I have seen applications where holtek 640 and 648 decoder/encoder chips have been used with some 433Mhz transmitter/receiver pairs without the need for any arduino or other MCU. The HT640 chip allows individual data lines held high or low at the transmitting end to simply serialize the data into bitstream which can then be easily recovered at the receiving end with a 648 chip. But I really need the higher 2.4Ghz frequencies, because my application won't have room for an antenna. The 2.4Ghz NRF24L01 seems to be just what I'm looking for, but I can't get enough information about these modules to see if a similarly simple scheme could be used. Any help appreciated\

Hi friend,

NRF24L01featuring its low-cost and long transmission distance is a good choice for the wireless transmission. Here is guide illustrates how to interface it with Arduino https://arduino-info.wikispaces.com/Nrf ... 4GHz-HowTo and an example of transmitting and receiving string http://arduino-info.wikispaces.com/nRF2 ... f-Examples
