Hi,

I set up a GSM SMSC and created a SMPP account so that the SMPP client (my application) can receive SMS which received over the GSM modem.
I can receive message route from NowSMS to SMPP client but the problem is SMPP client receive message repeatedly (i sent only one message to gsm modem SIM card number but i receive that message many times from SMPP client).
Why this happen ? And how to fix this problem ?

Thanks,

Khanh

I have fixed this bug. The reason comes from my SMPP client. After receive deliver_sm, SMPP client needs to send response deliver_sm_resp back to SMSC so that it knows that message has been delivered.
