20.8.2 USB Product IDs
enum hackrf_usb_board_id {
USB_BOARD_ID_JAWBREAKER = 0x604B,
USB_BOARD_ID_HACKRF_ONE = 0x6089,
USB_BOARD_ID_RAD1O = 0xCC15,
USB_BOARD_ID_INVALID = 0xFFFF,
};
20.8.3 Transceiver Mode
HackRF can operate in three main transceiver modes, Receive, Transmit and Signal Source. There is also a CPLD
update mode which is used to write firmware images to the CPLD.
The transceiver mode can be changed with hackrf_set_transceiver_mode with the value parameter set to one of
the following:
enum transceiver_mode_t {
TRANSCEIVER_MODE_OFF = 0,
TRANSCEIVER_MODE_RX = 1,
TRANSCEIVER_MODE_TX = 2,
TRANSCEIVER_MODE_SS = 3,
TRANSCEIVER_MODE_CPLD_UPDATE = 4
};
Receive mode (TRANSCEIVER_MODE_RX) is used to stream samples from the radio to the host system. Use
hackrf_set_freq to set the center frequency of receiver and hackrf_set_sample_rate to set the sample rate
(effective bandwidth).
Transmit mode (TRANSCEIVER_MODE_TX) is used to stream samples from the host to the radio.
See hackrf_transfer for an example of setting transmit and receive mode and transferring data over USB.
