Sorry to bother again.

Is it normal that I get this with "sudo service check_beacon_presence status"

● check_beacon_presence.service - LSB: This daemon manages the bluetooth low energy device detector : check_beacon_presence
   Loaded: loaded (/etc/init.d/check_beacon_presence)
   Active: inactive (dead)

If I submit then a "sudo service check_beacon_presence start"
I get

Code: Select all

The script is working great, don't understand where I am doling wrong on the startup phase.

not sudo service ...
the right command :

Code: Select all

sudo /etc/init.d/check_beacon_presence status

Posted: **Sunday 08 May 2016 15:50**

Ops, sorry I didn't noticed also in previous post!!

So now I get

Code: Select all

   Loaded: loaded (/etc/init.d/check_beacon_presence)
   Active: active (exited) since dom 2016-05-08 15:13:32 CEST; 27s ago

Is it correct?

Thanks again.

sorry to sound like such a total noob

But I have my hardware today (thank you amazon prime) but how do I interogate my NUT to get the info needed for the python script?

Many thanks

Sean

Just put the info needed in the check_beacon_presence.py
You can get your nut Mac address from any Ble app, in my case for Android.
Then put Mac address and domoticz idx of a new User variable in string format.
And follow the instruction some post before to launch the script or to launch during boot phase

You only need the MAC Adresse of your beacon. And to get it, just run the python script once (with the log enable). The MAC Adresse of your bluetooth device that are broadcasting around you will be displayed.

Hi guys,

Thanks for the earlier help

I have it all installed but I'm struggling now with getting the daemon to run.

Code: Select all

pi@bluetooth1 ~ $ sudo /etc/init.d/check_beacon_presence start
[ ok ] Starting check_beacon_presence:.
pi@bluetooth1 ~ $ sudo /etc/init.d/check_beacon_presence status
[FAIL] check_beacon_presence is not running ... failed!

and the /var/log/check_beacon_presence.log isn't being generated so I can't see why.

Code: Select all

# choose between DEBUG (log every information) or CRITICAL (almost no log)
#logLevel=logging.DEBUG
logLevel=logging.CRITICAL

logOutFilename='/var/log/check_beacon_presence.log'       # comment this line to console output

I've tried all the above "fixes" but can't see where I'm going wrong.

This part confuses me a little too,

Code: Select all

# Configure your Beacon here : 
# [Name,MacAddress,Timeout,0,idx,mode]
# Name : same as the uservariable in Domoticz
# Timeout is in secondes the elapsed time  without a detetion for switching the beacon AWAY. Ie :if your beacon emits every 3 to 8 seondes, a timeout of 15 secondes seems good.
# 0 : used by the script (will keep the time of the last broadcast) 
# idx of the uservariable in Domoticz for this beacon
# mode : 0 for 1 update per status change / 1 continuous updating

TAG_DATA = [  
           ["Foo_Tag","xx:xx:xx:xx:xx:xx",15,0,1]
           ]

shouldn't it be

Code: Select all

["Foo_Tag","xx:xx:xx:xx:xx:xx",15,0,1,0]

Many thanks

Sean

What is the DAEMON_USER in /etc/init.d/check_beacon_presence ?
It was pi, that I changed to root

To see log, uncomment the .DEBUG one and comment the .CRITICAL

I didn't noticed the last parameter, I don't have it, and it works (not the service part for me, just launching with sudo pyhton check_beacon_presence.py).

Posted: **Monday 09 May 2016 13:00**

Hi Woody,
I'm slowly catching up,

I found that I had a few python "bits n bobs" missing... which REALLY didn't help

Sooo...

I cannot get the daemon to run manually or as a service as either user (pi/root) but I can get

Code: Select all

sudo python /usr/local/bin/check_beacon_presence.py

to run now
In the log it says my NUT is away... in reality it's 1cm away

and on checking my dongle with

Code: Select all

hcitool scan

I see my phone but no nut. I added my phone to the python script but that shows as away too

dear oh dear

Thanks for the support so far though

Sean

PS is the 65 in woody4165 a year? are you a fellow 65er?

Posted: **Monday 09 May 2016 13:47**

thanks for the wonderful replies guys.

Posted: **Monday 09 May 2016 13:58**

Yeah, I'm a 65er "guy"...

Have you tried with an app like "BLE Scanner" to check if your Nut is seen (Nut 2 or 3)?

I got my MAC address from there (didn't know the script can do this!) and just filled out the py script

Code: Select all

["MyTag","xx:xx:xx:xx:xx:xx",15,0,yy]

The last tag you have does not need the comma at the end, if you have more than one.

Posted: **Monday 09 May 2016 14:46**

ok,
if I run

Code: Select all

sudo python /usr/local/bin/check_beacon_presence.py &

after manual starting my BLE dongle, user variable for the NUT is switching between home and away... so I just need it to start on boot and I'm super-happy!

Could I have a peep at the script you wrote Woody? I assume it turns on a virtual/dummy switch when the variable says "HOME"

Cheers buddy

Sean

New BLE idea: I just got my TI SensorTag (29 US$. read more: http://www.ti.com/ww/en/wireless_connec ... =sensortag ) which has 9 embedded sensors and provides via bluetooth it's data.
As first thought was to get it as a personal Tag, BUT now I have a better project: Monitor my refrigarator! I get temperature, moisture, motion data (if someone opens the door of fridge) as also Lux.
The main problem is that presence beacon script hijacks bluetooth usb stick and can not perform any other bluetooth action. A workaround is to get a second bluetooth dongle and use it as interface with SensorTag. Before starting to fill all my usb hub ports with BLE dongles, does someone knows a way to use BLE donge as presence and also get connected to another device?

Happy that it's working with python.
I'm not the writer of this script!!!
I'm in the same situation, I'm not able to let it start at boot...

Hi,

@woody :
Are-you sure , it didn't work ? You have a different output than mine but yours says it works too. Look : active since 4min 3s ago !

sudo /etc/init.d/check_beacon_presence status
● check_beacon_presence.service - LSB: This daemon manages the bluetooth low energy device detector : check_beacon_presence
Loaded: loaded (/etc/init.d/check_beacon_presence)

Process: 366 ExecStart=/etc/init.d/check_beacon_presence start (code=exited, status=0/SUCCESS)

So finish the install,

Code: Select all

sudo update-rc.d check_beacon_presence defaults

reboot, and check .log with a tail /var/log/check_beacon_presence.log

Posted: **Monday 09 May 2016 22:28**

The status is the same

The log is stuck at

Code: Select all

2016-05-09 22:24:00,747 - root - INFO - Connect to bluetooth device 0

But if I stop it

Code: Select all

sudo /etc/init.d/check_beacon_presence stop

restart it

Code: Select all

sudo /etc/init.d/check_beacon_presence start

I get this

Code: Select all

pi@raspberrypi:~$ sudo /etc/init.d/check_beacon_presence status
