5-STM32 things development WIFI (ESP8266) + GPRS (Air202) system security papers embodiment (Configuration MQTT SSL certificate, verifying the security communication)
First, determine their own firmware open SSL, firmware upgrades articles which I opened SSL, if they downloaded the firmware SSL will open
If your firmware is not open SSL, you can compile your own
Compiler Reference
6-STM32 things develop WIFI + GPRS Basics (compiled lua firmware NodeMcu 8266)
In fact, very easy to use, after all, it is a one-way authentication, in fact, strictly speaking need to download a certificate to the Wi-Fi module, and I have not downloaded .....
Because I have been using one-way authentication, so no need to download the certificate can be
Only need to modify the code to make changes to the Basics (upgrades piece of test code If you turn on a secure connection will be reported out of memory .....)
According to their modification
Such Wi-Fi connection on the realization of a one-way SSL
