Issues on Radiacode 102 via USB

[leandroalbero]

Describe the bug

When running any of the examples with a Radiacode 102, the program execution stops after a while

To reproduce

Start any of the included examples, in this case I have used webserver.py

Desktop/FW:

• OS: MacOS Sonoma (23A5276g)
• Packages installed by the poetry env.
• Radiacode 102
  • FW v04.02
  • BOOT 04.00

Let me know if you need any more information, I don't know if the 102 is supposed to even work with this library. Note: I've checked #9 , but still facing this issue on v0.2.0 Thanks!
