Re: ESP32S3 Unable to set specific GPIO as outputs
I've forgotten to put paste under the ground pad entirely before. That is probably a bit more obvious than a couple missed pins

Re: WiFi.setAutoReconnect function
Even better, ping what you actually want to get to. Google's dns servers have pretty good uptime. The endpoint you target may not.

Re: WiFi.setAutoReconnect function
If you manually turn it off with a disconnect, it doesn't reconnect. It is equivalent to ending the session. Reconnect means that if something happens (typically the router reboots), the client will attempt to re-establish the existing session there. In practice, I find it insufficient for much the ...

Re: Seems to program but won't run code
If you are not intending to make a USB device out of the esp32, then you want hardware CDC. You also will want the ID pin on your USB port tied to ground with 5K1 (this sets USB-OTG). Try this:

Re: [ESP32 Dev Kit] ADC pin readings always HIGH with external battery connected
Does "connected to battery" mean that the battery is connected to the 5V input, so that it is going through the LDO, or directly powering the esp32 on 3V3? Not sure why it would be different battery vs usb, but 100K is a bit high for the current limiter. Try taking it down an order of magnitude (10K...

Re: Sending video(.avi) and audio (.wav) files from ESP32 via http post multipart/form-data to server
Just a couple comments to help you optimize: 1) reading/writing to sd is slow. You can optimize this by making your transfers match the sector size of the device. For sd cards, that is 512 bytes. If you set your buffer to that size, it will read a whole sector at a time, which should be a bit faster...

Re: Can ESP32-C6 use GPIO to wake up Deep Sleep?
Just an fyi here that maybe will keep someone else from wasting their time- the esp32-c6 ulp does not have access to the ADC peripheral.

Re: Read MSEGQ7 with ESP32 (Read 5v from a 3.3v input)
First, hook a multimeter up to your voltage divider and make sure it is reading in the range you want. I would actually recommend taking it down so that the very top of your range is 1V (maybe 10K and 2K7) so you can use the lowest attenuation on the ESP32, which will have the best accuracy. arduino...
