Wouldn't be better to just add to the Expansion dock the charging/battery capabilities? There is a lot of room for that in the PCB.

@Costas-Costas Yes, I didn't look deep enough so I was just looking at the default pin 0. Seems they have not updated the page with the Omega2 pins, but just to be clear, I am using the dock and the pins layout is also not the Omega2. I was only testing using pin 0 until you mention it. Oh well, Onion has a LOT of updating to do in their hands, I only wish they would release the eBook already, but don't want to rush them or they will miss parts in that one too

Does anyone know where to get how to's and/or step by step instructions on the Omega2?

I am trying to see how to work the Device Explorer but no idea on how exactly works. I am lost and since there is NO project book finish yet, well I am stuck on how to do stuff with the Onion2. I want to:

Send commands to Omega2 via the web such as turn the onboard led, read temperatures when connecting a sensor, turn the gpio to output and make it high(1) or low(0), all the good stuff.

Since Omega2 is new, well, there is really nothing I can find that will point me in the right direction of how to do the above things. A tutorial on doing basic tasks would be great.

Thanks

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
