"I am currently leading a team that aims to develop a universal 2.4GHz remote controller based on CC2500. The main function is to collect signals from all 2.4GHz remote controllers, demodulate the received signals, and save the decoded high and low level remote controller data to an MCU. Additionally, it should be capable of transmitting the decoded data to achieve the same functionality as native 2.4GHz remote controllers. Therefore, I have utilized the asynchronous serial port function of CC2500, setting GD0 as the data receiving port, and employed GFSK modulation to demodulate the remote controller data. Furthermore, I used the 'Gqrx' software to obtain the basic center frequency of native 2.4GHz remote controller signals, which is approximately 2402MHz, with a bandwidth greater than 1MHz. However, on page 27 of the CC2500 datasheet, it describes the maximum receive bandwidth of CC2500 as 812kHz, which is obviously less than 1MHz. This does not meet the requirements for our development goals. I would like to inquire if there are alternative chips that can meet our development needs, or if our development requirements are inherently unattainable? I would appreciate any technical advice when you have time. Thank you very much."
