You can use the at command just like a object operation instead of entering serial command each time.
And since it has a class encapsulation, we can control several at object at the same time and interact between these objects.
usage:
step1:run python and import this lib
step2:define a AT object, which is decided by the uart port.
step3:run a single command
This is a ipython sample case:
Code: Select all
In [1]: import at_class as at #import lib
In [2]: t2=at.at_esp8266(2) #define an instance
In [3]: t2.at_scan_ap() # use the method
AT+CWLAP
Out[3]:
['+CWLAP:(4,"michael",-82,"78:a1:06:56:7a:0a",1)',

'+CWLAP:(4,"TP-LINK_C854",-41,"14:75:90:ff:c8:54",11)']
In [4]: t2.at_conn_ap('TP-LINK_3E392E','19881215')
AT+CWJAP="TP-LINK_3E392E",""
conn TP-LINK_3E392E OK
Out[4]: True
In [5]: t2.at_set_mode(3)
AT+CWMODE=3
cur mode 3
set mode--->3 OK
Out[5]: True
In [6]: t2.at_get
t2.at_get_ip t2.at_get_mode t2.at_get_softap_info
t2.at_get_mac t2.at_get_mux
In [6]: t2.at_get_ip(0)
Out[6]: '192.168.1.109'
In [7]: t2.at_get_ip(1)
Out[7]: '192.168.4.1'
In [8]: t2.at
t2.at_conn_ap t2.at_ipsend t2.at_set_mode
t2.at_get_ip t2.at_ipserver t2.at_set_mux
t2.at_get_mac t2.at_ipstart t2.at_set_softap
t2.at_get_mode t2.at_ipstatus t2.at_set_tcp_server
t2.at_get_mux t2.at_quit_ap t2.at_tcp_client_signle
t2.at_get_softap_info t2.at_rst t2.at_udp_client_signle
t2.at_gmr t2.at_scan_ap t2.at_udp_server_multi
t2.at_ipclose t2.at_set_ipmode t2.at_udp_server_signle
or you can run it directly in the script:
Code: Select all
if __name__ == '__main__':
at_test = at_esp8266(2)
at_test.at_set_mode(1)
at_test2 = at_esp8266(5)
at_test2.at_set_mode(3)
This script is just an example, you can change it to fit your application.
Have fun!
