External pc reset button disk led3/17/2023 Wait for the LED to start flashing yellow (it will flash magenta first)ĭFU mode requires device drivers under Windows.This mode triggers the on-board bootloader that accepts firmware binary files via dfu-util If you wish to program your device with a custom firmware via USB, you'll need to use this mode. You can also use the particle usb safe-mode command to enter safe mode. The device will itself automatically enter safe mode if there is no application code flashed to the device or when the application is not valid. If you're unable to connect to the cloud, you won't actually end up with breathing magenta, but execution of application firmware will still be blocked - so you are in a "sort-of safe mode" (e.g. Wait for the LED to start blinking magentaīefore entering safe mode, the device will proceed through the normal steps of connecting to the cloud blinking green, blinking cyan, and fast blinking cyan.Release only the RESET button, while holding down the SETUP button.The device indicates that it is in Safe Mode with the LED breathing magenta. Runs the Device OS but doesn't execute any application code, which can be useful if the application code contains bugs that stop the device from connecting to the cloud. You loaded onto your device, you can set your device to Safe Mode. This mode is one of the most useful forĭevelopment or for troubleshooting. Safe mode, breathing magenta (red and blue at the same time), connects the device to the cloud, but does not run any application firmware. Put the device in listening mode (blinking dark blue) by holding down the SETUP button, then use the Particle CLI command particle serial mac. If the Wi-Fi network restricts access to known device Ethernet MAC addresses, you'll need to determine the MAC address and give it to the network administrator. You will need to flash a program by USB to set the IP address. If your Wi-Fi network does not support DHCP, and only uses static IP addresses, it is possible, though somewhat difficult, to set up a device. If you get fast blinking green, especially in classroom and hack-a-thon type situations, it is possible that your network has run out of DHCP IP addresses. However it may be possible to connect your device with some difficulty by following the WEP configuration instructions. If your router uses WEP encryption, you should upgrade your router to something more secure.If your Wi-Fi network uses 802.11n only mode (does not support 802.11b, 802.11g, or a combination of b, g, and n), it's not currently possible to connect a Photon or P1 to the network if the device is running Device OS 0.7.0 or later. The Wi-Fi radio is only compatible with 2.4 GHz networks. If your Wi-Fi network uses 5 GHz only, instead of the more common 2.4 GHz, the device cannot be used. This is the case in some hotels and public Wi-Fi networks and is often referred to as Captive Portal. If you are using a network that takes you to a web page where you need to either sign in or agree to terms and service when you first connect, using the device directly will be difficult or impossible. If you require both a username and a password, or see a mention of 802.1(x), or RADIUS you're using WPA2 Enterprise. If you are using a corporate or school network that uses WPA2 Enterprise, you will need to follow special setup instructions. If you are unable to get past blinking green, here are a few known working situations that the device is not compatible with:
