I saw in the nRF24L01 Datasheet Page 23 that the nRF24L01 can operate on frequencies from 2.400GHz to 2.525GHz (125 channels). The RF channel frequency is set by the RF_CH register according to the following formula: F0= 2400 + RF_CH [MHz] e.g. channel 107 at 2.507GHz.
WLAN (IEEE 802.11b/g/n-2.4) use the radio spectrum 2.4–2.4835 GHz and Bluetooth operates in the same range.
So my guess is that CF RF channels grater than 100 are better because less interference with WLAN and BT!?
Can anyone confirm this?
What is the right RF channel?!
Re: What is the right RF channel?!
Well, it depends if you wan't to follow your nations regulations or not 
You will hovever have very little chance of other ratio interference above channel 100.
