Four-wheel Drive Attributes:
- AT firmware: This firmware only supports AT commands to operate the module.
- Transparent transmission firmware: This firmware configures the module through the webpage, similar to the router configuration
- ESP8266-12N is an enhanced version of ESP8266-12, perfect peripheral circuit, four-layer board technology, enhanced impedance matching, better signal output, whether it is stability or anti-interference ability, PCB antenna has been tested by professional laboratory, perfect match, After ROHS certification, they have been greatly improved! For users who have previously chosen ESP-12, it doesn't matter if the product has already been made. The enhanced version is fully compatible with the previous firmware. The pin is added with six IO ports and SPI port on the basis of ESP-12. The development is more convenient and application. More extensive!
- ESP8266-12N built-in cloud service function, which can enter the global remote control function with three instructions.
- ESP-12N: Breakthrough design, new four-layer board design, new antenna revision RF performance optimization, 30%-50% increase compared to ESP-12E communication distance! Half-hole patch process, full IO lead-out, with metal shielded case, FCC & CE&RoHS certified, built-in PCB on-board antenna, 4Mbytes of Flash.
- Adding the cloud family group command AT+LANSTART, you can easily join the cloud family group and connect with the APP to control it;
- Added the exit cloud family group command AT+CLDUNBIND, module cloud control transfer? An instruction can exit the cloud family group and is no longer bound by binding;
- Add WPS function, AT+CWWPSSTART directly open WPS, and configure WiFi connection more conveniently;
- The new AT command AT+CIOWRITE can set the IO state, and one command can control the high and low levels of different IOs;
- Added AT command AT+CIOREAD to read IO status, one command can read the status of different IO;
- Add the AT command AT+CSYSHEAP to check the remaining RAM size at any time, and the remaining space is easy to grasp;
- Added AT command AT+CIOADC to read ADC, input voltage range is 0~1V;
- ESP8266, version number: ESP-12N. ESP8266-12N has greatly improved in function, appearance, process, signal strength, etc., perfecting peripheral circuits, enhancing impedance matching, better signal output, and improving stability and anti-interference ability. !

Instructions for use:
- For the module side:
- Use AT to call only one to join the cloud server command, and then directly send and receive data remotely. very simple
- If you don't want to use AT commands to develop, you can use the 8266 SDK with AI-CLOUD embedded to develop.
- For the mobile app side:
- Convenient development environment, free virtual machine and familiar with Linux system, develop directly in Windows environment, save development time, add AT CLDSTART, start cloud connection, the default parameter is Ai-Cloud cloud platform, after executing this instruction, The system automatically maintains the connection and heartbeat packets in the cloud, as well as disconnected wires. The system handles all protocol layers.
- AT CLDSTOP stops the cloud connection. Free all system resources related to the cloud.
- AT CLDSEND=Send data to the cloud.
- The parameter is the data length. After executing this command, the system will return ">", and a certain length of data can be sent at this time.
- Data reception:
- When the cloud data comes, it will receive CLD,:
- Len is the data length, and data is the specific data.
- Smart connection:
- AT CWMODE=1
- AT SMARTSTART=1
- At this point, use ESP_TOUCH technology to configure.
- (The command "AT CWSTARTSMART" can be used directly after version 1.2.0. No need to set parameters, the type of SmartConfig can be obtained automatically, no need to set.
