|
|
* The STK atom is only useful after SIM has been initialised,
|
|
* so really it belongs in post_sim. However, the order of the
|
|
* following three actions is adapted to work around different
|
|
* issues with the Calypso's firmware in its different versions
|
|
* (may have been fixed starting at some version, but this order
|
|
* should work with any version).
|
|
*
|
|
* To deal with PIN-enabled and PIN-disabled SIM cards, the order
|
|
* needs to be as follows:
|
|
*
|
|
* AT%SATC="..."
|
|
* ...
|
|
* AT+CFUN=1
|
|
* ...
|
|
* AT+CPIN="..."
|
|
*
|
|
* %SATC comes before the other two actions because it provides
|
|
* the Terminal Profile data to the modem, which will be used
|
|
* during the Profile Download either during +CFUN=1 (on
|
|
* unprotected cards) or +CPIN="..." (on protected cards).
|
|
* The STK atom needs to be present at this time because the
|
|
* card may start issuing proactive commands immediately after
|
|
* the Download.
|
|
*
|
|
* +CFUN=1 appears before PIN entry because switching from +CFUN
|
|
* mode 0 later, on the Calypso has side effects at least on some
|
|
* versions of the firmware:
|
|
*
|
|
* mode 0 -> 1 transition forces PIN re-authentication.
|
|
* mode 0 -> 4 doesn't work at all.
|
|
* mode 1 -> 4 and
|
|
* mode 4 -> 1 transitions work and have no side effects.
|
|
*
|
|
* So in order to switch to Offline mode at startup,
|
|
* AT+CFUN=1;+CFUN=4 would be needed.
|
|
*
|
|
* Additionally AT+CFUN=1 response is not checked: on PIN-enabled
|
|
* cards, it will in most situations return "+CME ERROR: SIM PIN
|
|
* required" (CME ERROR 11) even though the switch to mode 1
|
|
* succeeds. It will not perform Profile Download on those cards
|
|
* though, until another +CPIN command.
