Hi Gordon, thanks for the answer.
So to make it work it is enough to set idle timeout on both sides and proton will handle rest? Is heartbeat being sent by pn_transport_tick() ? If so in what event it should be sent? In PN_TRANSPORT ? Regards, Tomas 2015-07-28 11:01 GMT+02:00 Gordon Sim <g...@redhat.com>: > On 07/28/2015 08:17 AM, Tomáš Šoltys wrote: > >> Hi, >> >> I am looking for a way hot to send a heartbeat.
