Do you have any experience with devices like this one?
https://www.aliexpress.com/item/16-PORT-GPRS-MODEM-professional-SEND-RECEIVE-SMS-MSM-Gateway-Mobile-Recharge/1721780447.html

Is able smstools to deal with this?

As i can see there is only one usb conector.
Smstools will see this as a single modem or as 16 because inside that is usb hub also?

Thank You.

If the device provides independent serial interface for each module, like /dev/ttyUSB0, /dev/ttyUSB1 and so on, it can be used with SMSTools3.

I do not know if there is a hub inside. You have to ask that from the seller.

The seller is telling me that i will see 16 serial devices under linux/windows, so... i will order one piece and make some tests.

Keke, nice software.
Thank You.

Hello,

I got that device, and it works. The modems are seen like ACM devices. My config that worked:

[T0]
device = /dev/ttyACM0
incoming = yes
outgoing = yes
signal_quality_ber_ignore = yes
cs_convert = yes
check_memory_method = 5
status_signal_quality = no

Is not working without antena, and every modem has his own power switch.
Speed for one modem: 4-5 sec, theoretically volume 11000-12000/hour.
No test with 16 sims yet.

Hello,

I have a question, in de smsd.conf, which is the code, because I tried but only can send by 1 modem, I don't understand because not sent by multiple modems

my code:

# Global configuration
# Configuration smsd.conf
#
checkhandler = /usr/local/bin/load_balancing.sh
#
devices = GSM1,GSM2,GSM3
#
logfile = /var/log/smsd.log
#loglevel = 6
loglevel = 5
delaytime = 0
delaytime_mainprocess = 0
internal_combine = yes
receive_before_send = no
logtime_ms = 1
max_continuous_sending = 600
incoming_utf8 = yes
umask = 111
stats_interval = 0
#checkhandler = /usr/local/bin/load_balancing.sh
smart_logging = yes
#
trust_outgoing = yes
stats = /var/spool/sms/stats
outgoing = /var/spool/sms/outgoing
checked = /var/spool/sms/checked
failed = /var/spool/sms/failed
incoming = /var/spool/sms/incoming
sent = /var/spool/sms/sent
#
autosplit = 3
#
#Timers for errors (specify how many seconds stop on error)
blocktime = 3
errorsleeptime = 3
#
[queues]
#ALL = /var/spool/sms/all
Q1 = /var/spool/sms/modem1
Q2 = /var/spool/sms/modem2
Q3 = /var/spool/sms/modem3
#Q4 = /var/spool/sms/modem4

And the conf for modem is the same.

Hello cgambi,

The load balancing script has a bug. The maximum value of counter is limited to 255 by oversight, and I think that in your system counters are much more than that.

Here is a fixed version of load_balancing.sh:

Hello Keke
i made the changes, and i'm still sending by 1 modem. (the first one in the queue).

here is my config file GSM 1, 2, 3:

voicecall_ignore_modem_response = yes
regular_run_interval = 60
regular_run_cmd = AT+CSQ
regular_run_logfile = /var/log/smsd_run_GSM1.log

Pleas help

Check the sent message file in /var/spool/sms/sent directory. Has it a Queue: header?

Is a command formail installed in your system? If it's not, it's usually available in procmail package and this command is required by the script.

thx for the answer.

I already have the formail command, so that can't be the problem.

but, the sent message file doesnt have any queue header. how do i put that header?

The checkhandler should put the Queue header into the file.

Try the following:

- stop the smsd if it's running

- create an outgoing file as usual, without Queue or Provider headers, with a name test1

- run the checkhandler manually: /usr/local/bin/load_balancing.sh /var/spool/sms/outgoing/test1

What happens? Is there any errors seen?

Also cat /var/spool/sms/stats/*.counter and show the results.

i ran the checkhandler with a test file as you said, and nothing happened, no error.

pi@raspberrypi:/var/spool/sms/outgoing $ ls
test1
pi@raspberrypi:/var/spool/sms/outgoing $ /usr/local/bin/load_balancing.sh /var/spool/sms/outgoing/test1
pi@raspberrypi:/usr/local/bin $ cat /var/spool/sms/stats/*.counter
GSM1: 1478
GSM2: 0
GSM3: 0

i still have the test file in the outgoing folder
this is my test file:

To: 5699791XXXX

Hello, this is the sms.


after run the command, the file now is:

To: 5699791XXXX
Queue: Q2

Hello, this is the sms.


EDIT:

in the log file smsd i have this error:

2017-07-24 12:44:25.954,5, smsd: Wrong provider queue Q2 in file /var/spool/sms/outgoing/test1

Settings in the config file must be equal with settings in the load balancing script. You originally had queues Q1 and so on, but now you are using GSM1 and so on, which is not correct. Either change the smsd.conf, or change the script:

# Settings for this script: STATSDIR=/var/spool/sms/stats MODEMS=( GSM1 GSM2 GSM3 ) QUEUES=( GSM1 GSM2 GSM3 )

i checked the names and its ok now. i set the queues as Q1 - Q3 and actually, if i create now a test1 file with the queue header, it work, and the sms its sended by the specific modem.

when i send a sms by the playsms api its seems like the messages are not getting the header.
what could be wrong?

Load balancing is ignored if there is Queue or Provider header in the file. When testing, you should not create Queue header by yourself.

Please check which headers are created by the playsms, as it may override the load balancing.

ok, i checked the file, and when i created with no headers and then run /usr/local/bin/load_balancing.sh /v
ar/spool/sms/outgoing/test1 the file now has a queue header when open it again.

the test file only have:

To: 569XXXXXXXX

hi i'm a sms


and after run the command now i have

To: 569XXXXXXXX
Queue: Q2

hi i'm a sms

Did you check if playsms is creating Queue or Provider header? I do not have playsms installed, so I cannot check what kind of configuration it has. You could stop the smsd and create a new message with playsms. Then you could check what kind of file was created to the outgoing directory. If there is Queue (or Provider) set, it must be disabled in the playsms side. How to do that, I do not know.

We're making a load balancer in our custom platform. so we're fine with that.
But, there are some troubles with 2 things:

1. i couldn't send more than 6.x (Average) sms per minute. is this the maximum send rate? or should be faster? is there a way to optimize this?

2. I can read in the log file that the sms are sended, but how can i know they delivery status? and if someone reply the sms, where can i read the incoming sms?

we've tested replying some sms, but nothing happens. even in the log, there's no clue about sms received
