We’ve retested connections with firmware v1.6.2 and haven’t reproduced this so far.
Could you share your phone model, OS version, and StackChan World app version, along with a screenshot showing the full error? Please hide any device identifiers.
Does the error occur immediately after selecting the device, during Wi-Fi setup, or when reconnecting to an already bound device? Also, was the firmware updated through OTA or M5Burner?
