Re: RPi Display Goes Black at Boot

So, last night I hit on the rather obvious idea of just writing a new card and seeing if the screen comes on and works. It does. So, it is not a hardware issue. I will mark this on as "solved but don't know why".

Solved but don't know why: RPi Display Goes Black at Boot

I have an RPi 3B and have had it powering an RPi display for a few years. I recently reimaged my card using dd from another Pi+display combo that was working perfectly and tried to boot the system with both the source and the reimaged card. The display turns on when I boot the pi, shows the for red ...

Re: Can't see minidlna server through RPi access point

Crud. My bad. I mistyped. Your intuition is correct. Mobile devices are in .6.2 to .6.100 range.

I followed a guide I found years ago. I will try to dig it up later. The APs are running latest Stretch version and fully updated.

Re: Can't see minidlna server through RPi access point

No, my version is not too old. Is there something better than minidlna I could use? Basically, I just have a bunch of audio and video files on a raspberry pi server and I want to dish them out to mobile VLC clients on the network. I am not married to this solution of using minidlna. I am not clear o...

Re: Sharing data between python scripts through a LAN

IT WORKS! IT WORKS! This is the coolest thing I have done on my Pi's. I wish I had figured this out years ago. I have about 12 Pi's in my house doing lots of different jobs and the one thing I have struggled with the most is getting them to coordinate with each other. I have a lot of code to sort th...

Re: Sharing data between python scripts through a LAN

Ok, so I got it to work by putting 'localhost' in the one machine (broker). In the other one, I left the IP address of the broker and it worked. Putting localhost in both, does not work. This is cool stuff. I will just set one Pi on my network as the broker and have all other machines reference to t...

Re: Sharing data between python scripts through a LAN

Oh, that is interesting. I thought the addresses had to be different. Should they be the address of the publisher computer or the subscriber? They are not the actual addresses, but are different in my code. I did do the stuff above (command line stuff) so I know it is working fine - just not in my c...

Re: Sharing data between python scripts through a LAN

Ran through your mini tutorial tonight @asandford and it WORKS. So cool. Replaced "localhost" with an ip address on my lan and can send messages between Pi's too. So cool.

Thanks!

Re: Sharing data between python scripts through a LAN

Oh, this is cool stuff. Thanks for all the help folks. It is going to take me a few weeks to start playing around with this in my spare time. This is definitely what I need for my little home control IOT project.

I'll report back on progress.

In the meantime, I tried asandford's recommendation. I did this: sudo apt-get install mosquitto sudo pip install paho-mqtt And these two things installed no probs. I did some reading here: https://pypi.python.org/pypi/paho-mqtt/1.3.0 but quickly got lost. Have not yet found a tutorial for dummies on...
