Obtaining SMS delivery and confirmation with H5 modem

QUESTION: How do I obtain message delivery and confirmation when sending SMS through the H5 products?

On previous products, the AT+CNMI=3,2,0,1,0 command was valid and worked but it does not work with the H5 modem. The parameters are a bit different in the H5 modem.

Set the following commands:


The first value of +CSMP (49) requests the Status Report and Validity Period.

The fourth value of +CNMI (1) requests the +CDS status report.

If this does not work in your situation, then contact Multi-Tech for further support.
