Function esp_idf_sys::ble_gap_dtm_tx_start

pub unsafe extern "C" fn ble_gap_dtm_tx_start(
    tx_chan: u8,
    test_data_len: u8,
    payload: u8,
) -> c_int

Start a test where the DUT generates reference packets at a fixed interval.

@param tx_chan Channel for sending test data, tx_channel = (Frequency -2402)/2, tx_channel range = 0x00-0x27, Frequency range = 2402 MHz to 2480 MHz.

@param test_data_len Length in bytes of payload data in each packet @param payload Packet Payload type. Valid range: 0x00 - 0x07

@return 0 on success; nonzero on failure
