For the fellas out in the wild figuring out how to read the serial port on console at least on a bash script here's the link to it: https://pastebin.com/bHic0sBL

Basically on a fresh omega2/+ you need to install at least the stty command package which comes with opkg install coreutils-stty.

Further on the condition you can place an array with strings to compare reading card validation or compare to a file with cards on each line..

You can obtain the lists with your preferred programming language then, node, python, php etc.

Finally with only $20 you can build a linux based access control solution!!

Is there any chance that the filter support is removed again, I keepgetting the error throws: Exception message: Call to undefined function filter_var()

@Zheng-Han said in omega2 uhttpd php7-cgi Bad gateway:

@Mentor-Gashi try a factory restore firstboot and a clean install of onion-os and oos-app-editor it should configure php for you automatically
make sure you are at the latest firmware build oupgrade -l

Thanks, the -l flag did indeed upgrade the firmware despite the regular check was claiming the firmware was up to date.

Going to give it a try if I can get a use of it

Greetings folks,

been trying for 2 hours to setup php on omega2, I followed this tutorial:
https://docs.onion.io/omega2-docs/installing-and-using-php.html

After I add the list interpreter ".php=/usr/bin/php-cgi" and option index_page 'index.php' and restaring the uhttpd /etc/init.d/uhttpd restart I get the Bad Gateway error, and nothing else. Tried a few times, factory reset the omega but the results were same. Then lately I tried the upgrade onion-os, and when I navigate to Code Editor on http://192.168.3.1/OnionOS/ I get the same error as below.

Bad Gateway
The process did not produce any response

Tried to check if firmware is up too:
`root@Omega-99EF:/etc/opkg# oupgrade

Device Firmware Version: 0.1.10 b160
Checking latest version online...
Repo Firmware Version: 0.1.10 b160
Comparing version numbers
Device firmware is up to date!`

Anyone having this error recently? How would I get php working?

@Maximilian-Gerhardt

Thanks a lot for the tips and the prompt resonses, I finally was able to see the cards being read, even without level shifters.

For starters or anyone struggling, with less experience on boards like me.

Connect to o2/o2+ via terminal perform the opkg update, then install the screen command by entering: opkg install screen on your terminal. Wait till the screen is downloaded and be configured.

Then plug wires, RDM6300 TX to o2/o2+ Rx1 and RDM6300 RX to o2/o2+ Tx1. Assuming you've plugged the 5v, GND, and the RDM6300 is already powered up (the green led is on).

To listen the RDM6300's serial type: screen /dev/ttyS1, on your terminal, screen will open like an editor on the terminal (vi/nano), blank page, swipe the cards and you'll see the hexes being read.

Finally ensure you lower down the returning power to omega with resistors as @György Farkas recommends.

@Maximilian-Gerhardt said in Omega2/+, expansion dock and RDM6300:

package

Thanks a lot for the extended explanation, I will be using some shifters to resist the power back to the board.

I did use 5v as you may see here:

On the other side there are TX+,TX-, RX+, RX-, which of them are UART1 pins? Sorry for being so dumb really trying to learn

Despite that fact of resistors, isn't there any example other than the default documentation of how I could read the rdm6300 input, except cat/python instructions? In arduino/clones I didn't need resistors though I was able to read the data :(, confused a bit.

Greetings folks,

been trying for this weekend to setup LAMP like environment on O2+ (with usb ext4-storage), after several trials and community's help found out that mysql-server packages are missing around but nothing special on that, there is sqlite3 thank God.

Now I found out that I need the rewrite rules like the ones on apache that you define in the htaccess files for a site to get the pretty urls working, trying to achieve this because I embarked a laravel successfully on O2+, migrated the database and now stuck on the urls. This is the actual htaccess example of the L5.5 https://pastebin.com/7LnpjaWL

Anybody got successful with this issue? or should I try to get uhttp replaced with apache?

@György-Farkas commented out the lines you mention but the mysql-server remains as unknown package. Giving up on mysql by now and giving a try to sqlite3.
