* AT + CWSMARTSTART = 0 AI-LINK intelligent connections advantages: '''fast''', the router is compatible with the best available in the phone is not connected to the case under the Wi-Fi configuration. Cons: Wi-Fi will cause the phone offline. Principle and current connection socket using the same small k.
* AT + CWSMARTSTART = 1 ESP-TOUCH intelligent connection Advantages: Wi-Fi will not disconnect the phone Disadvantages: slow, very few router may have compatibility issues.
* AT + CWSMARTSTART = 2 Airkiss intelligent connections advantages: support micro-channel hardware platform. Cons: Almost not own designs APP calls.
