Hello,
I know that Bluetooth uses spreadspectrum techniques, hopping from
frequency to frequency 1600 times a second. For most of the world there
are a total of 79 frequencies used in hopping except for government
regulation reasons in France, Japan and Spain only 23 frequencies are used.

Does anyone know whether these 23 frequencies are the same for these
three countries?

Thanks,
Paul

Yes.

BT supports two 'sets' of channels in the 2402-2480MHz range. The full
bluetooth range is 79 channels, the other is a subset of 23 of these
channels.
