EC25 MQTT Will Message

Hi,

I am trying to set a simple will message over AT+Command, but I don’t see any will message posted when I disconnected EC25. Please see below AT+Commands:

at+qmtcfg=“recv/mode”,0,0,1
at+qmtcfg=“will”,0,0,0,1,“willtopic”,“willmessage”
at+qmtopen=0,“test.mosquitto.org”,1884

some delay here > 5 seconds, and then I disconnect:

at+qmtdisc=0

What step do I miss here? Thank you.

The will feature needs to be verified on A/B terminal

Thank you for responding. What is A/B terminal?

Terminal A releases offline messages to will topic, and terminal B subscribes to will topic. When terminal A is disconnected, terminal B can receive offline messages

I use MQTT Explorer and I can see will topic when I sent it from Android/iOS app, but I don’t see the will topic when it was sent from EC25. So something is wrong either the way I am sending it from EC25?
