Hi Talents, We are trying to synchronize multiple USRP2s for MIMO transmision. Common 10MHz clock and 1PPS are used, as well as sync_to_pps() and config_mimo(usrp2.MC_WE_LOCK_TO_SMA). We tried to set the metadata of packets in order to specify a starting point of transmssion.
usrp2::tx_metadata md; md.timestamp = 99999999; md.start_of_burst = 1; md.send_now = 0; But it just doesn't work? If it is possible to synchronize the transmission, could you tell us how? Bests, Hanwen
