Red Pitaya internet connection Troubleshooting

Problems connecting to RP?

1. First, check the LEDs:
1. If the green LED is not ON or is blinking: It seems like something is wrong with the power supply or maybe the USB cable. Make sure that:
• You have plugged the USB cable into the right USB connector on the Red Pitaya.
• Your power supply is 5V/2A.
• Try to replace the USB cable and the USB power supply.
2. If the green LED is turned ON but the blue LED is turned OFF: There is an error while loading the Red Pitaya system from the SD card. Make sure that:
• You have correctly inserted the Red Pitaya SD card and the Red Pitaya OS is installed (Red Pitayas come with a pre-installed OS on SD cards. However, SD cards might get corrupted. In such cases, follow the instructions on how to prepare the SD card to properly re-install the Red Pitaya OS).
• Try using another SD card.
3. If both the green and blue LEDs are ON, but the red and orange LEDs are not blinking: The red LED indicates CPU heartbeat, while the orange LED indicates access to the SD card. These two LEDs should start blinking 10 seconds after the green and blue LEDs are turned on.

2. Make sure your Red Pitaya and computer are both connected to the same local network.

3. If you are a Windows user, please see the note below.

• Windows 7/8 users should install Bonjour Print Services; otherwise, access to .local addresses will not work.

• Windows 10 already supports mDNS and DNS-SD, so no additional software is required.

How can I make sure that my Red Pitaya has access to the internet?

1. Connect to your Red Pitaya over SSH.

2. Ensure you can ping google.com with the following command:

root@rp-f03dee:~# ping -c 4 google.com
PING google.com (216.58.212.142) 56(84) bytes of data.

How can I make sure that Red Pitaya is connected to the same network as my computer/tablet/smartphone?

1. Open the terminal window:
• Windows: Go to RUN, type in cmd, and press Enter.
• Linux: Click on the application button, type in Terminal, and press Enter.
• macOS: Hit Cmd + Space, type in Terminal, and press Enter.

2. Enter arp -a to get a list of all devices in your local area network and try to find your Red Pitaya MAC address on the list:

arp -a
? (192.168.178.117) at 00:08:aa:bb:cc:dd [ether] on eth0
? (192.168.178.118) at 00:26:32:f0:3d:ee [ether] on eth0
? (192.168.178.105) at e8:01:23:45:67:8a [ether] on eth0

Note: If you have a cable connection, then your MAC address is written on your Red Pitaya LAN connector.



Note: If you have established a wireless connection, then you should check the MAC address of your wireless USB dongle. The MAC addresses are typically written on the USB dongles.

3. Type your Red Pitaya IP into your web browser and connect to it.
