• The OTA update and upgrade is enabled by default. After the WiFi configuration is complete, you can select T-Wristband from the port in the Arduino IDE to perform wireless upgrades to get rid of the constraints of downloading the data cable. Please update your own code. Please keep the ota upgrade part, otherwise the upgrade may cause failure Air upgrade again
