CTE Transmitter (cte_transmitter)

Commands and events in this class can be used to manage Constant Tone Extension (CTE) transmission.

CTE feature is only supported by specific devices. Commands from this class will return bg_err_not_supported on devices that do not support CTE.

cte_transmitter commands

cte_transmitter_clear_dtm_parameters

This command can be used to clear CTE related parameters that were previously set for LE transmitter test. Default values will be restored for these parameters.
