Question

Hi,

I would like to read incoming SMS in PDU mode. (non English). I use the following command to list all incoming SMS:

root@TRB140:~# gsmctl -S -l all

and this is what I get:

Index: 3

Date: 2020-03-17 10:10:24

Sender: +972526726565

Text: ▄▄▄▄

Status: read

------------------------------

or:

root@TRB140:~# gsmctl -S -r 3

Index: 3

Date: 2020-03-17 10:10:24

Sender: +972526726565

Status: read

Is there a way to list and read incoming SMS in PDU mode?

Thank you.

Michael

Hello.

Yes it is possible, I checked and it works.

To read SMS in pdu mode, you must use the command : gsmctl -A AT+QSMSR

I used this converter to convert from PDU to text format.

Hello,

Thank you for your answer. I tried this command:

gsmctl -A AT+QSMSR=?

and got this response: +QSMSR: <index>[,<opmode>]

I tried this command: 

gsmctl -A AT+QSMSR=3

and got the response "OK"

Can you please tell me what am I doing wrong? I don't get the incoming SMS in PDU mode.

Thank you.

Hi,

I am able to read incoming SMS using this command:

"gsmctl -A AT+QSMSL=4" 

You may close the case.

Thank you.
