MQTT subscription not working

[JojoS62]

Is this the actual version? I found the MQTT subscription is not working, the topic is not valid:
sprintf(subsciptionMask, "%s/%03d/#/down", MQTT_ROOT, theConfig.networkId);
The /down part is not allowed after the /#, but an /+ is ok. When the SensorID is appended then the correct topic name is: "%s/%03d/+/down/+"
I've modified the fork for sending and receiving strings, that works also fine.
Thanks for sharing your code.

I saw your comment, long ago when i just started going the path of this project, but at the time i understood nothing about this issue, now that i have solved the problem in the same way, i gave you a thumb up for your solution. i wish i could understand it before.

another part i had to change in the code of Gateway.c, is where a recieved message from mosquitto is scanned with the missing part of the sensor ID, leading to sending a message to DeviceID=0, and not the correct one.
had to change 2 lines from:
sscanf(msg->topic, "RFM/%d/%d/%d", &network, &data.nodeID, &data.sensorID);
to:
sscanf(msg->topic, "RFM/%d/%d/down/%d", &network, &data.nodeID, &data.sensorID);

The p^rocess monitor the MQTT server an look for notification on its channel (RFM/....). You need to publish on the same MQTT server on the appropriate topic and the information will be carried by the system.
