Keep receiving the samme SMS from the network

[henry64]

Hi

I'm expirencing  a very strang thing, I keep receiving the same sms over and over again. Do you have any clue why that happens?

It's like the network have not received an ACK for the SMS so it keeps trying to deliver it.

Hello

Thank you for your information.

Please try send acknowledgement in sms event handler:

procedure TForm1.nrGsm1SmsReceived(Sender: TObject; aMem: String;
  idSms: Integer; aSms: TnrPduSms);
begin
  nrComm1.SendString('AT+CNMA'#13);
end;

Let me know if it helps, we will change built in driver.

Hi Roman

Well it actually stops the problem, I leave it up to your to decide if that's the right way to implement it - I have no clue  :-X

Hello

Thank you for your information.

We will fix this problem in the next release nrComm Lib (this week).

This ACK also solves the problem that I only got a delivery report on the first sms sent, for all successive sms's I got no report.

Please try
nrComm1.SendString('AT+CNMA=0'#13);
