pdX6b0sfw<\/p>\n

      My modified version of code :https:\/\/1drv.ms\/u\/s!AoQec3B3H5PMvgPwxzj8DEyq2WwX<\/p>\n

      Test Result:<\/h3>\n

      unmodified version of\u00a0nrf24l01 will able to cover a 2500 sqft house. But with simply add two antenna, it became possible. Detail can found at here:\u00a0http:\/\/www.instructables.com\/id\/Enhanced-NRF24L01\/<\/p>\n
