| * 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. |
