Things are working okay if the signal strength is quite good. Nevertheless, if I alter the signal strength by for example removing the antenna, my device often comes into a strange state: For debugging I am using mainly "dbus-send" to see the current information about oFono. Sometimes the device is registered in the network, I have an IP adress and a fairly good signal strength (40-60). But doing a ping request does not work (no outgoing traffic), If I restart oFono manually, everything is working fine again. Is there any known bug regarding some blocking state changes or something like this? Are there known limitations using connman and oFono together?

By the way: I am using "ofono v1.30" and "connman v1.37". ^ permalink raw reply [flat|nested] 6+ messages in thread

I removed the antenna a couple of times (~30) to force the modem to lost the connection. Mounting the antenna again I retrieve a new IP address from the cellphone company. oFono is showing the information in the log and the settings of the network interface is updated (checked with "ip addr"). But occasionally (in case of failing ping), the address is shown but not applied to the interface. Therefore I wonder if it is really a oFono problem...
