This is quite inefficient protocol for LoRa, because packet lengths are much longer than AX25, especially if compressed packets are used, which causes longer TOA (time on the air). # Bluetooth terminal applications Set `cfg.EnableTextPackets/CFG_TEXT_PACKETS` to `true` to use modem for sending text based messages through Bluetooth terminal applications. \ No newline at end of file
