![]() ![]() It simply appears as a serial stream that you can communicate with exactly as you would with any other serial device. I’ve used this method to connect to the sparkfun Bluetooth Mate Gold. Once you’ve connected to the serial bluetooth device with screen, the connection will be held active for the length of your session. Download, optionally install, and run the PuTTY executable Set Connection Type to SSH Set Host Name (or IP address) to the Opengear devices IP address Set Port to 22 Click Open To connect to the CLI of the Opengear itself: Login as root or a users or admin group user, e.g. ![]() Then you will be able to see the device in the list of devices. You must simply make sure that the bluetooth device is paired and active. Although you can use Terminal.app for SSH connections, there are still some benefits to using Putty such as other clients failure to keep connections. SSH is available by default on Mac, Linux, or Unix. ![]() This method works equally well if you want to connect to a serial bluetooth device. Official versions of Putty are available on Unix-like platforms, and now its widely available for Mac systems running OS X 10.11 or later. Press “y” and you’ll be back to your shell terminal. Screen will then prompt you to quit and kill all of your windows. To exit (and close the screen gracefully) press: control-a Once you’ve connected, you can use the terminal as you normally would. Remember to specify the speed (baud rate) after the device name. Once you’ve determined which device you would like to use, you can execute the SCREEN command to start the serial terminal session on your Mac. if everything went well, you should see the black window of the serial connection. The settings are: Connection type: Serial Speed: 115200 Serial line: COM3 (in your case the port may be different). ![]() The first thing to do is determine which device you want to connect to. Once the driver is installed, configure the serial connection in putty like shown below. This works well particularly if you have an RS-232 serial to USB converter. There are a few software apps out there, but I find it much simpler to simply use the terminal application “screen”. The frequency of execution can be controlled with another Autohotkey script or, as in my case, with the Windows Task Manager.If you develop on an Apple and find yourself doing any sort of device or embedded development, you will quickly find the need for a serial terminal on Mac. Start PuTTY if it's not already runningįormatTime, TimeString,yyyy-MM-dd HH-mm-ssĬontrolSend,, %TimeString%, %putty_name% Both of these can be hard coded but I wanted to keep the variables separate from the functions. location_putty() is the location of the PuTTY executable. oasis_putty_name() is the name of the PuTTY window once it's open, it will depend on the COM port selected. If PuTTY is not open it will start the saved session. The following Autohotkey function can send a command to the already open PuTTY session. Another solution which I have used to regularly send commands to a device uses a combination of PuTTY and Autohotkey.įor the initial setup, configure a PuTTY session and save it. ![]()
