Hi,
I am using an eUICC SIM which requires SIM Application Toolkit must be activate on the module.
I check AT^SSAT? and get a response that state is 1 (OFF). Does that mean the current mode is 0 (AR mode)?
Also, I cannot find any AT command to activate/deactivate the SIM Application Toolkit. Can I assume that the SIM Application Toolkit on the module is automatically activated?
Hello,
In read mode the AT^SSTA? command returns the <state> as first parameter which may be 1 (off) or 2 (idle). But in the write mode you configure the parameter <mode> as first parameter which can be 0 (Automatic Response (AR) mode) or 1 (Explicit Response (ER) mode).
In AR mode the module enters the OFF state (<state>=1) after restart and in ER mode the module enters the IDLE state (<state>=2) after restart.
So to switch to the ER mode you need to enter AT^SSTA=1 and restart the module. then when you ask AT^SSTA? you will get 2 as first parameter.
Example:
at^ssta?
^SSTA: 1,0,1,"FFFFFFFF7F9D00DFBF00001FE2000000034B000000000000000000000008",300,2
OK
at^ssta=1
OK
at+cfun=1,1
OK
