Gazell Availabel Channels

[Rick.Soza]

What are the allowed channel numbers for gazell?

In the gazell user manual it states, a possible 80 channels. While the nrf_gzll_set_channel_table () API reference says channels can be "0 <= channel <= 125, where the actual centre frequency is (2400 + channel)*".

But the ISM band only operates from 2.4GHz to 2.5GHz, so 2525 would be outside the band.

So are channels 0 to 100 only allowed?

Hi

If I am not mistaken the ISM band covers the range from 2400-2483.5MHz.

Technically that means channels 0-83 are safe to use, but it is good practice not to use the lower and upper channels as you could get outside the band when you factor in the bandwidth of the signal (in particular this could be an issue when using the 2Mbps mode).

To be 100% sure that you are inside the band regardless of the bitrate I would then recommend sticking to channels 2-81.
