How to restart services with python ?

[tontze]

Hi !

I have a conflict problem with my bt beacon and miflora sensor. Whenever i run miflora update, beacon stops responding, so i thought to restart
beacon service in the end of a miflora python script. How is it easiest to do ?

I would have started the beacon service as a systemd service. Then it will be automatically restarted by the Linux system if it terminates for some reason. If you do not know how to start a script as a systemd service, you can find an example on github, bengtner/GPIOinput. You write a small service definition file and put in /etc/systemd/system, then use the systemctl command to enable the service.

Beaconing is made by this wiki :

http://www.domoticz.com/wiki/Presence_d ... gy_Beacon)

And is it run from init.d

It runs hci0 port, but if anything else accesses it, it will stop responding, im not sure does it die, or just doesnt respond anymore ..

Im noob on this so ..

EDIT: by checking status of a service, i see it is running, but not responding

I see, since status reports "running" no system surveillance will solve your problem.

I'm sorry, but I can't help you in this matter.

Ok, thnx anyways, an attempt was made

Does anyone else have ideas ? I simply would like to "sudo /etc/init.d/beqacon restart" service at the end of miflora script. Mi flora is run every 6hours.

I just dont know how to do it with python :/

Something like this?

Code: Select all

import os
os.system("sudo /etc/init.d/beqacon restart")

Make sure sudo is not asking for a password.

Ease from there you'll have the ability to download Fildo the within the Fildo App. The Fildo Apk could be downloaded.

hello, iv had same problem as you, so i changed script
with this command

Code: Select all

os.system("timeout 2 hcitool lescan 5")

miflora works OK in my tests and it works without sudo

Code: Select all
