Not sure if it’s my place to answer this question, but if you click on Courses at the top of this page, the books you’ve purchased are available to download, above the ones which are available for purchase.

Hi.
Yes. That’s right.
Just go to this link: https://rntlab.com/courses/
And you’ll find the courses you have access to.
 
In our records, these are the courses:

• Build Web Servers with ESP32 and ESP8266
• Firebase Web App with ESP32 and ESP8266
• Home Automation Using ESP8266 – 4th Edition

 
Let me know if you can access the eBooks.

Sara

Thanks , I thought that the ones I purchased would be more obvious, didn’t click on them for whatever reason. 

I’ll mark this issue as resolved. If you need further help, you just need to open a new question in our forum.
