Hi Chris, I have found that increasing the packet size helps, add "-s 32" and for the tx amplitude, add "--tx-amplitude=5000" to the command line for benchmark_ofdm_tx.py.
"ok:false pktno:65471 n_rcvd:1 n_rigth:0" or similar means that it thinks a packet was received but it didn't pass the crc check. the pktno when 'ok:false' should be ignored. I get these when nothing is transmitting so it's falsely triggering somewhere.
