Re: Installing Java ME in Raspberry Pi 3 Model B+

Ah their installation guide is based on Wheezy not Stretch, so may not work.
Also they say you have to run

Code: Select all

pi@raspberry ~/bin $ fix_permission.sh
before running any of their script demos

Maybe have a look at Node-RED on the pi to start with.

Re: Compile time-lapse from terminal with "date_time.jpg" formatet files

Assuming your file names only change the last four digits e.g 2019-01-30_0909.jpg, 2019-01-30_0915.jpg, etc. Then replace it with 2019-01-30_%04d.jpg

Have you got two resistors in the correct place to bring the ECHO down from 5 Volts to 3.3 Volts?
Also, post a picture of your wiring so we can look at it.

Re: Remote GPIO Script/Recipe

To read values from a temperature sensor (e.g. DS18B20) into openhab2, what I do is configure openhab2 to use an mqtt server (mqtt broker) and display items from that (i.e. temperatures) in HABpanel. The pi with the temperature sensor publishes the values to the mqtt server every five minutes.

I am not following you. Maybe you have a broadband connection to a modem/router (with wifi) in your house? That should be giving IP addresses to the various PCs/phones etc. in your house, probably in the range 192.168.1.2 to 192.168.1.254. If you install "fing" on your phone, what does it report (ip...

Re: set times for slideshow/screensaver

What happens if you log in to the pi, open a Terminal window, change to the directory your photos are in, and use the fbi command :

Code: Select all

sudo fbi -T 2 -t 5 -a *
On my pi that gives a slideshow of the photos 5 seconds for each.

Try this basic one, which just has a counter in front of the filename (defined as a global), so you get 1video.h264, 2video.h264 etc. I convert the count to a string and include it in the filename.

Maybe use mqtt on the arduino to publish the data as a topic and mqtt on the pi to subscribe (listen out for) to that topic whenever it happens.

From their website, the "FiOS Router" has 4 Ethernet ports and DHCP. Are you sure they are working to give out IP addresses on Ethernet cable to any attached device - PC, pi, etc? It would be very unusual if not. Can you log in to that router and see what devices it thinks are attached via Ethernet ...
