An amendment to the restart frequently executed serial AT commands problem with large amounts of data stops responding problem
2 no longer picky serial debugging software, support PuTTY, SecureCRT and other serial debugging tools, the AT command at the end, is not mandatory \ r \ n, CR or LF can, CRLF can
3 AT + CIPAP? AT returns the IP address of the module current AP mode + CIPAP = "192.168.4.2" Setting the IP address of the AP mode
4 AT + CIPSTA? View IP address AT STA mode + CIPSTA = fixed IP "192.168.1.2" STA mode setting above operations are effective immediately without restarting
5 AT + CIPAPMAC query the current MAC address of the AP mode settings for the current MAC address of the AP mode AT + CIPAPMAC =? "1a: fe: 34: 9e: 34: a9"
6 AT + CIPSTAMAC exercise MAC address AT STA mode + CIPSTAMAC =? "18: fe: 34: 9e: 34: a9" AP mode settings for the current MAC address
7 AT + CIOADC command reads the ADC value Note: ADC input voltage range is between 0V to 1V! 0 to 1024,10 bit precision
8 AT + CIOREAD command reads the GPIO AT + CIOREAD = 0 reads GPIO0 level assumptions GPIO0 is high, it will return 1: HIGH, otherwise it returns 0: LOW GPIO range of digital, GPIO0, GPIO16 can
9 AT + CIOWRITE command to set the GPIO AT + CIOWRITE = 0,0 setting GPIO0 level is low AT + CIOWRITE = 16,1 set of high level GPIO16
