CC3235SF: How many maximal Wi-Fi connections can be made in parallel?

Part Number: CC3235SF
Other Parts Discussed in Thread: CC3135

Hi,

My customer requirement is using Wi-Fi device (server) as AP mode to receive up to 240 STAs (client)to get data stream like ADC sensor data,maybe 2 bytes at most,  polling rate is 1 time per second.

I think I may have these options:

1. Use C3235 server with AT command demo code to config it as AP mode, so all STAs connect to server directly.

2. Use CC3235 server with AT command to config as STA mode then all STAs connect to same AP.

3. Use CC3135 with powerful Tiva MCU as AP mode, let STAs connect to it.

With these options, is that possible to have 240 STAs to connect? If not, what is the maximal connections we can have?

Thanks a lot.

  • Hi,

    Answers to your question.

    1. This is not option for you. CC3235 device supports up to four clients at AP mode connected simultaneously. 240 connected clients is more that is commonly supported by SOHO commercial APs.

    2. This is possible. But I you will need to use AP which have capability to connect 200+ clients. Another option can be multiple APs usage.

    3. No this is not possible. CC3135 supports up to 4 clients at AP mode as well.

    It is not possible to have connected 240 clients to CC31xx/CC32xx devices. You will need to use high performance AP with capability for connect up to 250 clients (come high-end models of Cisco, Ruckus, Ubiquiti, Aruba have such capability).
