I am seeing this error in my console when trying to get the sms notification module to work with a raven xe.
Error sending notification to 1xxxxxxxxx
java.io.IOException: Did not receive ack packet for outbound message
What does this error message mean? Is there some kind of handshake between the modem and the gateway that has to happen when sending a message?
My setup is probably a little different than most, as my gateway resides in the cloud, so the raven xe is not on the same local network. I am reaching the raven thru a vpn to my cellular mvno. The raven receives a private static ip address from the mvno as its wan/cellular ip address, and that is what I am using as the ip address in the notification settings.
