This article is related to an older version of the Red Pitaya OS. With the latest image Red Pitaya has improved the configuration. The step-by-step instructions can be found here:

Since a few days I’m a proud owner of a Red Pitaya (Homepage). Getting this neat little device up and running is relatively straight forward (extract the ZIP-file containing the OS on a microSD-card, insert the card into the Red Pitaya and power it on).


Using the Red Pitaya with an USB WLAN dongle is not as intuitive as the previous mentioned setup. Below I’ve detailed the steps required to correctly setup the device as a WLAN client, which I think is the most common used setup.

As recommended in the Red Pitaya user manual I’m using a Edmiax EW-7811Un WIFI dongle.

Note: When working via SSH the content of the microSD-card (as shown on the desktop computer) is available under /opt.

  1. Insert the microSD-card into the computer (or connect to the device using SSH)
  2. Open /etc/network/wpa_suplicant.conf (when directly accessing the microSD-card) or /opt/etc/network/wpa_supplicant.conf (when working over SSH) in your favourite editor and enter the WLAN configuration details (esp. SSID and PSK).For a WLAN with WPA2 this looks like:
  3. Enable WLAN by changing the wlan0 entry in the file /etc/network/inferface (microSD-card) or /opt/etc/network/interface (SSH) to
  4. By default the Red Pitaya is configured as WLAN accesspoint. To change this edit /etc/network/config (microSD-card) or /opt/etc/network/config (SSH) and change the WIFI entry as follows:
  5. Remove the microSD-card from the computer, insert it into the Red Pitaya, power it up and wait a few seconds to let it connect to the configured WLAN access point
