I am getting the following error on upload. Would appreciate your input to resolve.

Hi.
I’ve never faced that error.
Did that happen with just that example, or it also happened with other sketches? Can you try a blink sketch and see if you get the same error?
Regards,
Sara
x3mvz5pl5g5k answered 5 years ago
It is just with this example. Blink is good. I rechecked and loaded the following sketches without issue as well:
– ExternalWakeUp_ext1_with_GPIO
– Hall_Effect_Sensor
– PIR_Interrupts_Timers
– TimerWakeUp
– Touch_Sensitive_LED
– WiFi_Web_Server_Outputs
However, I am also experiencing errors with the following sketches:
External Wake Up

I even reinstalled the Arduino IDE and the servo library, but again got these errors:

So that is a total of three sketches that I am having some frustration.

Hi Jack.
I’m sorry you’re having those troubles.
- External wake up: you’re not using the code we provide in the unit. You’ve probably modified something the wrong way. For example, the error suggests that you have a line with “void print GPIO wake up”. If you are trying to create a new function, its name shouldn’t have spaces.
- Servo: if you go to your libraries folder at C:\Users\jack\Documents\Arduino\libraries\, you should have a servo library for arduino, besides the ESP32 servo library you’ve installed. Move the arduino servo library out of that folder, and everything should work fine.
- As for the asyncrhonous web server, I don’t know what might be issue. Have you installed the libraries properly? In which folder are your libraries located?
Regards,
Sara
x3mvz5pl5g5k answered 5 years ago
I also tried to run these sketches on a different computer, but instead faced another separate problem doing this. After updating the Arduino IDE, I tried to install the esp32 board by adding the appropriate line in Preferences:
https://dl.esperssif.com/dl/package_esp32_index.json
– and then went to board manager to install the boards, but instead ended up with the following error:
Error downloading https://dl.esperssif.com/dl/package_esp32_index.json
It seems to be a week with a lot of issues for me!

x3mvz5pl5g5k answered 5 years ago
Hi Sarah Thanks for your feedback.
1. Regarding the External Wake Up sketch, I seem to have worked this out, but nevertheless the code listed in Unit 4 doesn’t look identical with the code per the link provided in the chapter?
2. The Arduino\libraries folder contains only one servo library – the ESP32_Arduino_Servo_Library folder. It is still problematic for me.
3. It is Aruino\libraries. So I am now encountering issues with the libraries and not clear why or what to do. I suppose I could uninstall everything and delete any remaining files, then start from the beginning?
Sara Santos Staff answered 5 years ago
Hi.
Answering your first publication.
You’re right about the external wake up sketch. When there’s a new library update or something, we always update the code on GitHub first. Then, we update the code on the ebook in the next update. That’s probably what happened in that case. That’s why we provide a link to github in every chapter. The link always contains the most updated code.
You’re having trouble installing the boards because you’ve copied the URL wrong. Here’s the right URL
https://dl.espressif.com/dl/package_esp32_index.json
You’ve typed esperssif instead of espressif. That’s probably why it is not working.
Regards,
Sara

Answering your second publication.
You are right that you only have one servo library on the C:\Users\jack\Documents\Arduino\libraries\ path
But you have another Servo library on the following path (it’s another arduino folder):
C:\Program Files (x86)\Arduino\libraries\Servo\src/Servo.h
Remove the servo library from this folder and try to compile the code again.
Try to follow what I’ve suggested and then let me know if it worked, or if you need further help.
Regards,
Sara
x3mvz5pl5g5k answered 5 years ago
Many thanks Sarah, I now see what happened.
External wakeup – incorrect folder/file structure
Servo – I didn’t realize there was another libraries folder in the Programs/Arduino folder, and a file would ever need to be removed from there
Boards – typo
So that leaves the DHT sketch that I am still unable to resolve. It is sending a GO runtime error?
What are your thoughts? I have run this in the past so uncertain why now I am getting this.
Jack
Sara Santos Staff answered 5 years ago
I’ve searched for a while about that error, and it seems to be happening on Arduino 1.8.10. Is this the version that you’re using?
Some people reporting that error said the error went away after downgrading to Arduino 1.8.9. If that’s you case, you can download arduino 1.8.9 here: https://www.arduino.cc/en/Main/OldSoftwareReleases#previous
Let me know if this solves the issue.
Regards,
Sara
x3mvz5pl5g5k answered 5 years ago
Yes, I recently updated to that version. I tried to reinstall with 1.8.9, but encountered a problem I had before with my laptop where I cannot add the esp32 boards. But this time there is no typo in Preferences. When I search for esp32 in the Boards Manager, it is just blank. Ugh!
Also, I tried to insert an image in this response, but it isn’t working. What is the method?
Sara Santos Staff answered 5 years ago
Hi again.
I think that is a conflict between older and newer versions of the ESP32 packages.
Can you remove the ESP32 board add-on from your Arduino IDE?
Then, open the folder explorer and enter: C:\Users\<YOUR_WINDOWS_USERNAME>\AppData\Local\Arduino15 and press enter key:
Then, delete packages folder inside the Arduino15 folder.
Restart the Arduino IDE.
Then, Install the ESP32 Board in Arduino IDE again: https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/
Tools > Board > Boards Manager
Wait for downloads to finish.
Click “Close”.
Re-open your Arduino IDE. And it should work now.
To upload an image here, you can share a link to Google Drive file, dropbox, imgur.com, or box.com (any file sharing service).
Regards,
Sara
x3mvz5pl5g5k answered 5 years ago
This solved the problem with configuring the board and the sw downgrade also allowed me to successfully upload the DHT sketch. So all is good, and I appreciate taking the time to walk me through the problems.
So it seems Arduino IDE upgrades will sometimes mess up a program. I have heard this to be true of Ubuntu and some other programs. So I guess part of using these platforms in the future will include having to somehow modify programs we develop to make them work, or stay with an older IDE or other platforms. Advantages and disadvantages to both.
Sara Santos Staff answered 5 years ago
Hi.
I’m glad everything is solved now.
Thanks for reporting those problems with the Arduino IDE, because other readers can have the same issues and now we know the reason.
Sometimes it is better to upgrade just after some time the new version is released because new releases have higher probability to have bugs. Usually, I only upgrade my IDE after the new version has been released for some time.
I’ll mark this issue as resolved. If you have more questions, you just need to open a new question in our forum.
Thank you for following our courses and good luck with your projects.
Regards,
Sara
