Hi, I'm currently building a system to communicate with remote, low-power, gps-enabled devices.
My broker host machine is 64bit Ubuntu, and my version of mosquitto is straight out of the Precise repository. The embedded devices are ARM, 32bit linux with *uclibc-3.4.6-gcc cross compiler*. On the host machine, and python environment, I'm very productive building what I need to do, and the broker and clients function without a hitch. On the embedded devices, I took the *mosquitto-0.15* source code and cross-compiled with the ARM compiler mentioned above. I modified the makefile such that I only build *libmosquitto.so.0*, and then use this library to build my clients for the devices. My broker is on my ubuntu machine, and I do not require the broker on the devices. I also had to modify *net_mosq.c* such that #define AI_ADDRCONFIG 0 is enabled. Is this the correct approach? What I am finding is that the devices are able to connect, publish and subscribe to messages from the broker, however the *mosquitto_will_set(..)* method does not seem to be functioning at all. I am getting a success return code when initialising the will_set call (just prior to to the connect call as per the doco). But when power is cut and device drops out, the broker never sends the will message as expected.. Any words of wisdom or guidance would be greatly appreciated! regards Paul Lourenco
