OTA Online Upgrade for Arduino

1. Introduction to OTA

OTA stands for Over-the-Air, which refers to the technology for remote management of SIM card data and applications through mobile communication (GSM or CDMA) over the air interface. The air interface can utilize WAP, GPRS, CDMA1X, and SMS technologies. The application of OTA technology allows mobile communications to not only provide voice and data services but also to offer new business downloads. In the Internet of Things (IoT) field, especially in embedded devices like the ESP8266 Wi-Fi
