Hi,  
I'm using a CoAP request node to send message to a coap-server hosted on a distant machine.  
I can't find the way to choose the CON (confirmable) or NO CON (non confirmable) option. There's no options regarding the confirmation option in the popup. Therefore, by defautlt, all the messages sent use CONFIRMABLE flag ; this is correct but I need to perform tests without this flag enabled.

The installed palette is "node-red-contrib-coap", it's the last version.

Can anybody has an idea about this ?  
Thanks.

Mike

It’s not one of the core nodes so you may need to contact the author direct via that node’s project page.
