Adafruit Huzzah ESP32 - Assistance in Initial Setup

by JNKR on Tue Oct 22, 2019 6:03 pm

Hello,

I am new to using Arduino and the Bluetooth device (Huzzah ESP32). I am writing to ask for help on how to setup the Huzzah ESP32. I have the FTDI Serial USB cable to connect to my laptop and I have been referencing my initial setup on the Using with Arduino IDE page (https://learn.adafruit.com/huzzah32-esp ... rduino-ide) but I get the same error message:

"Arduino: 1.8.9 (Windows Store 1.8.21.0) (Windows 10), Board: "Adafruit ESP32 Feather, 80MHz, 921600, None, Default"

Sketch uses 207705 bytes (15%) of program storage space. Maximum is 1310720 bytes.
Global variables use 15228 bytes (4%) of dynamic memory, leaving 312452 bytes for local variables. Maximum is 327680 bytes.
esptool.py v2.6
Serial port COM3
Connecting........_____....._____....._____....._____....._____....._____....._____

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences."

I have downloaded the FTDI USB Driver software, downloaded the Arduino IDE software, I am using the "Adafruit ESP32 Feather" as the Board and then I copied and pasted the LED BLINK test. I compile and upload the LED BLINK test file and that is when I get the error message that I posted early.

I would appreciate your help and guidance. Especially, since I am new at this.

Are you putting the ESP32 into bootloader mode by holding the GPIO0 button down when you click the reset button?

Yes, I hold the GPIO0 button, press and release the RESET button, and then I release the GPIO0 button. Then through Arduino IDE I select Sketch ====> Upload to upload the LED Blink Test that was recommended. Is there a header or specific code that I did not apply? And thank you for your response.

Post a photo showing your hardware and connections and we'll take a look at those. 800x600 images usually work best.

I have been trying to figure out how to post photos. Could you please inform me how this message board allows pictures? I cannot attach a photo from my computer to the message board. If I cannot upload from my computer how do I upload pictures to this message board so we can see what I have?

The forum has a 1 MB limit for picture file size. You may need to resize it so that it's smaller than the limit.

I figured out the problem with establishing communications with my Adafruit Huzzah ESP32. It is either the driver for the serial to USB communication or the Arduino IDE (still trying to narrow it down). I reinstalled the software on another computer and I was able to communicate with the Adafruit Huzzah ESP32 and executed the LED Blink test.

I appreciate the consideration and comments. On a future note, if I could get some clarity on how to upload pictures then that would be great and thank you!

You can add images to a post with the 'Choose File' and 'Add the file' buttons under the pane where you compose a message. As mentioned, the forum puts a 1MB limit on file sizes, but 800x600 images rarely come anywhere near that limit.

After you click the 'Add the file' button, you'll get a list of images associated with the post. There will be buttons that create text markers so you can place them inline, and if you don't, all of the images will default to appearing below any text you've entered. You can use the 'Preview' button to see how the post looks with images.
