To learn how to connect the external clock to STEMlab 125-14 & STEMlab 125-14-Z7020 click here, and to SDRlab 122-16 click here.

  1. Connect to your Red Pitaya over SSH.
  2. Make sure that you can ping the google.com website:

The simplest answer is just make sure that your Red Pitaya and your PC/tablet/smartphone are connected to the same router or your smartphone hotspot.

In order to test this you can use a PC that is connected to the same local network as your Red Pitaya and try the following:

  1. Open 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 the arp -a command to list all devices in your local area network and try to find your Red Pitaya MAC address on the list.

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

  3. Note: If you have established a wireless connection, then you should check the MAC address of your wireless USB dongle. The MAC address will usually be written on the USB dongle.

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

    If your Red Pitaya is not listed on the list of your local network devices in the local network, then it is necessary to check that your Red Pitaya is connected to your local network.

A Red Pitaya URL is rp-xxxxxx.local, where xxxxxx must be replaced with the last six characters of the MAC address that is written on the sticker.

If the RP MAC address is 00:26:33:F1:13:D5, then the last six characters are F113D5 and the URL is rp-f113d5.local.

  1. Connect your Red Pitaya to your PC over the serial console using the following steps.
  2. Type “ip a” and hit enter to check the status of your ethernet connection to your Red Pitaya.
    1. If you have connected to your Red Pitaya over aa wireless connection, you should check the status of the wlan0
    2. If you have connected to your Red Pitaya over cable connection, you should check the status of the eth0
  3. Type your Red Pitaya IP into your web browser to see if you can connect to it.

1.       First check the LEDs:

  1. If the green LED is not ON or is blinking then it something is probably wrong with the power supply or maybe the USB cable. Make sure that:
    1. you have plugged the USB cable into the right USB connector on the Red Pitaya
    2. your power supply is 5V/2A
  • if there are no problems with the above, then replace the USB cable and USB power supply
  1. If the green LED is ON, but the blue LED is OFF, then there is an error while loading the Red Pitaya system from the SD card. Make sure that:
    1. you have properly inserted the Red Pitaya SD card and that it has properly installed the Red Pitaya OS. (Note that Red Pitayas come with a pre-installed OS on SD cards. However, SD cards can get corrupted, and if this is the case then please follow these instructions to properly re-install the Red Pitaya OS to the SD card)
    2. try to use another SD card
  2. If the green and blue LEDs are ON, but the red and orange LEDs are not blinking, then notes that the red LED indicates the CPU’s heartbeat, while the orange LED indicates access to the SD card. Notice that these two LEDs always start blinking 10 seconds after the green and blue LEDs are turned ON.
  1. Make sure your Red Pitaya and computer are connected to same local network.
  2. If you are a Windows user, make sure you have installed Bonjour Print Services.
  1. Make sure your Red Pitaya has access to the internet. How?
  2. Force a refresh of the Red Pitaya application page. How?

If the wireless connection with your Red Pitaya works very slowly and all the applications seem unresponsive and are not running smoothly, please check the following:

  • the Wi-Fi signal strength on your PC/tablet/smartphone
  • the Wi-Fi signal strength of your Red Pitaya
    1. Connect to your Red Pitaya via the SSH connection. SSH connection
    2. Enter the cat /proc/net/wireless command in order to get information about the link quality and signal strength.

The link quality measures the number of packet errors that occur. The lower the number of packet errors, the higher this will be. Link quality goes from 0-100%.

The level or signal strength is a simple measure of the amplitude of the signal that is received. The closer you are to the access point, the higher this will be.

Note: For full performance the wired connection is preferred.

Please note that not all Wi-Fi dongles are compatible with your Red Pitaya, and the full list of those that are can be found in the documentation: Supported USB Wi-Fi adapters

Red Pitaya can be calibrated using the calibration tool.

Please check if the ad blocker has been disabled on your browser and also check your proxy settings. The proxy settings should not be required for local connection to a Red Pitaya unit.

  1. One possible cause could be a corrupted card, and the recommended solution is a manual OS re-write: Prepare SD card

No, the hardware is identical, the only difference is that the later was sent to a certification lab and the appropriate measurements were made.

We recommend testing the system on a different computer, checking the state of the Ethernet cables and power supply, proxy settings, and re-writing the OS.

If the RP MAC address is 00:26:33:F1:13:D5, then the last six characters are F113D5 and the URL is rp-f113d5.local.
