12.8 AT+CMGW Write Short Messages to Memory
AT+CMGW execute and write commands transmit a short message (either SMS-DELIVER or SMS-SUBMIT) from
TE to memory storage <mem2>. Memory location <index> of the stored message is returned. Message status
will be set to 'stored unsent' unless otherwise given in parameter <stat>.
After invoking the execute or write command wait for the prompt ">" and then start to write the message. To save
the message simply enter <CTRL-Z>. To abort writing use <ESC>. Abortion is acknowledged with "OK", though
the message will not be saved.
Message Length in Text Mode: The maximum length of a short message depends on the used coding scheme
configured with <dcs> of AT+CSMP:
7 bit GSM coding scheme: 160 characters
8 bit GSM coding scheme: 140 characters
16 bit GSM coding scheme: 70 characters.
The length of 8-bit data coded short messages has to be greater than 0.
For more information on data coding schemes and character sets refer to 3GPP TS 23.038 [35] and Section
1.7.1, GSM alphabet tables and UCS2 character values.
