cc3220: Max throughput with Wifi and SPI

Darren Jenkins

Part Number: cc3220

Hi SimpleLink Wifi team,

For the CC3220: Which software example should a customer start with for maximum data throughput from Wifi to transfer data to another host processor?  I assume the fastest port is the SPI port in this case.

We state 16 Mbit/s for UDP and 13 Mbit/s for TCP in the datasheet, but I don't see an example in the SDK that behaves like we need. Maybe the software used for this benchmark is available.

Thanks,

Darren

    Hi Darren,

    You should be able to use the network terminal example to test the throughput:

    send [-help] [-c <server ip address>] [-u] [-p <port number>] [-nb] [-n <number of packets>]
    send [-help] [-s] [-u] [-p <port number>] [-V] [-nb] [-n <number of packets>]

    -c Run in client mode and connect to mentioned server - IP should be in '.' format for ipv4 and in ':' for ipv6
    -s Run in server mode - (Note that for client, a server ip address is required.)
    -u Use UDP rather than TCP
    -p Port number to send/receive data (Default is 5001)
    -nb Create non-blocking socket rather than blocking
    -n Number of packets to transmit (Default is 1000)
    -V Use IPv6 rather than IPv4

    Otherwise, a basic application which only sends UDP packets in a loop is straightforward
