Samsung Galaxy A8 does not detect beacons

OscarCanek commented 6 years ago

Prerequisites

[ ] Put an X between the brackets on this line if you have done all of the following:
- [x] My beacons have Estimote Monitoring enabled
- [x] My Android device/devices supports BLE and has Android OS version >= 5.0.0
- [x] My Android device/devices have bluetooth enabled
- [x] My app has Location Permissions granted

Basic information

Estimote SDK version: 1.0.0, 0.5.1

Android devices affected: Samsung Galaxy A8. Model number: SM-A530F

Android OS version affected: 7.1.1

Beacon hardware version: F3.3

Description

The onEnter and onChange events are not triggered in a Samsung Galaxy A8

(Optional) Steps to reproduce:

Create the observer
Create the zone
Start the zone observation
Put the cellphone inside a beacon range

Expected behavior: Trigger the onEnter/onChange event when the phone is inside the beacon range

Actual behavior: It won't trigger any event when the phone is inside the beacon range

Only works if I leave enabled the telemetry at the SDK. In other words, on our Samsung A8 the beacon detection only works if you don't put the withTelemetryReportingDisabled at the proximity observer

I have this problem too.

Estimote Proximity SDK version: 1.0.3 Android devices affected: Samsung Galaxy A8. Model number: SM-A530F Android OS version affected: 8.0.0 Beacon hardware Revision: J1.9_B1.1

With Telemetry disabled I cant see any beacons (but the same code works fine on e.g. a Galaxy S8). As soon as I enable Telemetry, the beacon shows up in my app on the Galaxy A8.

Im not sure whether it is relevant to this bug, but i noticed in my logcat that the TelemetryReporting feature seems to start 8 separate scanners in addition to the Proximity scanner:

If I restart my app (or just restart my scanning logic) this then very quickly leads to the error: BtGatt.GattService: App 'my.app' is scanning too frequently which is also mentioned in this issue: Issue 48 If I disable Telemetry Reporting using withTelemetryReportingDisabled(), only one scanner is started and I am free to restart the scanning a handful of times before I still eventually get the "is scanning to frequently" error.
