Hi, at sysmocom we are building a BTS (OsmoBTS, OpenBSC) test setup and use ofono to build our testcases. We are using Sierra Wireless (former Wavecom) modules and have some stability issues. I have two issues that I don't understand and they are related to the plugin model and after looking at others I don't find the answer. In the beginning we used the +WIND indication and created objects. E.g. we created the netreg after it starts to search for networks.. but if the +WIND indication fro the SIM ready came either during the registration or before.. we would see crashes. We now mostly ignore +WIND and guess about it. Not all plugins create all objects and they are created at different points. So what is the best way to do it? One other problem is that post_sim doesn't seem to be called. After looking at the src/modem.c file I see that it is only called for certain states. E.g. it looks like it is only called if the modem is still in the offline state and appears to be never called for us. Is there a way to debug it? E.g. when should the modem be powered up? when the SIM has been read? When the AT command interpreter is ready? kind regards holger
