wolf SSL / MQTTS

MQTT and MQTTS with wolfSSL TSL library

Dependencies:   FP MQTTPacket

Dependents:   YoPlegma

Fork of MQTT by MQTT

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.
