Previously, the LoRaWAN 1.0.x standard was worded in a way that prohibited the network server from retransmitting acknowledgements. Now that LoRaWAN 1.0.4 allows the network server to retransmit the ACK...

I interpreted that part as meaning that we shall not retransmit a downlink frame (retransmission of data frames initiated from the network server). But we can still retransmit the acknowledgement...

I was busy with various things, so I didn't write a response earlier. Anyway, for completeness, I would like to add on. I don't think the existing behaviour is wrong...

If you have control over the network server: are you already using the highest-possible datarate for RX2? By using a higher datarate, you can reduce the chances of collisions, since...

Are you adding only the source code to your project? What about the resources? What's stopping you from just adding Paho as a dependency?

Just a comment on this patch and the original: the function name is misleading. Although UTF-8 is used for MQTT, Java's internal encoding of String's characters is UTF-16. charAt() is...

EDIT: I wrote before that I might have encountered this before, but it could have been something else. Anyway, the rest of this post might be still of some use....

This might be a way to mitigate this condition, by adding a check for the disconnected state with isDisconnected(), to prevent a double-disconnection within shutdownConnection(): ``` // This method could...

As of now, there is no code for reconnecting when the connection is lost. The code for establishing the connection is discarded once the connection is made, to save IOP...
