rtrMessageSegmentTooLong Error

If you encounter an error like this:

Jul 27 12:43:21 RTR01 textpass: Application MyApp1 of ID 34 sent unexpected data - see 'RTR Operator Manual' [3 times]


Jul 27 12:43:21 RTR01 tp_hub: App: 'MyApp1' - 'submit_sm' on outside session caused 'rtrMessageSegmentTooLong' (0x0400000d).


Sent SMPP error 0x0066: Permanent error sending message [3 times]

in the var/log/messages log, and the message fails to send, it is likely caused by the length of the message segment.

Problem

NewNet Lithium is unable to process concatenated messages when any individual message segment exceeds 133 bytes, as this prevents the necessary user data header from being added, resulting in a rtrMessageSegmentToolong error.

For more on this error, please see the RTR Operator Manual, 11.4.2 AO-MT-AO Failure Scenarios.

Solution

To resolve this issue, ensure that the SMS application splits long messages into individual segments of 133 bytes or less, allowing space for the required user data header.
