Comment (by ox.to.a.cart):

 The good news is that the latest version of Lantern (which internally is
 called flashlight) doesn't require Java, it's built in Go.  The easiest
 thing to do is probably to compile it on a Raspberry Pi and then
 distribute it in binary form.

 Here are some useful instructions.

 https://github.com/golang/go/wiki/GoArm#raspberry-pi

 I do need to do a little work to make sure it'll run happily from the
 command-line, which I've captured in a ticket -
 https://github.com/getlantern/lantern/issues/2288

 In answer to the open questions:

 1. You can tell that flashlight is running using netcat.  Assuming it's
 running at localhost:8787, you can use "nc -vz localhost 8787"

 2. flashlight logs debug to stderr and errors to stdout.  If there are
 connectivity issues, they will show up in here.  I'm happy to tweak the
 log output to make it easier for ooniprobe to diagnose what's going on.
 If there are specific  types of conditions that you're looking for, please
 let me know.

 Thanks so much for offering to integrate Lantern into your test suite!

 us to understand why and how it is being blocked
