TX-power value ouput using API

RouterOS Scripting
1

Hi all!

I am using PEAR2/Net/RouterOS and PHP to get some monitoring information. I can’t figure out how to get specific info from wireless interface. How to write a request to get tx-power of wireless card. I am able to get current-tx-power which is long string, but not tx-power integer value.

Thanks

I’m not sure I follow… how would you do that from terminal? How does the long string differ from the integer value?

When I issue command in terminal

/interface wireless> :put [get 0 tx-power]

I get value of transmit power which I have entered in wireless card’s Tx Power tab previously.
It would be nice to get this number without parsing current-tx-power

Assuming the interface’s name is “wlan1”, you should be able to get the tx power like:

$printRequest = new RouterOS\Request('/interface wireless print', RouterOS\Query::where('name', 'wlan1'));
$txPower = $client($printRequest)->getArgument('tx-power');

If that alone doesn’t work, try adding “detail” and/or “stats”, e.g.

$printRequest = new RouterOS\Request('/interface wireless print detail="" stats', RouterOS\Query::where('name', 'wlan1'));
$txPower = $client($printRequest)->getArgument('tx-power');
5

Unfortunately it doesn’t work for me. It returns empty string.
BTW I am using ROS v6.0rc11

What does

$printRequest = new RouterOS\Request('/interface wireless print detail="" stats', RouterOS\Query::where('name', 'wlan1'));
var_dump($client($printRequest)->getAllArguments());

output?

I am not very strong in PHP :slight_smile:
I hope did everything right.
Output:

array (size=1)
  'message' => string 'unknown parameter' (length=17)

Looks like command doesnt like ‘stats’
Once again output:

array (size=28)
  '.id' => string '*4' (length=2)
  'name' => string 'wlan1' (length=5)
  'mtu' => string '1500' (length=4)
  'l2mtu' => string '2290' (length=4)
  'mac-address' => string 'xx:xx:xx:xx:xx:xx' (length=17)
  'arp' => string 'enabled' (length=7)
  'interface-type' => string 'Atheros AR92xx' (length=14)
  'mode' => string 'ap-bridge' (length=9)
  'ssid' => string 'xxx' (length=6)
  'frequency' => string '2412' (length=4)
  'band' => string '2ghz-b/g' (length=8)
  'channel-width' => string '20mhz' (length=5)
  'scan-list' => string 'default' (length=7)
  'wireless-protocol' => string '802.11' (length=6)
  'wds-mode' => string 'disabled' (length=8)
  'wds-default-bridge' => string 'none' (length=4)
  'wds-ignore-ssid' => string 'false' (length=5)
  'bridge-mode' => string 'enabled' (length=7)
  'default-authentication' => string 'true' (length=4)
  'default-forwarding' => string 'true' (length=4)
  'default-ap-tx-limit' => string '0' (length=1)
  'default-client-tx-limit' => string '0' (length=1)
  'hide-ssid' => string 'false' (length=5)
  'security-profile' => string 'xxxx' (length=14)
  'interworking-profile' => string 'disabled' (length=8)
  'compression' => string 'false' (length=5)
  'running' => string 'false' (length=5)
  'disabled' => string 'false' (length=5)

Now I dont know from where it takes this value I can see in terminal.

for wireless you have to use

print advanced

and tx-power will not be reported if tx-power-mode=default

and tx-power mode only can safely be used if you have to reduce tx-power of the card.

Paldies janisk!

My tx-power-mode=all-rates-fixed.
I tried command you suggested in terminal. Now I see tx-power among lot of parameters. But question is does php API allows me to use the command because var_dump returned:

array (size=1)
  'message' => string 'no such command' (length=15)

Edited later:
Thank you both again. I got it working using this code.

$printRequest = new RouterOS\Request('/interface wireless print advanced=""', RouterOS\Query::where('name', 'wlan1'));
		$txPower = $client($printRequest)->getArgument('tx-power');
10

using demo python api:

/interface/wireless/print
=advanced=
=.proplist=tx-power

<<< /interface/wireless/print
<<< =advanced=
<<< =.proplist=tx-power
<<< 
>>> !re
>>> =tx-power=17
>>> 
>>> !done
>>>

and for comparison:

/interface/wireless/print
=.proplist=tx-power

<<< /interface/wireless/print
<<< =.proplist=tx-power
<<< 
>>> !re
>>> 
>>> !done
>>>

maybe boen_robot can shed some light on use of PHP API

iq25 figured it out already :slight_smile: .

If .proplist is to be included, it’s as simple as

$printRequest = new RouterOS\Request('/interface wireless print .proplist=tx-power advanced', RouterOS\Query::where('name', 'wlan1'));

.proplist was used to give useful example of the result. Other way it would be overcrowded with irrelevant data.
