Good morning everyone !
Once I reboot my raspberry; this is what I can find in the smsd logs :
2019-10-20 12:42:33,7, MODEM1: Command is sent, waiting for the answer. (15)
2019-10-20 12:42:48,7, MODEM1: No answer, put_command expected (OK)|(ERROR)|(0)|(4), timeout occurred. 3
And this never stops.
In order to have the modem responding to commands, I have to manually unplug it and plug it again.
Once I unplugged and plugged again the modem, and restart smsd; it works fine.
This situation is a bit annoying for me, since I would like the setup to be able to recover on its own.
I use one raspberry, which is connected to a sitecom USB hub.
The sitecom USB Hub is connected to the power also; in order for the modem to receive the proper energy it needs.
The Huawei modem is connected to the sitecom USB Hub.
Raspbery > USB Hub > Huawei e3531
I have a file which turns the device into "huawei" under /dev, and smstools is connecting to this one.
/etc/udev/rules.d/99-usb-serial.rules
SUBSYSTEM=="tty", ATTRS{idVendor}=="12d1", ATTRS{idProduct}=="1001", SYMLINK+="huawei"
I am suspecting that scripts and services are not launching in the correct order, which could maybe explains that the modem does not answer.
But that's just a theory; I am not sure what is wrong.
I am not sure where to start in order to troubleshoot this problem.
I was wondering if maybe you had a hint :) ?
Here is my smsd config :
#Main config
devices = MODEM1
loglevel = 7
# logfiles
stats = /var/log/sms/stats
logfile = /var/log/sms/smsd.log
#All alarms will trigger script alarm_handler.sh

#All new sms status will trigger event_handler.py script
eventhandler=/root/raspnode/event_handler.py
incoming_utf8 = yes
# Default queue directory = /var/spool/sms
outgoing = /var/spool/sms/outgoing
checked = /var/spool/sms/checked

# report folder

#350 sms per days max

#report = yes
#For development purpose :

Thank you in advance for your help !!
