Corrupt output from `gsm show span n`
10 years 6 months ago #9153
by ajs_derby
Occasionally the output of the Asterisk CLI command
CLI> gsm show span n
is corrupt. For instance, this is an actual output;
Which is good. But then we have this;
As you can see, the IMSI here has been replaced by another message "+CPIN: READY".
I can obtain the IMSI from within the Asterisk CLI using
CLI> gsm send at 15 AT+CIMI
but I need to be able to run this from within a script, and
# asterisk -rx 'gsm send at 15 AT+CIMI'
does not return the response from the command.
Do you know if there is some way of either (1) restoring the correct information in the output of `gsm show span n` or (2) capturing the result returned by a `gsm send at` command issued within a script?

Hi，
This is Rick,so sorry to reply you delay.
You need to redirect the output stream,so that you can capturing the result via script.
For example:
#! /bin/bash
asterisk -rx 'gsm show spans'>test.txt
cat test.txt|while read line
do
echo $line
done
I guess you want write a program send AT,please give me your e-mail.I can give you some document.

I tried
and this worked as expected, with the output of `gsm show span 15` in the file "test1".
But when I tried
the file was empty; there seemed to have been no response from the AT command, exactly as if I had left the output to STDOUT. So redirecting the output to a file seems not to be enough, by itself, to capture the AT command output.
To make it absolutely clear, it's the IMSI (serial number of the SIM) that I am really interested in -- the intention is that a bunch of SIMs will be rotated through the machine, with each one being used until its message allowance is used up. I want the IMSI so I can keep track of how many messages have been sent using each SIM, irrespective of which slot on the card it was inserted. The corrupt `gsm show span n` output probably is a separate issue.
#asterisk -rx 'gsm show span 15' > test1
# cat test1But when I tried
# asterisk -rx 'gsm send at 15 AT+CIMI' > test2
