Ser2net is installed on the server and shares the serial port on the network and socat is installed on the client and provides the interface there. the Bluetooth adapter from BlueGiga or a Z-Wave adapter like the one from Aeotech, the solution can be the combination of ser2net and socat. If you now have a USB adapter that looks like a serial interface, e.g. Solution 2: ser2net and socat for serial USB ports sudo modprobe vhci-hcdįor the removal of the connection refer to the above mentioned blog article “ Linux, RPi and USB over IP updated” Attention: On a Raspberry I did not succeed in integrating the adapter. The Bluetooth adapter is now shared on the network and can be integrated with the following commands. : Wireless / Radio Frequency / Bluetooth (e0/01/01) Exportable USB devicesġ-1.3: Cambridge Silicon Radio, Ltd : Bluetooth Dongle (HCI mode) (0a12:0001) The result of the list command should be something like this. IP address should be replaced with the IP address of your server. After that we can check if our enabled adapter is visible. sudo usbip -debug bind -b 1-1.3Īnd now we come to the client side, the openhab server. With a bind it is bound and shared on the network. The one we are looking for has the bus id 1-1.-3 and is a bluetooth adapter. : SMSC9512/9514 Fast Ethernet Adapter (0424:ec00)Ĭambridge Silicon Radio, Ltd : Bluetooth Dongle (HCI mode) (0a12:0001) Then the usbip daemon is started and the matching USB adapter is identified and shared. We omit the check whether the kernel is prepared for it, since this is usually the case in current kernels sudo apt install usbip Hierzu muss zunächst usbip installiert werden. The guide is based on the blog entry “ Linux, RPi and USB over IP” by Piotr Król and is a little shortened here.Įrste Schritt ist das Aufsetzen des Servers, an dem der USB Adapter angeschlossen ist. Disadvantage: I got it to run on the server (the one with the adapter), but not on the openHAB site (the client) yet. In contrast to the ser2net / socat combination, this solution can be used for any USB port. And openhab runs on a Raspberry Pi 3 with SSD and a manually installed openHabian and Raspbian Stretch (Kudos to 1: USBIP for non-serial USB ports I use a first generation Raspberry Pi with DietPi as OS for the server (which comes with the adapter). The server on which openHAB runs is always referred to as the client and the server to which the respective adapter is connected is referred to as the server. For serial ports the combination of ser2net and socat and for USB ports usbip is a possible solution.īefore we start, here are some definitions. In order to solve this problem, there are two solutions, depending on the task, which are briefly presented below. However, if the cable length is limited or the installation of cables is not possible, this does not lead to the desired success. To improve the range, the corresponding adapters can be connected with extension cables. Services such as Zwave or Bluetooth are limited in their transmission range for technical reasons. This tutorial is the result of my efforts to use Vlad Kolotov’s Bluetooth binding (kudos to ) for my MiFlora plant sensors. As promised, here comes the tutorial on forwarding serial or USB ports to openHAB.
