Hello Everyone,
There are many things have been resolved at the github issues. Maybe you should check out.
@betgear: I think that it is reasonable, you should create an issue, so you'll know when I finish it.
@r73_pablog: can you show me an example? I think the best way to know when a sensor has lost the link is keepalive timer. And it is available.

Hi,

the "Last Will and Testament" is part of MQTT protocol.

http://www-01.ibm.com/support/knowledgecenter/SSFKSJ_7.1.0/com.ibm.mq.doc/tt60360_.htm
http://docs.oasis-open.org/mqtt/mqtt/v3.1.1/os/mqtt-v3.1.1-os.html#_Toc385349232

Already support LWT: (Last Will and Testament)
Setup in MQTT_InitClient file mqtt.c

Code: Select allchar willTopic[] = "/lwt";
char willMessage[] = "offline";

mqttClient->connect_info.will_topic = willTopic;
mqttClient->connect_info.will_message = willMessage;
mqttClient->connect_info.will_qos = 0;
mqttClient->connect_info.will_retain = 0;


- Thu Feb 05, 2015 9:09 am #9055 I have imported the MQTT project following the instructions on youtube.
I'm trying to compile and get the following error:

What did I ddo wrong?

- Sat Feb 07, 2015 12:57 am #9157 I have similar problems with Dev Tool v1.08. I use Makefile.windows. The esptool is in the C:\Espressif\utils directory in reality . If I copy the content of the Espressif\utils directory into the C:\Espressif\xtensa-lx106-elf\bin (as is in the Makefile), the error message is the following:
