CC3135MOD: Serial Wi-Fi example

Part Number: CC3135MOD
Other Parts Discussed in Thread: CC3135

Hi all,

I have some questions about the serial Wi-Fi example mentioned here:

  • Is this example still available? I could not find it in simplelink_cc32xx_sdk_3_30_01_02.
  • Could it run on CC3135 instead of CC3235 in hostless mode?
  • Which latency does it achieve? The use case is to transfer small payloads of less than 50 bytes.

Thank you.


Best regards,
François.

    Hi François,

    The serial wifi example has largely been replaced by the AT commands example. Both of examples will allow you to connect an external device/MCU to the CC3235 over UART and use AT commands, removing the need to port the Wi-Fi host driver.

    The AT commands example will not run on the CC3135. The CC3135 is a Wi-Fi network processor only device, and will need another MCU running the Wi-Fi host driver for operation. If you have an external MCU running the host driver port, then the additional serial interface layer is redundant.

    In terms of latency, it shouldn't be that much more than if you were using the native host driver. The main additional overhead would be receiving and then parsing the serial commands. The AT command library is however not fully characterized for latency and as such there isn't a hard number for the expected latency when using the AT command example.

    Let me know if you need more clarification on the info above or if you have further questions on the CC3135.

    Regards,

    Michael
