I haven't found anything either yet. Was it forgotten by the Onion team maybe?? Last post that said it was ready to be posted, it was a year ago.....

@Victor-Tagayun
I have tried it and it works, but not extensively. You have to install python though.

@Przemyslaw-Downar

Thanks!!! Working again. Will wait until they fix the latest firmware now.

I can verify that b162 is not working. I had a good booting process with b160 and have been installing the updates manually ever since I got the Omega2 (Not the +) and this b162 is broken. get the same Fatal exception: panic in 5 seconds too. In keeps rebooting over and over....

How can I restore the b160 back ?

Never got to a bad firmware before.

@VIKAS-MALIK Have you followed the steps mentioned here : ??

https://wiki.onion.io/Tutorials/PHP-DHT11-DHT22-Sensor-Examples

It uses PHP for this tutorial.

I am starting to play around with Python and I saw that the python Twisted library was added with the b158 update but there is no info about how to use it or install it in the online docs. Omega: Can you point me in the right direction please?

Thanks

One more vote to have it open source

Thank you Costas!! That was it. That should be it now. And thanks everyone else too for their help.

Ok. I am now trying Python to run the cron script. I have done the following steps:

1 - Upgraded to latest firmware b157
2 - opkg update
3 - opkg install python
4 - opkg install python-light pyOnionGpio
5 - did a reboot
6 - got the following code into a filename called test2.py in the root folder :

import time
import onionGpio

gpioNum = 18
gpioObj = onionGpio.OnionGpio(gpioNum)

set to output

status = gpioObj.setOutputDirection(0)

alternate the value

loop = 1
value = 0
while loop == 1:
# reverse the value
if value == 0:
value = 1
else:
value = 0

# set the new value
status  = gpioObj.setValue(value)
print 'GPIO%d set to: %d'%(gpioNum, value)

time.sleep(5)

7 - chmod the test2.py to make it executable. 0744
8 - Now I go to the crontab -e and inserted the following line:

12 6 * * * /test2.py > /tmp/test.log 2>&1

9 - restarted cron
10- waiting to execute
11 - got this at test.log :

/test2.py: line 1: import: not found
/test2.py: line 2: import: not found
/test2.py: line 4: gpioNum: not found
/test2.py: line 5: syntax error: unexpected "("

So I am guessing for some reason, it didn't find the import file onionGpio.py but I checked already and it is in the location it is suppose to be which is /usr/lib/python2.7/

I am wondering if I missed a step?

Thanks again for all your help

It does return the exact cron job:

5 13 * * * /www/php/test.php > /tmp/test.log

I was looking at the docs and they do mention the php-cli to be able to run from the command line but it works when I doit manually, but again, when using the cron it doesn't. So you think SH or Python would be easier for a PHP guy to grasp the basics?

Thanks Brad and Luciano and Don,

Guess going to have to learn another language

tried running from the command line and got the following:

root@Omega-AA00:/# /www/php/test.php
/www/php/test.php: line 1: can't open ?php: no such file
/www/php/test.php: line 3: include: not found
/www/php/test.php: line 5: syntax error: unexpected "("

Thanks again

I am starting to do some testing with Omega2 using php, I have installed PHP7 and PHP7-cgi and using the browser, I can go to the PHP file at /192.168.1.190/php/test.php and run it and it does work (Turns a led on) once it is executed. BUT when trying to use a cron job, it does nothing.

I am using the following :

5 13 * * * /www/php/test.php > /tmp/test.log

to run it at 1:05pm and send the output to test.log

and also making sure the test.php is chmod 755

then do a restart of the cron:

/etc/init.d/cron restart

and wait, nothing, not even the log file, it was created but 0 bytes.

Maybe I am missing a step?

Anyone has an idea of why is not runing the php file?

Thanks in advance

@Costas-Costas Sorry for my ignrance but what do you mean that I need an Omega2+ or Omega2 with a USB flash drive???

@Costas-Costas Yes, after much trial and error I got the PHP code to work now
Thanks though for the online converter, it might come handy in the future.

I had use Blynk with Arduino but not that much, only a few tests and did something else. Will take a look at it again.
Thanks!

After much testing, I found the answer So now I can use the Device Explorer App from the cloud, but as Costas said, it is always better to control from our own web interface. Thing is, I can't seem to find and PHP examples on using the gpio pins. The code that produces the Device Explorer also, relies on the onion server. Would there be a way to directly connect to the Onion2 instead of going from our own web server to the onion server and then to the Omega2????

@Costas-Costas said in Cloud API documentation?:

{"gpio":"1","value":"1"}

Great, I am just wondering, what option do you choose first, onion, uci or service?

See the following screenshot and it these are the steps to follow?

Thanks

Have a question to you guys regarding Device Explorer App in the cloud:

How does one actually make it work? Can someone tell me the steps to do, let's say, set the onborard led to heartbeat mode...

Do I need to copy the commands and paste it somewhere? I have no clue on how it actually works the Device Explorer App and any help would be appreciate it.

Just to clarify, it was a command but I never mention that it was fast-gpio, but the docs said one way and it was actually different. I will look around and see which one is the one I got the error. I just thought it might help Costas from something that happened to me too.
