Hi Julien,

 

in liblwm2m.h:

 

#ifndef LWM2M_EMBEDDED_MODE

#define lwm2m_gettimeofday gettimeofday

…

#else

int lwm2m_gettimeofday(struct timeval *tv, void *p);

…

#endif

 

So we implement our own  lwm2m_gettimeofday. Currently our implementation has more the

sematic of „uptime“ then „datetime“. „datetime“ will require a RTC (battery buffered,

or GPS based, or …). And, though the time is mostly used as timer, a datetime will bring

problem assuming, that the datetime is corrected from time to time. So we decided to use

the uptime.

 

Mit freundlichen Grüßen / Best regards

 

Achim Kraus

Hi,

I'm working again on porting wakaama on ARM MBED LPC1768

I know Achim & Jörg ported wakaama on a similar platform do:

How do you solved the "gettimeofday" issue.

In the online IDE (I think it's using the Keil  compiler) there is no gettimeofday implementation.

But if I export it to gcc and compile it on my PC, I get a gettimeofday implementation.

How do you solved this problem?
