What is AiThinker-Combo?

AiThinker-Combo is an IOT application firmware independently developed by Ai-Thinker and can be directly used for mass production, aiming at reducing customer development costs and rapidly forming products. With the command of AiThinker-Combo, you can quickly join the wireless network, connect to the cloud platform, realize data communication and remote control, and truly realize the internet of everything through wireless communication.

AiThinker-Combo firmware makes Ai-Thinker module as client and MCU as master. MCU sends AT commands to the module, which controls the module to perform different operations and receives AT responses returned by the module. AiThinker-Combo provides a large number of AT commands with different functions, such as Wi-Fi command, TCP/IP command, Bluetooth LE command, Bluetooth command, MQTT command, HTTP command, GPIO operation command and so on.

AiThinker-Combo outline

The AT command starts with “AT”, which stands for Attention, and ends with a new line (CR LF). Every command you enter will return a response of OK or ERROR, indicating the final execution result of the current command. Note that all AT commands are executed serially, and only one command can be executed at a time. Therefore, when using the AT command, you should wait for the last command to be executed before sending the next command. If the last command is not completed and a new command is sent, the prompt cmd is running... will be returned.

By default configue, MCU connects to Ai-Thinker module through UART, sends AT commands and receives AT responses.
