Troubleshooting ValueError in Raspberry Pi Pico W
When working with the Raspberry Pi Pico W, you may encounter numerous coding challenges, and one common issue is the ValueError: invalid syntax for integer with base 10. This error often arises when handling HTTP requests. In this guide, we'll explore the specifics of this error, particularly in the context of using urequests to retrieve data from an LSW-3 stick logger connected to your network.
The Problem
You might try to set up your Raspberry Pi Pico W to connect to Wi-Fi and fetch a webpage. While the connection to the specified SSID may be successful in your code, executing an HTTP GET request can lead to the ValueError. Here’s an excerpt from a typical scenario:

The intended URL works perfectly in a browser, implying that there’s a misconfiguration or incompatibility in the code for the Raspberry Pico. Understanding and fixing this issue is essential for your project to function successfully.
The Solution
Step-by-Step Implementation
To overcome the ValueError, let’s change our approach from using urequests to leveraging a raw socket connection. Here’s how you can code it effectively:
Import Required Libraries: The first step is to import the necessary libraries for networking and socket management.

Understanding Base64 Encoding
In the above code, the string dXNlcm5hbWU6cGFzc3dvcmQ= is the Base64 encoded format of username:password. Use this format to safely send authorization information. When you encode your credentials using Python, you could use:

Conclusion
By following the steps outlined above, you can effectively bypass the error encountered with urequests and successfully pull the desired data from your LSW-3 stick logger. This method allows more control over your network requests, making it a robust alternative for Raspberry Pi Pico projects.
