Re: [PATCH 3/3] doc: Add SystemPath to Modem interface
Hi, + string SystemPath [readonly, optional] + + String giving a consistent hardware path for the modem + device. It will not change in case of reboot of modem + or ofono. Given that many modems are USB devices, I don't think you can actually promise this. I can envision a (slightly pathological) hardware design whereby the presence or absence of an _external_ device at startup may change the device enumeration order and thereby the syspath... Right, this can depend on the kernel version also. I wouldn't claim any guarantees at the D-Bus API level as it is outside our control. If someone chooses to use it as a consistent path, then they do it at their own risk. Regards, -Denis ___ ofono mailing list ofono@ofono.org https://lists.ofono.org/mailman/listinfo/ofono
