Re: How use phone bluetooth to reboot Zero?

Thanks again Douglas6! I'll have to study what you've mentioned and also https://hacks.mozilla.org/2017/02/headless-raspberry-pi-configuration-over-bluetooth/ . Just a little note: I'm not wanting the ZeroW to automatically pair with a device (like a speaker), but just to allow later pairing with a ...

Re: How use phone bluetooth to reboot Zero?

To be discoverable, the Pi needs to be put into discoverable mode.
Is there any way to do that automatically upon first bootup? I'm trying to see if there is a simple way to bring up a ZeroW without connecting a HDMI monitor and keyboard.

Re: How use phone bluetooth to reboot Zero?

Thanks for all of the previous suggestions. HermannSW: My ZeroW is already connected to the building WiFi so I just want to use bluetooth to adjust settings or do simple commands. I'm able to use my phone to do that with the bluetooth instructions already on the http://controlpascal.com/self-hosted....

Can I hijack my own thread from last month? I'd like to convert my entire project (on page linked in my previous message) to Python.

How use phone bluetooth to reboot Zero?

I've got several Zeros that send text and emails every 3 hours for temperature and power detection. I'd like to be able to use my Android phone to reboot them about once a week (or change settings later). I'm thinking of using APDE on the phone (see bottom of this page): http://controlpascal.com/sel...

Re: Best first language choice

I think that for learning, Javascript is the easiest way to start and get results very quickly. You can run a hello world with absolutely no boilerplate, just one line of code by going here (http://jsfiddle.net) and writing document.write("hello world"); You can also run it on almost ANY machine an...

Re: Free Pascal does not run.

Support for the hard float ABI in freepascal was added by a patch I wrote which is not in upstream 2.6.0 so if you are using a 2.6.0 build that is not dervived from the debian package you almost certainly don't have the right ABI which will cause problems with you try to link with C code. My curren...

Re: Free Pascal does not run.

pbreneman I tried your EasyfpGUI-fpc-2.6.0.arm-linux-052512. At least the helloworld and memotest seem to compile and run OK. I notice the build scripts use a ppcarm binary supplied in the zip. How can I be sure this is generating the correct floating point instructions and using the right ABI? Tha...

I just managed to get Free Pascal 2.6.0 working on Raspian from it's sorceforge down load at: http://sourceforge.net/projects/freepascal/files/Linux/2.6.0/ ... I suspect this does not use optimal floating point options off the bat. If that works then some of the ARM Linux zips on my educational pro...

Hi Lucretia, I'd like to learn more about Ada. Is there any way to create minimal packages that contain the minimal amount of files to compile a program?

Re: Simple interfaces without xwindows

With Free Pascal you can do things similar to what you did with Turbo Pascal. I have a number of minimal distributions of Free Pascal that make it *very* easy to try things. See this new message:
