Please, I need help. In August I made a simple app using the serial component. It worked normally with the ESP32. Now in September, I made the same app using the serial... and it just doesn't work anymore. It connects, but any char I send.... It won't. I've already tested the ESP32 code with the USB terminal app... works round with with the mobile x ESP32. I've tried other extensions and they don't work. The strange that on September 14 there were updates in the Appinventor and on September 15 I made this new app. Does anyone have or have had this problem????
