Using MQTT with SSL on Lopy

[achide]

Hello,

I recently started MQTT on Lopy, I've followed the tutoriel on youtube. And I successfully connect with broker.
Now I would like to use SSL with MQTT, but I haven't find any description of this part.
Here's my code:
client = MQTTClient('Lopy', server ='192.168.0.103', port =8883,ssl = True, ssl_params= {cert_reqs=ssl.CERT_REQUIRED, ca_certs = 'pycom/ca.pem', keyfile = 'pycom/client1key.pem', certfile= 'pycom/client1.pem'})
And I got error in this line.
I'm not sure but I think ssl_params is not in rignt format.
If someone can help me?

Thanks a lot!

ssl_params is a dict. You shouldn't use = to assign values to dict keys, but :
Also, a key should be a valid Python type (in this case str I guess):
ssl_params= {'cert_reqs':ssl.CERT_REQUIRED, 'ca_certs':'pycom/ca.pem'}

Hi,

You're right! Thank you.
But I have another error, it told me :
OSError: certificate file not found

It's right that I use pem files?
