Found another FCC-approved produced that references Gazelle; a virtual treadmill: fccid.io/.../Test-Report-2963030

The Itvers ITV-R01R Touch Air Remote was granted certification by the FCC back in 2014: fccid.io/2ABLB-ITV-R01R

In the "Operational 2 FHHS" submitted document, it describes how it uses the Gazell protocol.

Did someone already achieve the FCC certification with the Gazell protocol?

The biggest problem which I see is mentioned in §15.247 -> The system shall hop to channel frequencies that are selected at the system hopping rate from a pseudo randomly ordered list of hopping frequencies. Each frequency must be used equally on the average by each transmitter

Gazell is normally using a fixed channel table. Is it somehow possible to make this table randomly generated?

Thank you for your response, I will check the radio_test_example.

There's no specific document related to Gazell, but you might have some benefit from reading the white paper on regulatory and requirements around the world.

So the two parts of the FCC standard that you would have to test towards is either 15.247 or 15.249. Depending on the bandwidth and output power used. Normally it's not a problem for our customers to meet the requirements, but we still highly recommend to follow our reference schematic and layout closely.

There might be some practical details with regard to the testing that could vary from test house to test house. So I would also suggest to contact the test house you're planning on using to hear what kind of test modes they prefer to have available. We have a radio_test_example in the SDK with functions for most normal test modes.
