auto run from Pi's Shell

[YXGuan]

Hello Martin,

First of all, thank you for the amazing software!

My question: is there a way to pair Pi to my phone and run some Bluedot codes automatically every time Pi boots up?

The issue I have: it gives me an error when I tried to run my program from Pi's shell: No module named blue dot

Here's a screenshot of my error: screenshot

Could you help me out?

Thank you for your time.

I noticed that you did a pip3 (i.e. install it into your python3 setup) but then used the python command which by default will run python2.

Try using the python3 command instead.

I would encourage you to head to the Raspberry Pi Forum raspberrypi.org/forum you will get a faster response and there is a much larger group of people who can help you.

A few points:

• as @ukBaz points out, you are trying to run your program using Python 2 e.g. python - use python3 instead e.g. python3 /home/pi/path_to_program.py
• you only need to pair your phone once, you wont need to do it everytime the pi boots
• the simplest way to get your program to boot is probably by adding the command to rc.local - if you search Im sure you will find a tutorial.

I am closing the issue as it isnt a bug with BlueDot.

Apologies in advance to Martin for posting this, but there are various advantages to using systemd over rc.local. I find the following a useful reference: https://blog.usedbytes.com/2019/11/run-at-startup-without-rc.local/

Many many advantages of using systemd. The key disadvantage being that its a lot more complicated.

@martinohanlon @ukBaz Thank you all, Martin and Barry. Like you guys suggested: python3 fix the problem. Thanks again, it's really helpful. Have a wonderful day!
