ESP32 Modulation Data Rates

Postby BrettG » Thu May 23, 2019 8:49 pm

Hi, I have been looking through some of the datasheets of the ESP32 particularly at the WiFi modulation rates and initially I found that most datasheets only claim data rates of 6 and 54 Mbps on 11g like shown below:

But recently I found the FAQ docs for ESP32 (https://www.espressif.com/sites/default ... Qs__EN.pdf) to advertise all the data rates in between 6 and 54 Mbps.

Is the ESP32 capable of using the intermediate datarates like the FAQ states? If so is it enabled by default?

Thanks,
