Hi all,
I am working on nRF-9160 and nRF-9151, and I wanna know does Serial LTE Modem support will message function for MQTT connection or other connection?
I've asked AI about this, and got a replied telling that parameter "retain" of AT#XMQTTPUB=<topic>[,<msg>[,<qos>[,<retain>]]] might be what I need.
But to what was documented on the page, I'm not sure if this is equivalence to will message function, also I'm not sure about whether I could set/clear the "persistently stored" message with this. Like if I PUB multiple times, will the message stacked up or only modified?
