google permissions

My AIY voice kit has been working but today, when I ask a question, the response is that some basic settings need my permissions, and the details are on the Google Home Ap. I have installed the Google Home Ap on a tablet but cannot see what to do next. Has anyone solved this?

Re: Python bluetooth

Thanks topguy, bash -c solves the problem. It does need single quotes round the python2 command.

Python bluetooth

I am trying to run a python script which uses the bluetooth library from a shell command in action.py of the voice-recogniser. Because the voice-recognizer runs in a virtual environment, the bluetooth library (python2) is not found. The script works when run from the command line outside the virtual...

Re: Battery power

Thanks for feedback on the amount of power, but I am wondering about powering via the Voice Hat. Is there anything more to do than just connecting 5v to the unused solder pads?

I would like to use battery power. Would it be simply a USB power pack connected to the 5volt connectors on the Voice Hat?

Re: Location within a garden

Has anyone tried using a Sense Hat to track location? If I always put my wheelbarrow away in the same place, and so begin my travels at a known location, how long would it be before the tracking was more than a metre out? Is it worth trying?

Location within a garden

To implement IoT in a gardening context it would be useful to be able to locate an activity (such as planting seeds) accurate to within a metre. As basic GPS is not accurate enough, is there a way of finding position (electronically) relative to some fixed reference points around the garden?

It is useful to have several desktops but when using the gui to set them up the extra desktops are lost after a reboot. Is there config file or command-line function to set these up, as in Ubuntu?

Re: esp8266 and minicom

Cntrl-J after 'Enter' in minicom sends the cr/lf required by esp8266 to complete each command. The 'Add Linefeed' feature of minicom just adds LF to the response, not the request.

Is there a way to search the forum avoiding the normal search restrictions? For example, I want to search for node.js. The dot is ignored, then the js is too short and node has hundreds of references. Putting it in quotes makes no difference. Any ideas?

I have just bought a CM15pro and installed Mochad software but cannot switch X10 devices, including an AM12. It does log other X10 activity, such as from SM10E, so it is reading X10 messages. Has anyone found a need for any special setup for the Pi beyond the basic install instructions for Mochad?
