MQTT and MQTTS with wolfSSL TSL library
Fork of MQTT by
MQTT is light weight publish/subscribe based messaging protocol for M2M, IoT. This library was forked from MQTT https://developer.mbed.org/teams/mqtt for adding MQTTS security layer on the protocol. TLS(SSL) part of the library is by wolfSSL.https://developer.mbed.org/users/wolfSSL/code/wolfSSL/
"connect" method was extended for TLS. Rest of API's stay compatible with MQTT.
connect methode
int connect(char* hostname, int port, const char *certName = NULL, int timeout=1000)
The 3rd argument certName can be following values.
- NULL: connecting with MQTT
- pointer to certificate file: connecting with MQTTS. PEM or DER for server verification.
- pointer to NULL string: connecting with MQTTS without server verification. This option is for prototyping only, not recommended in security perspective.
