Step 3: Use lg02_single_rx_tx to transmit

Command:

root@dragino-1b6fb0:~# lg02_single_rx_tx -t -d 2 -f 915600000 –m “hello from dragino” Use radio 2 to transmit a message at frequency 9156000000
Set up a LoRa node to send out LoRa packet, We use LoRa Shield + UNO in this example. The library use in Arduino UNO is LoRa-Master. And the source code is LoRaReceiver.

6. Example 3: MQTT Transfer Mode

MQTT is a machine-to-machine (M2M)/"Internet of Things" connectivity protocol. It was designed as an extremely lightweight publish/subscribe messaging transport. It is useful for connections with remote locations where a small code footprint is required and/or network bandwidth is at a premium. For example, it has been used in sensors communicating to a broker via satellite link, over occasional dial-up connections with healthcare providers, and in a range of home automation and small device scenarios.

Most IoT server support MQTT connection, for those servers, we can use MQTT to connect it to publish data or subscribe to a channel.
