Error with examples ln1 and ln2

[larry104]

Hi there,

when running the ln1/2 examples I get the following error after a few seconds:
`2020/04/21 11:22:17 Listening...

ERROR: Expected ACK, got I
`
Any idea where this is coming from? I have the etherdream2 with the latest firmware r310-4288429.

I haven't tried it with ether dream 2. I just updated master with some extended protocol debugging info in place of that error message. Want to try again?

This is what I get now ...

Laser was not tuned on ... here ln1 - that seems to run now - a static cube

ln2 errors out.

I'm not really sure. You might need to do some protocol debugging. You can get a little more info by running ln2 with -debug and there are protocol docs here. https://ether-dream.com/protocol.html

This project should be considered semi-abandoned and for mostly educational purposes.

ok then - I will play with it. Thanks!
