How Send Binary Message (UserDataPdu) more that 256 byts

[mukul]

I am submitting binary messages (UserDataPdu) as following
here sTextHex is variable of my hex string

example:

foreach (SubmitSm sm in req)
{
sm.UserDataPdu = HexStringToByteArray(sTextHex);
sm.RegisteredDelivery = 1;
}
SubmitSmResp[] resp = Client.Submit(req);

when the length of sTextHex is less then 256 bytes it is running okay but when the length is more than 256 bytes it showing error

error:
Value was either too large or too small for an unsigned byte.


please help me about this

You need to split your byte array to parts with length <=140 bytes
and send them as concatenated messages.

thanks for your reply

but is there any way to submit long binary messages (UserDataPdu)

more than 224 bytes at once without splitting

is there any plan to add this feature to your library

please let us know

SMPP message_payload field allows to send 64K, but GSM standard limits one message to 140 bytes. Therefore most SMSC does not accept short messages longer than 140 bytes.

Yes, I make plans to add ability to send long bytes array as concatenated messages.

For PTV to work fully you need to have the other devices IP address programmed into your contact list or else it will not work
