pub0sub1.c and pub0sub1_nb.c do not work (receive message)
qos0pub.c published properly (I gor the message with java client.
Environement: windows 7.
NOTE. I updated transport.c for Windows: call to WSAStartup() to initialize socket library
Any idea.?
Thanks

Iâ��m trying to use the Embedded MQTT C/C++ Client, following exactly Benjaminâ��s CabÃ©â��s webcast, with the TI CC3200. In contrast to him I get a lot of errors/warnings (see build log below). Has the Embedded MQTT C/C++ Client been changed since the Benjaminâ��s webcast? The oob project (that Iâ��m using with the MQTT client) without the MQTT client library builds without problems.



Thanks.

Guy
