The Electron has two additional UART serial ports that you can use, Serial4 and Serial5. ItвЂ™s a complicated enough topic that it has its own tutorial. Using it requires soldering and disabling the status LED, which will make troubleshooting your device very difficult. The catch is that Serial2 is on the same pins as the RGB status LED. вЂ The Photon actually has two and the Electron four UART serial ports. This is always the case, even if you connect two Photons by serial. When you connect a Photon another device, say an Arduino, the RX pin on the Photon always gets connected to the TX pin of the Arduino and vice versa.

TX means serial data transmitted from the device.

RX means serial data received into the device.

The Photon has one вЂ and the Electron has three UART serial ports.ДЄll of the devices have the Serial1 object, the main UART serial port, on the RX and TX pins. When connecting to an actual serial device, youвЂ™ll be using one of the UART hardware serial ports.

28800 Listening mode (blinking dark blue).

(The device name, cu.usbmodemFD1141 in this example, may be different on your computer.)

You can also trigger it by making a USB Serial connection at a specific baud rate.ДЇor example, on the Mac you can use this command to enter DFU mode: stty -f /dev/cu.usbmodemFD1141 14400 Normally you press buttons to enter listening or DFU mode on the Photon or Electron. The commands other then the last two Wi-Fi related commands are also available on the Electron. You can also get into listening mode by holding down SETUP for about 3 seconds until the status LED blinks blue. Listening mode is the default when you plug in a Photon the first time.

m - Print MAC Address for the Wi-Fi adapter.

L - Safe listen mode (does not run user code concurrently with listening mode).

i - Prints the device ID (24 character hexadecimal string).

Each of these commands only requires that you type the command letter (case-sensitive): If the Photon is in listening mode (blinking dark blue), configuration can also be done using the USB Serial port. Tap yes and you should see a screen in the picture above.

Open the serial monitor app and it should ask if you want to connect to the device.

Install the вЂњAndroid USB Serial Monitor LiteвЂќ application from the Google Play store.Д¬onnect the device to your phone using a USB cable and a USB OTG adapter.

If your Android phone supports USB OTG (вЂњon the goвЂќ) and you have an OTG adapter cable, you may be able to use it for debugging serial! One caveat is that your phone probably wonвЂ™t power up a Photon, so this will probably only work if you have an external power source, like an Electron or Photon with a battery. 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/ttyACM0 It should return something like /dev/ttyACM0. Linux - using screenДЇind the serial port that is being used using the Terminal program command line: ls /dev/ttyACM* Then issue the command: screen /dev/cu.usbmodemFD1161 It should return something like /dev/cu.usbmodemFD1161. Mac - using screenДЇind the serial port that is being used using the Terminal program command line: ls /dev/cu.usb* This is the configuration screen for PuTTY:Д¬lick Serial (1) then enter the COM port number (2) then click Open (3). Make sure you have the correct port select and click Connect. Select Show Serial Monitor in the Particle menu if the Serial Monitor is not showing. Opening serial monitor for com port: '/dev/cu.usbmodemFD1161' Still, itвЂ™s quick and easy, and very handy. Note that the CLI only reads serial messages, it is strictly a serial monitor, and you canвЂ™t type things to the Photon/Electron. Particle CLIДЄ common way to view debug serial messages is the ( ). The Serial.printlnf prints a formatted string to the debugging USB serial. Sometimes youвЂ™ll see Serial.begin(115200) but it really runs at the same fast speed regardless. When youвЂ™re using the USB serial, the value doesnвЂ™t actually matter. The Serial.begin(9600) call initializes the serial port.

Serial.printlnf('testing %d', ++counter) Often this is used for debugging messages. The USB serial provides a way for the Photon/Electron to send data to the computer across the USB connection.
