Helloā€¦both of the XIAO ESP32S3 devices I are own exhibit the ā€œport not availableā€ issue when trying to upload a sketch. While the ā€œLong press BOOT BUTTONā€¦ā€ method works, itā€™s obviously a headache when experimenting with different sketches. Does Seeed Studio have any plans to rectify this design issue? The reason I ask is I like the features and form factor of the S3, and would like to purchase more of them for future projectsā€¦but not if this issue persists. Any feedback you could provide would be greatly appreciated! - Frank

Hello @mi2024
The size of the XIAO has caused us to have to make some trade-offs with the serial chip. Currently, the problem can only be solved by ā€˜BOOT BUTTONā€™.
Thank you for your understanding and support, we apologize for any inconvenience caused!

Thanks for your reply @Seeed_Seraphina. I came across this troubleshooting video that explains why an insufficient capacitor rating might be responsible for the code upload failure issue in an ESP32. The solution is to solder in a 1 microfared electrolytic capacitor between the EN pin and GND. Iā€™m interested in your thoughts on this possible fix.
