安信可 HTTP server with TLS support using mbedTLS示例¶

HTTP server with TLS support using mbedTLS¶

Simple HTTPS example that uses mbedTLS to establish a secure socket connection using the certificate bundle with two custom certificates added for verification》

Configure WiFi Connected¶

Please configure the ssid and password that need to be connected to WiFi in advance,in main.c.

#define ROUTER_SSID "your ssid"
#define ROUTER_PWD "your password"

Compile and download¶

Compile command¶

make -j16

`-j16`is the number of cores in the system.

make flash p=/dev/ttyUSB0 b=921600

`/dev/ttyUSBx`is the port number of the Ai-WB2 connection, usually ttyUSB0
