Good again.
I return to post, because I would need the LoPy that receives the txt file is the one that starts the wifi as
wlan = WLAN (mode = WLAN.AP,
ssid = 'Gateway1',
auth = (WLAN.WPA2, 'password'),
antenna = WLAN.INT_ANT)
I have tried to modify the code as I have the partner that works so that it is but I get error everywhere.
Once trying once more, if I do not restart the board and try to execute the code, I always get the error:
Traceback (most recent call last):
File "<stdin>", line 17, in <module>
OSError: [Errno 12] ENOMEM
Because it is ? If someone can give me a hand code please!
