Fix Python DLT SMPP Integration
Budget: ₹600 – ₹1,500 INR
I have a working SMPP client in Python, but ever since our traffic moved to India’s DLT region the messages never leave the bind. The vendor confirms that “DLT parameters are not added,” so nothing is accepted and no delivery receipts arrive.
What I need you to do
• Inspect the existing Python code (built around smpplib) and pinpoint why Sender ID, Entity ID, Template ID and the additional PE Id are not being inserted in the submit_sm PDU.
• Add those parameters in the exact TAG-LEN-VALUE format required by the operator, then test end-to-end until “message sent” and a valid DLR are both confirmed.
• Supply the fixed script with concise notes showing which blocks were changed so I can audit the patch quickly.
You must already be comfortable with SMPP v3.4, DLT headers, TLV encoding and Python 3.x. A short screen-share or sample log proving the first successful delivery will close the task.
