![]() If you are using the Chrome web browser (version 89 or higher) on Windows, Mac, Linux, orĬhromebook, you can use the web-based USB serial monitor. To close (kill) a screen session, press Ctrl-A then press k. Then issue the command: screen /dev/ttyACM0 It should return something like /dev/ttyACM0. Linuxįind the serial port that is being used using the Terminal program command line: ls /dev/ttyACM* Screen allows you you both send characters to the Photon or Electron as well as receive them from the USB serial device. Then issue the command: screen /dev/cu.usbmodemFD1161 It should return something like /dev/cu.usbmodemFD1161. Macįind the serial port that is being used using the Terminal program command line: ls /dev/cu.usb* This is the configuration screen for PuTTY:Ĭlick Serial (1) then enter the COM port number (2) then click Open (3). It's hard to say what COM port your Photon or Electron will use, but if you open the Windows Device Manager and expand Ports (COM & LPT) it should show the device. Windowsįor Windows, you can also use a program like PuTTY or CoolTerm. In Particle Workbench (VS Code), open the command palette (Command-Shift-P on the Mac, Ctrl-Shift-P on Windows and Linux) and select Particle: Serial Monitor. Press Enter to Copy to the clipboard (also in the Edit menu).Drag a selection around the text you want to copy.It's also available if you click on the icon in the upper left corner of the window in the Edit menu. The Windows Command Prompt has an unusual method of copying to the clipboard: This is helpful because if the device resets (including after a firmware update) One particularly useful command line option is the -follow option which will reconnect to the Particleĭevice if it disconnects. For Mac or Linux, open a Terminal window. On Windows, open a Command Prompt window to use the particle serial monitor command. Opening serial monitor for com port: "/dev/cu.usbmodemFD1161" Still, it's quick and easy, and very handy. Note that the CLI only reads serial messages, it is strictly a serial monitor, and you can't type things to the Photon/Electron. Using a terminal program Particle CLIĪ common way to view debug serial messages is the Particle CLI. Apple iOS (iPhone and iPad)ĭevices do not support USB OTG. Like a USB host, even though it's normally a USB device. Some Android phones can plug directly into a Particle device by USBīy using a USB OTG ("on the go") adapter, which allows your phone to behave mostly Gen 2 Wi-Fiĭevices (Photon, P1) have a limited ability to communicate directly over Wi-Fi for Gen 3 Particle devices can connect by Bluetooth LE (BLE) to your phone. Of communicating with a mobile app is over the Internet through the Particle cloud. You generally cannot connect your phone to a Particle device by USB. They are other, easier ways to add serial ports. ![]() You also cannot connect something like a USB RS232 adapter, though They cannot be used as a USB host, so you cannot plug a USB keyboard into a Photon Particle devices are a USB device, intended to connect to a computer. Use the network type they are designed for, such as Wi-Fi or cellular. It's not possible for devices to communicate with the Internet over USB they must It's also possible to update your user firmware and Device OS over USB. ![]() While Particle Devices typically communicate using the Particle Cloud and the Internet,įor debugging code and troubleshooting, it's often common to use a USB connection to yourĬomputer or laptop.
