📌 Install NanoMQ MQTT Broker on Luckfox Pico Ultra W

This guide provides step-by-step instructions to install and run the NanoMQ MQTT broker on a Luckfox Pico Ultra W.

1️⃣ Download NanoMQ Package

Run the following command to download the NanoMQ .deb package:

wget https://www.emqx.com/en/downloads/nanomq/v0.18.2/nanomq-0.18.2-linux-armhf.deb

2️⃣ Change File Ownership (Fix Permission Issue)

Set the correct ownership to prevent permission errors when installing:

sudo chown _apt nanomq-0.18.2-linux-armhf.deb

3️⃣ Install NanoMQ

Run the following command to install the downloaded package:

sudo apt install ./nanomq-0.18.2-linux-armhf.deb

4️⃣ Start NanoMQ

Once installed, start the NanoMQ broker:

nanomq start -d

5️⃣ Verify Installation

Check if NanoMQ is running:

ps aux | grep nanomq

If it's running, you should see an output with nanomq listed.

6️⃣ Configure NanoMQ (Optional)

To modify NanoMQ settings, edit its configuration file:

sudo nano /etc/nanomq.conf

After making changes, restart NanoMQ:

nanomq restart

7️⃣ Test NanoMQ Broker

Subscribe to a topic

Open a terminal and run:

mosquitto_sub -h localhost -t test/topic

Publish a message

In another terminal, send a test message:

mosquitto_pub -h localhost -t test/topic -m "Hello, NanoMQ!"

If working correctly, the subscriber terminal should display:

Hello, NanoMQ!

8️⃣ Get Device IP for MQTT Connection

To connect external clients, find your device’s IP address:

hostname -I | awk '{print $1}'

Use this IP with port 1883 in your MQTT client.

🎉 NanoMQ is now installed and running! 🚀

You can now use NanoMQ for MQTT-based IoT applications on the Luckfox Pico Ultra W.
