I have configured several Kiwis for wifi access by attaching an inexpensive router configured as a Wifi client to the ethernet port of the Kiwi. This $25 TP Link has worked well for me: https://smile.amazon.com/TP-Link-Wireless-Portable-Travel-Router/dp/B00TQEX8BO/ref=sr_1_14?keywords=tplink+wifi+router&qid=1548188019&sr=8-14 In principle one could enable the internal BB Wifi or attach a USB wifi adapter, but I am reluctant to fiddle with the Kiwi's OS.

  • 'Mobile' operation without a network?

    When I connect the microUSB port of the the Kiwi to a USB port of a Raspberry Pi, the Pi sees a new ethernet interface appear on LAN 192.168.7.0/30. The Kiwi assigns itself 192.168.7.2, but I forget if it acts as a DHCP server to the Pi. So on the Pi you may need to assign that new USB 'dongle' the address 192.168.7.1.

    After that the Kiwi UI can be accessed at 192.168.7.2

  • KPH Kiwis down?

    The Park Service has denied us volunteers access to the KPH facility since the start of Covid last spring. While that is annoying I am sympathetic to their situation. If they were to grant exceptions to one set of citizens, then other would want the same privileges.

    As soon as I am allowed, I will go out there and restore operation. Look for KPH WSPR spots on http://jimlill.com/today_int.html to learn when that happens

  • IP connection to Kiwi through Kiwi's USB interface

    SOLVED

    I carefully read the "Using a USB network connection for initial Beagle access" section of the user manual but could access the Kiwi from a Win10 PC or from a Raspberry Pi

    On the Kiwi, 'ifconfig' command lists usb0 with IP address 192.168.7.2 and MAC 40:bd:32:e5:40:02, and usb1 with IP 192.168.6.2 and MAC 1c:ba:8c:a2:ed:73

    On the PC, when I plug in the USB cable from the Kiwi, a new DHCP network interface appears but that interface gets no IP address. The beaglebone documentation describes a drive which should appear as well, but Win 10 shows only this additional network interface with MAC 40:bd:32:e5:40:01. That MAC differs by 1 from the usb0 MAC on the Kiwi, so the PC and Kiwi are communicating.

    On the Pi, when I plug in the USB cable from the Kiwi two new interfaces appear: eth2 with the same MAC 40:bd:32:e5:40:01 which is assigned to the PC interface, and eth1 with MAC 1c:ba:8c:a2:ed:72, but those Pi interfaces give themselves self-assigned IP address. Running 'tcpdump -i eth1' on the Pi I can see it sending out DHCP request packets but getting no response, so I infer that the BeagleBone is not responding to DHCP on those usb0/1 ports.

    However, by configuring the Pi's eth1 and eth2 with static addresses I was able to gain complete ssh and GUI access to the Kiwi at both 192.168.6.2 and 192.168.7.2.

    To manually configure those IP address on a Pi, add these four lines to /etc/dhcpcd.conf

    pi@Berk-Pi4b-90:~ $ tail -4 /etc/dhcpcd.conf interface eth1 static ip_address=192.168.6.1/30 interface eth2 static ip_address=192.168.7.1/30 pi@Berk-Pi4b-90:~ $

    I don't have a second Kiwi here to test a two Kiwi system, but it seems I could modify the usb0 address 192.168.7.2 in /etc/network/interfaces to 192.168.8.2 and configure the Pi to add a corresponding ethX with 192.168.8.1

  • WSPR internal kiwi decoder

    I could imagine installing WD on a BBAI machine and dedicate a core to run it.
    But synchronizing Kiwi and WD code upgrades would be a mess.
    For example, just this week I was able to upgrade 20+ WD sites to use the wsprd in WSJT-x 2.2.1 which produces up to 6% more spots from the same antenna+Kiwi.
    Also, many installations use 2 or more antenna+Kiwis, and embedding WD in one Kiwi would result in an asymmetric set of Kiwis.

    So it is far better to run WD on a $35 Pi 3b (or better yet a 2/4Gb Pi 4) which can support 30+ channels of Kiwi bands.
