Sequence Number is not incremented when sending large SMS #50

Open oeil2lynx opened 1 year ago

oeil2lynx commented 1 year ago

For all the segments of an SMS longer than 140 chars, the sequence number is the same. It should not be. For some SMSC, the connection is rejected and re-binded and the SMS is not fully sent. It could give an Null Exception ins some case.

The sequence_number may range from: 0x00000001 to 0x7FFFFFFF.

There is no specific requirement on how the sequence_number should be set. However, it is recommended that the sequence number be a monotonically increasing number.
