i have a similar issue - the connectivity-API will try to connect to the device- which does, however, not have any address information:

using the latest mdslib-1.6.0(1)-release

UPDATE: i get the same exception when using the connectivity-API sample application ...

[Karol Baran]

Hey. ConnectivityAPI should be almost copy / paste from Android Example App. Unfortunately I'm not the author of this sample and looks like something is missing.

I will check this.

[Łukasz Haraźny]

@Karol_Baran Do you have some update about this issue?

[Petri Lipponen]

@martin-vl Your log shows that you are using really old firmware on the sensor (0.6.0). There have been some changes with the /Info response since then and the new connectivity code does not support the old format. Please update your sensors to the latest suitable app using the sampleapp. You can find the update packages in here. Just choose the sample app you want on the sensor. In case you have your own app, please update to the latest movesense-device-lib, since there are a lot of fixes and changes.

[Michal Szynkaruk]

Looks that this is an old issue which shouldn't be any longer valid. Closing issue.
