Crash when attempting to connect to printer
When calling cat.connect() while the printer is on, my ESP32S3 crashes with the error message below. I have tried following the example code, with the only change being that I hardcode the BLEAddress so the board can actually find the printer.

Not working with MX09/Esp32-S3
I finally managed to build and upload your print demo example, but the Esp32-S3 does not connect to MX09 cat printer.
I used the setup instructions from: (https://github.com/teastainGit/LilyGO-T-display-S3-setup-and-examples)
Attaching the serial output.

Could not find printer with MX10
Hello,
I facing an issue with my MX10 printer. I replaced the string here but it still having this issue:
cat.addNameArray((char *)"MX10");
Error
08:49:20.538 -> Could not find printer!
Is there a debug mode?
Other tests
Scan
- The printer is detected by a BLE scan tool:

Bad include filename in example
Just tried to run the example and figured out that catGFX.h no longer exists instead <catprinter.h> would be apropriate. Maybe this is worth correcting....
