Routing/Tunneling/Bridge

[Joe_Smith]

I am such a beginner at this. Don't even know how to phrase my problem correctly. Do chip in with advice on that so I can begin using the proper question.

I want to turn my bluetooth connection into network using routing or tunneling or both. But believe it's called a bridge.

I'm in need of a comprehensive guide for beginners on how to do this. Even guides for beginners on routing boggles my mind.

At my disposal I have linux but I could very likely to do it in windows if it's easier.

So, can somebody link guides for dummies or perhaps other forums with people that can help me. Or help me here if you have the time. Would be MOST appreciated.

welcome here,

what is the end result you desire?

Bluetooth is a very limited range which requires a transmitter and a receiver.

Thank you.

The endgame is to make bluetooth into a network protocol such as ethernet if possible. Then I can gain connection with a software that doesn't connect with mac addresses.

Do you want the connection to be wired or wireless? If wireless is OK, there are a number of off-the-shelf industrial adapters that will convert bluetooth to wireless and act as the network access point for that device. Those are very easy to set up: establish a normal bluetooth relationship, then configure the adapter for the wireless network it will use.

At this point, I'd ask if you have security requirements for the solution, as if you're providing a bluetooth-wireless connection for a device that should be isolated, then that's a no-no. Also, there's a question of reliability: bluetooth connections may require manual re-establishment after an outage, while wireless can resume automatically. If the solution requires a high degree of uptime, you may need a higher-end device or one that uses a USB-wireless connection, if a USB port is available.

I vaguely remember seeing something like this, internet sharing over Bluetooth. I haven't done this recently if ever. Wifi hotspot works well.

So there must be already programmed capabilities for network over Bluetooth. But why would anyone want to use it when wifi is pretty much the same / better and works.

If the device has BT but not wireless, then it requires the bridge to get to the Internet. This could be a case with an industrial device that normally doesn't connect to the Internet, but which needs to have a temporary connection for a vendor to download code to flash the BIOS or something like that.
