Re: using HDMI LCD and desktop

Thanks a lot for all the good info...By the way does using the VNC mode slow down/hog the pi (compared to running headless or normal)? My app is running the PI pretty hard, so not sure how much impact VNC has.

Re: using HDMI LCD and desktop

Thanks for the tip about VNC...had no idea it was out there..would the headless mode accomplish the same thing? As I mentioned, I don't even want to show the desktop on the little HDMI LCD, I just want my graphs to appear on it (perhaps that is not possible). I just want to see the PI desktop on my ...

using HDMI LCD and desktop

Hello: I have the pi3 & latest Raspbian running fine. Recently I added a 5 inch hdmi bolt-on display with 800x600 res & edited the config file so it boots and works fine...I only want to use it to display some graphs & charts of incoming pi sensor readings. However, the screen is MUCH too small to u...

Re: control panels

Thanks for the link, I am looking for more of these. I prefer the user screen not to show any "boot up" text, just the running app (like someone just plugged in & turned on their new washing machine), but this is close. Here is one I found (thanks to your link) https://learn.adafruit.com/piphone-a-r...

control panels

I haven't found many examples of anyone actually using the rpi with a small touch display user interface to control anything (say make a digital thermostat, or front door access lock, control your garage door, adjustable countdown timer, etc ...)...if you know of some links, I'd like to see them (as...

silly lcd question

I'm thinking about adding a touch color LCD to my PI to show messages in various fonts & colors & simple line shapes. Up til now I've just been programming using my HDMI monitor to write a few I/O apps (blink some leds, read switches, etc). HOWEVER, all of the examples I've seen regarding adding on ...

Re: installing bluez 5.25

I figured it out.. first, I was in the wrong directory...then, I got permission denied...then I added sudo...then it finally worked!

do:
cd bluez-5.23
sudo cp attrib/gatttool /usr/local/bin

now gatttool is "present" & runs

Re: installing bluez 5.25

I did a sudo find / -name gatttool & it came up with:

/home/pi/bluez-5.23/attrib/gatttool

so it is in there. How do you get it situated so the gatttool command works (any gatttool commands return with "command not found")

without gatttool operational, I can't investigate much

bluez command set

Hello:

Where is the information detailing the various bluez "commands"? For example, hcitool has a command lecc that accepts various optional parameters (such as -random)...where are these described & explained? what do they do?

I'm looking for a link to a document or website with the details

installing bluez 5.25

What are the step required to install the latest version of bluez (5.25)? I'm just getting started with doing so & seems rather cryptic. I saw somewhere it requires D-Bus-1.8.12, GLib-2.42.1, and libical-1.0.1. However, even with an rpi update, my versions of these seem earlier (1.6.8, for dbus)
