I have been trying to use various of the api calls that are defined in the headers but are not directly exposed as part of the arduino ide - I noticed that a lot of the most interesting ones for me seem to be missing from the firmware.
I plan to use the ones that control the power management to check the battery level and trigger the power-off and restart calls. kaktus.martin over in the SIM-Card thread also found non-included APIs regarding Sim Management.
Is this a problem of the firmware that is used with the Arduino ide? Would switching to the eclipse IDE and the alternative SDK help?
Being able to check the battery level and schedule Wake-ups by time would really help with my project (I would have to externalize that to a second micro otherwise).
