Hello,
during throughput test were expecting ~50Mbps speed for all modes, unfortunalety we have results as below:
iperf3 -c 192.168.1.123 -b 100M 33Mbps
iperf3 -c 192.168.1.123 -b 100M -w 256K 33-34Mbps
iperf3 -c 192.168.1.123 -b 100M -R 27Mbps
iperf3 -c 192.168.1.123 -u -b 100M 51Mbps
iperf3 -c 192.168.1.123 -u -b 100M -R 35-36Mbps
Only for UDP mode in, one direction we were exceeding 50 Mbps. The test has been performed with the old Linksys AP which supports 802.11n mode only. BLE was not used. No modifications in SDK were done.
We tested in normal conditions as well as in a silent RF chamber. We tested EVB also with embedded and next external antenna, without any spectacular improvements. The question is what may be the reason for that and how we can increase throughput numbers.
The test was done on your EVBs + Beagle Bone ( BEAGL-BONE-BLACK + BP-CC33-BBB-ADAPT + BP-CC3301 )
The system reports such status after connection establishment:

Thank you for help.
