Re: ESPAsyncWebServer Fails When Serving Large Files

I had a similar problem, I was using ESPAsyncWebServer and have a web page that draws graphs and has buttons that allow a user to download raw data in the form of large (up to 1 MB) text files. When I first tried implementing the server only about 98% of a text files would make it to the client. I f...

ESP32 External 32 KHz External Crystal How to Enable it

I have a "Sparkfun ESP32 Thing" and a "Adafruit ESP32 Huzza" both have a external 32 KHz crystal available and I am using Arduino IDE for programming. To see if the external crystal is enabled I checked the "sdkconfig" file and it shows the following. CONFIG_ESP32_RTC_CLOCK_SOURCE_INTERNAL_RC=y CONF...

Re: Measured RSSI Does Not Change

Another update from previous post.... Did another experiment using two different ESP32's each connected to their own display screen. Code was written to display the RSSI in a graph. Code in both was the same except for the differences in writing to the displays because two different different displa...

Re: Measured RSSI Does Not Change

Since my previous post did some more experimenting.... The next day after the original post the freezing RSSI was much more consistent and would last for 5 to 15 minutes and then would update as expected for a short time (5 to 20 seconds) before freezing again, this pattern lasted throughout the day...

Measured RSSI Does Not Change

Using Arduino IDE and Adafruit HUZZAH32-ESP32 Feather Board connected to a battery I wrote code to do the following. 1. ESP32 connects to WiFi network. 2. Once connected it stays in a loop and measures RSSI and displays the results to a LCD graph. The idea of the code is to be able to walk around an...
