Ok. I am also testing MQTT connection to Google cloud. Will update if i find any luck.
Thanks. I was wondering how does SIM800 do server authentication? Does it have any certificate installed in it?
I read somewhere that it uses some default certificates for this to do HTTP over SSL.
Not sure how to check them though.
No, i havent tried AWS MQTT yet.
Hi all. The AT+SSLSETCERT command seems to require a password - any idea how to set it or retrieve it after setting a custom SSL certificate?
I have been able to write the certificate file to the memory of the SIM800L but not getting success when I try to import the the certificate. Any ideas?
Any Updates Sir,
I am using Sim900a with arduino but not able to connect to Google cloud core.
For MQTT, it needs TLS 1.2 but Sim900a has specification of TLS 1.0
Please suggest me if I need to change hardware, I am currently prototyping.
No didnt get time yet.
