Hello ofono mailing list,
I'm wondering what ofono puts in the directory "var/lib/ofono/".
On my embedded device, I can see these directories:
- var/lib/ofono/228014420910471
- var/lib/ofono/228014420910471-3
The number 228014420910471 is the IMSI of my simcard right ?
Yes
In the first one (228014420910471), I can see 3 files called gprs,
netreg and sms. And there are some configuration in it. It's pretty simple.
In the other directory, there are 4 files (4f20 6f46 6f49
version). But I don't understand theirs purposes. Maybe these are SMS
files ? Why the directory is named <IMSI>-3 ? Other directories with
another number can be created ?
This is the oFono cache for SIM filesystem files. Essentially files
that are not writable by the user on the SIM are cached on the
filesystem to speed up initialization time. The suffix (e.g. -3) is the
SIM phase. E.g. 3 is 3G/USIM, 2 is 2G/SIM.
I'm wondering this because I want to put this directory and files in a
separated partition of 1.3MB and put my root partition read only. So I'm
trying to figure out if it's enough, what kind of files ofono will write
in it, when and the frequency (it's a NOR flash partition and I would
like to known if it's a good idea). As I understand, ofono uses this
directory to store SMS also. But, what kind of SMS ? All the SMS I try
to send ? All the SMS I received ? I began to read the source code but
maybe you can tell me some hints.
oFono caches both incoming and outgoing SMS here as well. For
reception, the SMS store is used to cache reception of multi-part SMSes,
e.g. ones longer than could fit into one payload. For outgoing, the SMS
is cached here until it has been sent / delivered.
