SMS not received - andrepneves@gmail.com - 20.03.2025
Hi,
We are using a LogicMachine5 Reactor GSM to send SMS in case of alarm of some variables. The script uses a for to send the message to multiple numbers, with a delay between them. You can see the code below (I changed the phone numbers with generic ones for security purposes).
The problem is that not every SMS is received. What could be causing this? Is there any way to check if the SMS is received?
Thank you in advance,
André Neves
Code:
require('user.sms')
Nrs_Tlf={'123456789',
'987654321',
'147852369'}
tab = string.split(name, ">")
if value==1 then
Alarme="Alarme:\n"..tab[2].."\n"..timestamp
elseif (value==2) then
Alarme="Alarme Reconhecido:\n"..tab[2].."\n"..timestamp
elseif (value==3) then
Alarme="Alarme Reposto:\n"..tab[2].."\n"..timestamp
end
if (value<4 and value>0) then
for i = 1, 3, 1 do
sendsms(Nrs_Tlf[i],Alarme)
os.sleep(30)
end
log("SMS enviados")
else
log("Out of bounds.")

See this post on how to add additional logging to the SMS script:

Hello,
I've updated the scripts as indicated on the link from @admin but some users are still not receiveing the messages. It's not always the same user, it's random.
In the alerts, the SMS handler indicate that all messages are sent but not all are received.
Please help, the client is using this LM to check high priority alarms and with this behavior is system simply isn't reliable.
Thanks in advance.
BR,
André Neves

Restart the SMS script after making changes to the library.
RE: SMS not received - andrepneves@gmail.com - 26.05.2025
Did a reboot to the LM. There are still some SMS that get lost in the process.
RE: SMS not received - admin - 26.05.2025
Check that you have replaced AT:read() in the library correctly. When done correctly it will log everything that the modem sends to LM.
RE: SMS not received - andrepneves@gmail.com - 26.05.2025
Chage AT:read with the version here https://forum.logicmachine.net/showthread.php?tid=5403&pid=38043#pid38043
when sending SMS the log looks like the 1st image.
In standby, it's always logging 'timeout' as shown in the second image
RE: SMS not received - admin - 26.05.2025
Update the function once more, it won't spam the log with empty messages.
Code:
function AT:read(timeout)
local char, err, timeout, deftimeout, line
-- default timeout is 2 seconds, converted to 0.1 sec ticks
timeout = tonumber(timeout) or 2
timeout = timeout * 10
deftimeout = timeout
-- read until got one line or timeout occured
while timeout > 0 do
-- read 1 char
char, err = self.port:read(1, 0.1)
-- got data
if char then
-- got LF, end of line
if char == '\n' then
-- convert to string and empty buffer
line = table.concat(self.buffer)
self.buffer = {}
line = line:trim()
-- return only lines with data
if #line > 0 then
log('read line', line)
return line
-- reset timeout
else
timeout = deftimeout
end
-- ignore CR
elseif char ~= '\r' then
table.insert(self.buffer, char)
end
-- read timeout
elseif err == 'timeout' then
timeout = timeout - 1
-- other error
else
break
end
end
line = table.concat(self.buffer)
if #line > 0 then
log('read timeout', line)
end
return nil, err
endPost your logs when SMS does not reach the recipient.

This error indicates poor network signal quality. Check this thread on how to monitor signal level: https://forum.logicmachine.net/showthread.php?tid=5369&pid=34692#pid34692
