I attempted trying to get the build toolchain set up on my Linux box a few months ago and after a few hours of troubleshooting errors I just gave up on it. I switched to the Docker route and it just worked out of the box. That said, I was already using Docker for other projects so installing it wasn...

I haven't tried 1.17 myself yet since it just came out, but I do have 1.16-1m running on several ESP-01 and ESP-01S modules right now with 2.4G WiFi using WPA.

The code that you posted should be all you need to connect. It matches what I use.

If you are using one of the newer builds (1.16 or 1.17) you can use the new mpremote CLI tool: which will copy the file from your local drive to the ESP device.

WiFi works just fine on the ESP-01S. I think @Roberthh is correct, the esp8266-20191220-v1.12.bin file requires a device with 2M or more of flash and the standard ESP-01S only has 1MB. If you use a MicroPython firmware build set up for 1MB flash like esp8266-1m-20210902-v1.17.bin it might solve your...

When I try in MP v1.16 on an ESP8266 it gives me a result of 18

library of MFRC522 This isn't really specific enough to give you much help tbh. Maybe have a look at this post and see if it helps: https://forum.micropython.org/viewtopic.php?t=1980 Someone created a driver for the MFRC522 but it doesn't look like it has any recent activity so it might not be main...

I agree with @jimmo, this is likely a Thonny issue and has to do with where you are trying to save the file.

You might want to check the Thonny wiki or ask about it on the Thonny forum

Thonny doesn't really compile anything. What RFID library files are you trying to use? Are they pure Python or do they have C dependencies?

When you use the global keyword in a function to declare a variable in that function as being global, the variable must have been previously defined (i.e. assigned a value) at the module level, outside of any functions in that module (in other words, the .py file itself). In Python, it's the fact th...

I've copied files other than .py with Thonny before. Using the file panel on the left, right-click the file you want to copy on the local drive at the top of the panel then and select Upload to / (or whatever the cwd of the device is). Alternatively you can use WebREPL or the new mpremote CLI tool: ...
