So, my thinking is that we need to do something like this:
i) At telit_enable, set CFUN=1 and wait for QSS=2 or QSS=3.
ii) When we get QSS=2 or QSS=3 then we can set SIM_READY state so that
post_sim gets called... this should be called after all the IMSI
querying, etc. (right?)
iii) Once we're in SIM_READY state, we set CFUN=4... this is the 'end'
of the 'telit_enable' phase
iv) While in CFUN=4 state, we ignore QSS: 0
V) This should result in the GPRS interface being exported so that
connman can call 'online' call which will result in the switch to the
"real" CFUN=1
I gave this a try with the HE910 from Telit and the following works (not
in git format, this is just for reference... I will resubmit it later
after comment). Just note that it takes about 1 min for the SIM to
reach "ready" state after power up.
This also doesn't account for QSS: 0 occurring during 'offline' state...
need to check what happens there.
Comments?
