Hi!

We are trying to used "predefined topics" new feature. We enable PredefinedTopic usage on "gateway.conf" and let "predefinedTopic.conf" as the one that its provide as an example.

Then we try to subscribe using the command line using the following command

./mqtt-sn-sub -p 5223 -T 1 c -q 1 -i "GatewayTestClient"

or

./mqtt-sn-sub -p 5223 -T "1" c -q 1 -i "GatewayTestClient"

but we get an error:

ERROR SUBSCRIBE error: Rejected: not supported

The GW log shows

20180719 101437.847   CONNECT           <---  GatewayTestClient                   04 04 01 00 0A 47 61 74 65 77 61 79 54 65 73 74 43 6C 69 65 6E 74

Thank you for your information.
pre-defined-topic file name setting was incorrect.
I think that this is the cause.

Sorry for my delayed answer, but I was on vacations.

We are testing last GW version we just downloaded.

When we start the GW we see the prompt:

We try to subscribe predefined topic 1:

./mqtt-sn-sub -p 5223 -T 1 -c -q 1 -i "GatewayTestClient"

And all works as expected, but if we disconect from de GW and try to subscribe again we get the error

2018-07-30 09:55:53 ERROR SUBSCRIBE error: Rejected: not supported

The GW log shows:

If we stop the GW and relaunch it again, we can subscribe to the topic. But it only works the first time, then the error occurs.

Thanks in advance for your support.
