How to take the file 'ca.pem' to ‘/flash/cert/’?

[DongYin]

@livius
I used 'freshftp' before, i can see the flash directory by this tool, but can't write file to flash.
then i used 'Filezilla', an error come out :"GnuTLS error -15: An unexpected TLS packet was received"
is there any settings required?

@DongYin
could you show some sample code?
it is something near this?
https://docs.pycom.io/pycom_esp32/library/ussl.html

import socket
import ssl
s = socket.socket()
ss = ssl.wrap_socket(s, cert_reqs=ssl.CERT_REQUIRED, ca_certs='/flash/cert/ca.pem')
ss.connect(socket.getaddrinfo('cloud.blynk.cc', 8441)[0][-1])

@livius
This is my ssl code.and WiFi is connect.
s = socket.socket()
#s = socket.socket(socket.AF_INET, socket.SOCK_STREAM, socket.IPPROTO_TCP)
ss = ssl.wrap_socket(s, cert_reqs=ssl.CERT_REQUIRED, ca_certs='/flash/cert/client.pem')
ss.connect(socket.getaddrinfo('192.168.119.38', 43416)[0][-1])

@livius
only socket is OK.
s = socket.socket()
s.connect(socket.getaddrinfo('192.168.119.38', 43414)[0][-1])
