Discovering services.

Based on the logs it was able to connect but it failed to discover the services.

The BLE peripheral is probably not configured properly.

Thank you for your reply
but i test it again.
Andoird(other ble debug app): conected ,discover the services write, read is well
IOS(LightBlue app): conected ,discover the services write, read is well
B4I(my test app): conected ,discover the services write, read is well
but only in android , my app is failed to discover the services , I'm not sure what the problem.

Check the unfiltered logs, there might be more information there.
