Hi … I have the following SMS Forward rule, forwarding any SMS recieved to one number on my mobile.
This has been behaving well until recently - coincidently when I upgraded to the 07.06.10 release.
I, and my mobile operator, believe that it is forwarding the message multiple times (x3 in this case).
It seems to also be happening with Events Reporting, where I have the rule below sending an SMS to a single number.
In this case, it sends 5 SMS’s.
Thanks … Mike
Hello,
Currently, it’s a bit difficult to understand what’s going on without more details. To help clarify, could you access your router’s SSH/CLI and run this command:
logread -f
Then, send some messages with “SMS Forwarding” enabled and share the output. With this information, we’ll be able to investigate the issue more effectively.
Best regards,
Mike

Many thanks

I am doing some further testing because with a reboot, I am still seeing the multiple sent messages in Events Reporting. I will report back.
Hi,
Based on the logread information, it’s evident that only one message is being forwarded.
Could you please share the results of your further testing?
Best regards,
Mike

I believe the multiple PDUs are due to the 160 character limit that forces message concatenation. I have ran further tests to check the behaviour above.
SMS of 160 characters = 1 PDU sent
I assume this is expected behaviour for the RUTOS.
The earlier test messages were short.
Unfortunately my mobile provider detects this and sends me long messages about how I might have a virus. It was just coincidence that I first started receiving SMS that were over this 160 character limit, on the day I did the firmware upgrade.
Hi,
This behavior is expected from all mobile service providers. Even if a message consists of multiple PDUs, it is still sent as one message.
You can verify this by sending a message to your router. When the symbol count exceeds the PDU length, it will automatically continue to another PDU (second), but it will still be sent and received as one message.
Best regards,
Mike
