Regarding send fail, past issues (closed issues) are helpful. Mostly due to terminating resistors or cable quality. Many people have encountered this problem and solved it by changing the terminator...

>Should i switch out the board part number? If you use bluepill or blackpill in Platformio.ini, it will be 72Mhz. It has nothing to do with this issue. But everyone...

I think you can build custom boards using BluePill and BlackPill variants. However, the GPIO of the Serial object changes for the Generic board, BluePill, and BlackPill. The output destination...

Keep STAB length as short as possible.

If you have a BluePill or BlackPill, you can identify the problem. Try BluePill or BlackPill.

There may be a problem with your custom made PCB. If it works fine with BluePill/BlackPill, then there may be a problem with your custom made PCB. BluePill/BlackPill works absolutely.
