Ardunio IDE does not see ESP32 Thing board

Development Boards Arduino
1

Hello,

I’ve just bought an ESP32 Thing from Sparkfun, installed Arduino IDE 1.8.5 on Windows 7 Pro, 64-bit.

I’ve followed the steps at this link- without any problems.

https://learn.sparkfun.com/tutorials/es … mple-blink

However, when I get to the “Select the Board and Port” section, the Arduino IDE does

not show the BOARD: ESP32 Dev Module.

The USB driver installed correctly, as a new COM port now shows up, and the IDE

does see the COM port.

I’ve installed the esp32 files in both the C:/Program Files (x86)/Arduino/hardware and

the sketchbook directories. Neither location is correct.

Is the tutorial out of date or did I do something wrong?

thanks

you need to include the board with the board manager in the IDE. Described at https://learn.sparkfun.com/tutorials/es … duino-core

Thanks,

but these are the same steps that I’ve already done.

Just for the fun it, I have installed the IDE (1.8.5) on windows10 and followed the steps from Sparkfun, it works but not in one go…

In C:\Users\paulvha\Documents\Arduino create a directory hardware

cd hardware

create a directory expressif

cd expressif

I downloaded the zip file from the link on the Sparkfun page and extracted the zip

renamed the directory to ’ esp32’ (full path is now C:\Users\paulvha\Documents\Arduino \hardware\expressif\esp32)

started Arduino

Found the board ‘ESPea32’ by scrolling down in the board selection (tools / board) and selected it.

In my case it then complained about BLE illegal library. That is because the directory was empty. I copied the content from GitHub and restarted Arduino. All is well. BUT it is better to download the content from GitHub as zip-file as that is more up to date.

paulvha:
renamed the directory to ’ esp32’ (full path is now C:\Users\paulvha\Documents\Arduino \hardware\expressif\esp32)

I didn't need to rename the directory, it was already that way.

However, under esp32 there is a directory called arduino-esp32

which is the git repo where all of the files are.

I’ve moved all of the files from the arduino-esp32 directory up one level,

and the IDE now sees the files.

However, this is displayed in the IDE

“Invalid library found in C:\Program Files (x86)\Arduino\hardware\espressif\esp32\libraries\BLE: C:\Program Files (x86)\Arduino\hardware\espressif\esp32\libraries\BLE”

Ok, I’m able to compile and download the Blink Sketch, but still get the error messages in the BLE directory. I’ll just ignore them.

I’m curious- this board is much faster (and more powerful) than the 16MHZ Arduino Uno that I used a few years ago, but it takes 5 times as long to compile Blink and download it

to the board.

Is this normal?

Thanks for your help? I"m not sure why the files I pulled from github weren’t seen by the IDE

so you got the same error as I did. I went to github, libraries, BLE and downloaded that content as zip. Which I then downloaded, unzipped and paste to the empty BLE directory in my hard drive. That solved the error message. Don’t know about compiling speed. I do not have that board.
