Codigo ap.py (arranca en modo punto de acceso y arranca la consola REPL via web )

print("ap.py"); 
import network; 
ap_if=network.WLAN(network.AP_IF); 
print(ap_if.ifconfig()); 
ap_if.active(True); 
import webrepl; 
webrepl.start();

crear el archivo ap.py desde la consola

f=open('ap.py','w')
f.write('print("ap.py"); ')
f.write('import network; ')
f.write('ap_if=network.WLAN(network.AP_IF); ')
f.write('print(ap_if.ifconfig()); ')
f.write('ap_if.active(True); ')
f.write('import webrepl; ')
f.write('webrepl.start(); ')
f.close()

Para mostrar el archivo desde la consola:

f=open('ap.py','r')
f.read()

Codigo sta.py (arranca en modo cliente(station) y arranca la consola REPL via web )

print("sta.py"); 
import network; 
sta_if=network.WLAN(network.STA_IF); 
sta_if.active(True); 
sta_if.scan(); 
sta_if.connect("Honor 6X","polkawifi"); 
import webrepl; 
webrepl.start();

crear el archivo sta.py desde la consola

f=open('sta.py','w')
f.write('print("ap.py"); ')
f.write('import network; ')
f.write('sta_if=network.WLAN(network.STA_IF); ')
f.write('sta_if.active(True); ')
f.write('sta_if.scan(); ')
f.write('sta_if.connect("Honor 6X","polkawifi"); ')
f.write('import webrepl; ')
f.write('webrepl.start(); ')
f.close()
