Samsung Galaxy Tab A8 does not work with nRF Mesh Android App

[Alex Ross]

Hello,

Not sure where to direct this (we can open a GitHub issue but wanted to clear it here first), basically everything works great on our Galaxy Tab S6 Lite (SM-P610), can provision, everything. Same for the iOS version. However on the Samsung Galaxy Tab A8 (SM-X200) can see the device to be provisioned, but fails to provision it after the first steps.

We're using the 833 dev kit with soft device 140.  

Thanks,

Alex

Hi again

So, I reproduced it on my end as well, and created an internal case on it with our mobile apps team. However, from my Ellisys sniffer trace, the error seems to be due to an unexpected packet length, which initially leads me to think it's related with the same specification breach we discovered earlier this summer. It is still strange that it only occurs with the nRF Mesh application on the A8 side. It seems to be related to some timing of tasks in the combination of A8 tab, nRF Mesh application, and nRF5 SDK. 

Our mobile app developers are starting to look into it, but I can't guarantee a patch/fix right away I'm afraid.

Hi,

Any updates on this? One of our clients just bought ~200 of these Samsung Tab A8 tablets...

Thanks.

Has your client also reproduced this issue, or are they yet to run into any problems. What version/revision of the A8 tablets have they purchased. Unfortunately we don't have any updates from our side on this issue.

Best regards,

Simon

Yes, our client is not able to provision our devices on the A8 tablets - that is how we first found out about the problem. We immediately purchased our own to confirm the issue. Neither our app nor Nordic's nRF Mesh app is able to provision devices on the A8. Works fine on the S6 Lite or older A7.

Our firmware is based on SDK17.0.2 + Mesh SDK 4.1.0.

Okay, thank you. Please contact the sales representative in your area if you want to escalate this issue internally, as I don't have any further leverage on my part. If you don't know how to get in touch with the regional sales manager of your area, you can do so by filling out our sales related questions form here.

Best regards,

Simon
