Gsm send sms Validity byte

Hi, I try to send sms with "gsm send sms" command. The command working properly but the byte "Validity" into the PDU created is set to 5m. I would set this byte to 0, how I can set this option?
Thanks

Hi,

Sorry, you cannot change the "Validity" value.

Best regards

Hi,

Sorry for my mistake. If you want to change the validity period when send sms. You can use command below:
gsm send pdu <span> <PDU codes>
but you need to encode your sms to pdu codes by your own.




More information about sms and pdu, please refer to www.openvox.cn/pub/misc/GSM%20Gateway/SMS_PDU_Mode.zip
Wish this will help you.

Best regards

thanks for prompt reply.
