This page contains my (personal) notes on how Telepathy (and to some degree rtcom) works, in general, and how it works on Fremantle, and how we plan to make it all work.


Accounts are stored in /home/user/.rtcom-accounts/accounts.cfg on Fremantle, and HOME/.local/share/telepathy/mission-control/accounts.cfg normally in Telepathy.

It looks like Telepathy mission-control (MC) is the one that actually manages the accounts, and mc-tool can be used to manage the accounts. This means that likely there are no other tools that read accounts.cfg on Fremantle, and everything that lists/adds/removes accounts goes through Telepathy MC.

telepathy-ring accounts

It is not clear to me what adds the initial "sms" account, but there must be something that configures this account initially.


Fremantle logs using the rtcom-eventlogger package, to a SQLite3 database stored at /home/user/.rtcom-eventlogger/el-v1.db - all communication related events end up here.

The actual logging to the database is done (as far as I understand) by several different processes: rtcom-call-ui and rtcom-messaging-ui. These both interface with telepathy and log to the database as appropriate. (This is visible by looking at /proc/pid-of-program/fd on Fremantle - it will show that both programs have a fd open to the database)

Telepathy does come with a program called "Telepathy Logger" which can log to various database formats (and I guess just log all messages), and it also provides a way to read (not just write) log events. I am not sure if this is useful for us, but we could take a look later. For now, I believe our replacement programs for the call and messaging UI will have to log on their own.


telepathy-ring is used to communicate with the modem through ofono. This account has the following options set on my device:


ConnectAutomatically seems to suggest there is no specific program that starts telepathy-ring (just MC itself), as long as the account is requested (I guess?) by something.
