@Sycrosity 🙏
I am a beginner in Rust development. If there is anything wrong with my question, please point it out. Thank you for your reply.

Hi @lijiachang! I have been quite busy recently and so havn't had much time to work on this project, so only getting round to this now.

While your rustc version is 1.82.0, what is the rustc version of your esp toolchain? You may need to run espup update, and then reload your shell - I am not getting the same error when running it on my device.

It may also be worth doing a cargo update, if you havn't already.

[Sycrosity]

I tracked the issue to an older esp-backtrace line 95 (as stated in your error message), which seems to have a tag for nightly versions before or after a certain date - I would assume its related to this in some way?

[Sycrosity]

I believe the issue was down to me not updating esp-backtrace yet, which has now been done - this should no longer be an issue. (fixed by #19 )

[lijiachang]

coool,
use your latest code , there is no errors for me, Thanks @Sycrosity 🤠

[Sycrosity]

Thanks for the issue!
