Hay all, So I wish to know if someone can make a 3g rssi signal strength indicator in luci This will help loads with users that are on 3g net only.

I found this but its not grate to set antennas up with

wiki wrote:

For troubleshooting or locating the best position for the USB Dongle, you can use

gcom info -d /dev/ttyUSBx
from the console. This tool will report signal strength, but also network registration and SIM status. If it returns a port-in-use error because your connection is already up, try
gcom -d /dev/ttyUSBx
where x represents a port number not used by the wan connection itself.
gcom returns the signal quality in RSSI (Received signal strength indication) and in BER (Bit error rate, reported in percent). A higher RSSI value represents a stronger signal - scale is from 0 to 99, where 1 is the lowest detectable signal and 31 a very good signal. Don't expect your signal to go all the way up to 99, though. If BER returns 99 it means not known or not detectable.

: Although I found the above information all across the net, I made different observations: My 3G modem is a ZTE K3565-Z which features a LED to show it's status (Not Connected, GPRS, UMTS). With a reported RSSI value of around 17 I only get GPRS while a value of 4 allows for UMTS access.
You can also add the AT command

""      "AT+CSQ"
to your chat script to check signal quality.
Command return is "+CSQ: <rssi>,<ber>" and looks like this in logread:

send (AT+CSQ^M)
expect (OK)
^M
AT+CSQ^M^M
+CSQ: 11,99^M
^M
OK
-- got it
If you have problems establishing a connection and multiple modem devices (/dev/ttyUSB0, /dev/ttyUSB1, …) are present, try all of them. Some may not work at all while others seem to work at first, but will give a NO CARRIER during the connection process.

Thanks Raster.

Can someone help out with this? There is lots of ppl who would find this handy.

TP-link have it in there 3g routers.

The TP-link one only updates when it 1st connects to the modem. But one simler with a dbm info would help so so much for anyone who takes there router out and about or if just looking for a new cell site when the other cell gos down.

Works well thanks,

Siła sygnału:38%

If we could get that put in to the Luci utms connect wan it would be grate big_smile

I have made a ticket over on http://luci.subsignal.org
Ticket http://luci.subsignal.org/trac/ticket/522
Maybe they can code it in? would be nice.

And thankyou for both your help to get to see a % of signal is going to make my life alot easyer.

You cannot use the same interface for connection and 3ginfo. Change interface in 3ginfo config (/etc/config/3ginfo).

Nice. It works now.
As "TheRaster" already has written, it would be nice to integrate it to Luci

Hi.

I need some help.

I need help for the indicator signal 3G/4G.

I downloaded this: http://ecco.selfip.net/attitude_adjustm … /packages/ (3ginfo_20130214_all.ipk)

Insert the command in Putty above, but without effect.

It's the first time I use OpenWRT firmware. I'm new in these things.

Best Regards

Use at command, depends on vendor, like: "AT+ZPAS? (ZTE) AT_OCTI?/"AT_OWCTI? (option) etc. See my 3ginfo: https://github.com/obsy/packages/blob/m … ginfo.gcom

Modem vendor is huawei, I add "AT\^SYSINFOEX" and logread output is:

I tested (for Huawei usb dongle) this 3g.gcom script (add to gcom)

opengt
 set com 115200n81
 set comecho off
 set senddelay 0.02
 waitquiet 0.2 0.2
 flash 0.1

:start
 send "AT\^SYSINFOEX^m"
 get 1 "" $s
 print $s

:continue
 exit 0

call:  luci.sys.exec("comgt -d /dev/ttyUSB1 -s /etc/gcom/3g.gcom | grep 'SYSINFOEX' | grep -oE [^,]+$")

the output is (not always):

AT^SYS
^RSSI: 4
INFOEX
^SYSINFOEX:2,3,0,1,,3,"WCDMA",41,"WCDMA"

OK

^RSSI: 5

on web gui displayed: AT^SYSINFOEX "WCDMA"

How to edit 3g.gcom script to display WCDMA or EDGE or HSDPA (without quotes also)...
