Re: [mosquitto-dev] Options not sent with mosquitto_subscribe_v5 (v. 1.6

[David Gurr <davidgu@xxxxxxxxx>]

And again correcting my own misconceptions ... MQTT_SUB_OPT_NO_LOCAL is sent directly to mosquitto_subscribe_v5 as below, but first you must request the v5 protocol before connecting:

    mosquitto_int_option(mosq, MOSQ_OPT_PROTOCOL_VERSION, MQTT_PROTOCOL_V5);

Resolved my own problem ... realised that you don't pass the option value directly, but by adding them to the struct mosquitto via the options functions.

Sorry for the dumb question!

The following code doesn't seem to be sending the requested option:

            retval = mosquitto_subscribe_v5(mosq, NULL, buf, 1, MQTT_SUB_OPT_NO_LOCAL, NULL);

I still get my own published messages received by this client. The log callback seems to show that the options are sent as 0x00:

Client mosq-evfqJnVOdLsQZ900sL sending SUBSCRIBE (Mid: 2, Topic: cmnd/office_heater/POWER, QoS: 1, Options: 0x00)

Am I doing something wrong, or is this a bug?
