Hi all, I just received my WiPy 2.0 board and I`m having trouble doing anything with it. So far I`ve only succeeded to login with pymakr on my mac. But the minute I do wlan=network.WLAN(mode=network.WLAN.STA) it stops working. Ftp(using FilZilla) sort of succeeds. I can`t view the files inside the /...

Great! Thanks for the feedback :-) Hi dani, I'm having an issue connecting to a secure site. I'm using the esp8266 Node MCU w micropython 1.8.6 I think the problem is that the ssl module does not support server certificate validation. "ssl_handshake_status:-256" Do you any possible solution to this...

>>> sock=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
>>> import ussl as ssl
>>> s=ssl.wrap_socket(sock)
ssl_handshake_status: -256
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
OSError: [Errno 5] EIO

Running this on the Esp8266 NodeMCU and Micropython Version 1.8.6

Was the socket.IPPROTO_SEC variable removed from Micropython 1.8, since most examples online have it. If not, is there any way I could get the variable, without having to rebuild the whole firmware?
