CC3235MODSF: How to reach max throughput in TCP mode.

Hosein Mobark

Part Number: CC3235MODSF


Hi,

I want to send a sensor's data by SPI to the launchpad, and send the data through Wi-Fi.

It is written in the datasheet that maximum throughput for this module in TCP mode is 13Mbps. How can I reach this rate? Is there any document or example that can help me?

Thanks,

Hosein

    The 13Mbps can be reached in a controlled environment (in an RF chamber) sending data to a local server.

    An open air with an interference on the channel (or anywhere between the client to the server) will decrease the possible bandwidth (which will cause retransmission in 802.11 or TCP level).

    In addition, sending small chunks of data (e.g. sending couple of bytes at a time) may reduce the efficiency over the air (i.e. packets will be sent with less MTU length) which will impact the possible throughput.

    Hi Kobi,

    Thanks for your answer.

    I want to send a sensor's data by SPI to the launchpad, and send the data through Wi-Fi. I have not sufficient experience in this subject. Hence, Is there any example or any document which can help me doing this project?

    Hi,

    The SDK contains various examples that demonstarte the use of SPI (master and slave - see under examples/.../drivers) as well as data sending with different protocols over Wi-Fi (MQTT, HTTP, TCP Socket - see under examples/.../demos).

    you may also check the reference design in Supporting software.

    These examples demonstrate how to access the sensors and how to connect to different cloud vendor.
