Yes, the LoRa works. I can send the commands and I receive them without problems. It is only when the 2 work together that I get problems. Like I mentioned, when starting everything up I establish a connection between the remote and speaker. I then read how many songs are on the SD card upon receiving a "hello" message from the remote and send the number of songs to the remote. I then choose what song to play on the remote and send it back to the "Speaker". Everything works up until this point. If I receive a data packet while the mp3 is playing, the dfplayer shuts down.
