androidthings / robocar Goto Github PK

I am using NearBy 2.0 API version 'com.google.android.gms:play-services-nearby:12.0.1' with android things'com.google.android.things:androidthings:1.0'to create a smart home app, but previously upto 8th may it was working fine with the build downloaded from android things console , but from yesterday it is throwing com.google.android.gms.common.api.ApiException:8007 STATUS_BLUETOOTH_ERROR. when i am starting advertisement or discovery whichever maybe. But if I use the previous build(image with apk) of 8th may it is working fine . I tried with that old apk also like new os image with old apk , found not working. In logcat i found it is unable to start listening for incoming connections. I searched SO and google a lot but no solution worked. Even followed this https://stackoverflow.com/questions/46036191/error-codes-in-nearby-connections-2-0/46328410 but no luck. I am using Raspberry PI 3 model B. Help!!
