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
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.
