11.4.2 Reading Short Messages

Write	AT+CMGR=<index>
command
Function	Reads the short messages whose storage location is index from the
	preferred memory <mem1>.
Response	z When short messages are in PDU mode (+CMGR=0) and the
	command is successfully executed:
	[<CR><LF>+CMGR:
	<stat>,[<alpha>],<length><CR><LF><pdu><CR><LF>
	<CR><LF>OK<CR><LF>
	z In case of an error during command execution:
	<CR><LF>ERROR<CR><LF>
	z In case of an error related to the MS during command execution:
	<CR><LF>+CMS ERROR: <err><CR><LF>
	z When the index of the location to be read exceeds the maximum
	index of the SIM card: <CR><LF>+CME ERROR:
	<err><CR><LF>

Parameter description

<index>: integer, indicates the storage position of the short message in the memory.

<length>: integer, indicates the number of bytes in the TPDU.

<stat>: message type.

For messages in PDU mode (AT+CMGF=0):

z0: indicates messages that have been received but not read.

z1: indicates messages that have been received and read.

z2: indicates messages that have been stored but not sent.

z3: indicates messages that have been sent and stored

<alpha>: not supported currently

<pdu>: PDU. For details, see the AT+CMGL command.

Example 1:

Run AT+CMGR to read short messages.

Run AT+CMGR=1 to read the short message whose storage location is 1.

+CMGL: 1,,160

…(Short messages in PDU mode)
