Hi Roger,
I first started the subscriber:
root@clanton:~# mosquitto_sub -d -t sensors/valueClient mosqsub/2614-clanton sending CONNECT
Client mosqsub/2614-clanton received CONNACK
Client mosqsub/2614-clanton sending SUBSCRIBE (Mid: 1, Topic:
sensors/value, QoS: 0)
Client mosqsub/2614-clanton sending PINGREQ
Client mosqsub/2614-clanton received PINGRESP
And then try sending messages:
root@clanton:~/mosquitto-1.3.1# mosquitto_pub -d -t sensors/value -m "test"
Client mosqpub/2617-clanton sending CONNECT
Client mosqpub/2617-clanton received CONNACK
Client mosqpub/2617-clanton sending PUBLISH (d0, q0, r0, m1,
'sensors/value', ... (4 bytes))Client mosqpub/2617-clanton sending DISCONNECT
root@clanton:~/mosquitto-1.3.1# mosquitto_pub -d -t sensors/value -m "test"
Client mosqpub/2626-clanton sending CONNECT
Client mosqpub/2626-clanton received CONNACK
Client mosqpub/2626-clanton sending PUBLISH (d0, q0, r0, m1,

Still the same the messages don¹t arrive at the subscription part.
