Flash message in EC25

Hi all. How to send and receive flash message in EC25?

To the best of my knowledge, incoming flash SMSs are not treated any differently from non-flash, as far as the modem itself is concerned.

To send SMSs as flash (class zero, immediate display), simply set the Data Coding Scheme to 0xF0 (240 decimal). See 3GPP 23.038, section 4.

In text mode, you can do that with the AT command AT+CSMP=17,167,0,240

Change the “240” to “0” in that command to turn flash off again for sending.

Hi John,
Thanks for the information.

Hi @dhanagopal

Qnavigator tool can automatically complete some processes, such as sending SMS. You only need to fill in the receiving number and the content, then it will automatically send a series of AT commands for your referrence.
