Failed getting composition data after app update to 2.1.0

[torstenbofink]

Hi,

We are using nrf52 dev boards running mynewt and until two days ago we could use the app to identify/provision and get composition data for nodes and get composition data from them. After the update to version 2.1.0 of the android app, it hangs while obtaining composition data, see attached screenshot.

The release notes say something about fixing problems related to composition data. Maybe something was fixed and a new problem introduced?

Hi Torsten,

Could you give some more information on the firmware you are running on the nRF52 ? 

Could you capture a sniffer trace of the provisioning process ? 

After the issue happens, do you see the device advertising as a proxy node ? Can you do the configuration after that ?

I'm looking at the output log and see that we get a request for the composition data, we get a request for page "255", which seams to cause the error. Why is it requesting for this page, should it not be 0?

Hi @kolten, sorry for the delayed reply. I did give this a go. Looking at the logs I see a slight issue here. Everytime when we send the first CompositionDataGet message, the very first segment is not sent by the firmware side (what's received is from the 1st to 5th), but the second time we send a CompositionDataGet it sends all the packets(from 0th segment to the 5th). I will also debug more on my end to see why the 0th segment is not resent.

I can confirm the issue is on our end, this was indeed based on a fix madee for an issue related to sequence number validation.

I have uploaded a newer version to the play store and it should up in a couple of hours. In the mean time you can find the latest apk on Github as well. Thanks for reporting this issue and for helping us with the provided fws. Hope this fixes your issue. Let us know if I can be of more help.
