BLE radio channels

[Roei]

Hi,

Is there a difference when transmitting/receiving data via the different RF channels, as the frequency ia different?

Thanks!

Hi

Not quite sure what difference you are talking about?

The carrier frequency of the radio signal is different, but everything else should be the same. Packet timing, packet format etc.

What you might see in practice is that there is a higher level of packet loss on some RF channels, if there is a lot of interference from other radio sources on that particular frequency (if there is a nearby WiFi network for instance). 
This is why in a Bluetooth connection the RF channel changes for every connection event, to make sure that you don't stay on any single frequency for too long. 
There is also a feature to allow you to map out bad channels, and restrict the Bluetooth connection to those channels where you see less interference. 

Best regards
