Connection failed; try to connect m/xdot to a conduit AEP

Hi All,

I have tried to use the link below,

http://www.multitech.net/developer/software/lora/getting-started-with-lora-conduit-mlinux/

to try to connect my xdot or mdot to Multi-tech conduit model AEP. But when I use AT+SEND, the message was not sent due to “Network not joined”. As consequence, nothing will show in Node-RED.

So does anyone has experience with setting up m/xdot with conduit AEP before or recommend any setup guide?

Thanks
