Introducing a companion for goMarkableStream: QR Code Generator to easily launch the goMarkableStream (alien.top)

Hey reMarkable Community! 👋 I've been using my reMarkable for streaming a while now, and one thing that started to get on my nerves was the constant need to check the device's IP address just to launch a stream over Wifi (I use goMarkableStream).

I searched high and low for an easier way to access this information, but came up empty-handed. So, I decided to take matters into my own hands and create a utility to solve this issue.

🛠 Introducing the reMarkable IP QR Code Generator!

This little tool (currently experimental) is designed to streamline the process of accessing your reMarkable’s IP address. Here’s how it works:

  1. 📡 The utility constantly checks for changes in the reMarkable’s network.
  2. 🖨 If a change is detected, it generates a QR code containing the IP addresses and outputs it to a PDF file.
  3. 🖥 You can then display this PDF directly on your reMarkable.
  4. 📱 Simply scan the QR code with your mobile device to view and access the IP addresses. more info on the GitHub repository

Cheers and happy streaming! 🎉

Neat -- but also, reMarkable is configured with mDNS, and so you can probably just reach it with remarkable.local instead of an explicit IP.

Yes, on my local network it works. But when tethering with the phone or via a controlled Wi-Fi, it can help

Doesn't work for me for some reasons, had to use the ip

[–] kg4zow@alien.top 1 points 1 year ago

I see a qmdns-responder process running on the tablet, and in the source code I see a function which sends mDNS messages.

However, on a Linux server runing avahi, avahi-browse -ack doesn't show anything involving "remarkable", "rm2", or RM110-xxx.xxxxx (the custom hostname I'm using on the tablet). (It does show all the other mDNS services running on my home , so it is working.)

When I use tcpdump to sniff traffic from the tablet (both IPv4 and IPv6), it's not showing anything on port 5353/udp.

How did you make the name remarkable.local. resolve? Did you manually add a remarkable.local. hostname to your workstataion's mDNS service database, or add a static entry in a local unicast DNS server maybe?

Nice, maybe you can also run the tool as a service like https://github.com/Evidlo/remarkable_printer/

Good idea
