Hello @jgangemi I tried this branch out on my xiao ESP32-S3 and noticed that it was MUCH slower on the initial connection. It did work to flash the device once it finally connected. Worked as expected on the Xiao ESP32-C3 |

Further update: if I use this along with the updated stubs as it is in PR #23 then it does work on both ESP32-C3 and ESP32-S3 boards. |
