[Android] Connect and discover services - BleError: Device 00:16:A4:4C:B9:6A was disconnected

Prerequisites

Please answer the following questions for yourself before submitting an issue.

• I am running the latest version
• I checked the documentation and found no answer
• I checked to make sure that this issue has not already been filed

Expected Behavior

Should be able to connect and discover services

Current Behavior

Receiving a disconnection error with status code 61 when trying to connect and discover services for a BLE device using an Android phone. The way I have designed my code is that when I receive an error in connection request from react-native-ble-plx library I again try to connect to the BLE device in a loop for 5 attempts, if all the 5 attempts result in error on 6th attempt I pass refershGatt param with value onconnected to the connect call. This does clear the cache and I am able to connect to the device but the service descriptions are empty. The device I try to connect uses Bluetooth dongle so the dongle might be paired to the Android phone in a previous attempt so when I manually unpair/forget the Bluetooth dongle from the paired devices list it does successfully discover the services. I am expecting to connect to the BLE device without manually unpairing the BLE dongle from the paired devices list in the android phone.

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Connect to a device using Bluetooth dongle

bleManager.connectToDevice(deviceId)

1. Then discover the services and characteristics

bleManager.discoverAllServicesAndCharacteristicsForDevice(deviceId)

1. Disconnect from device

bleManager.cancelDeviceConnection(deviceId)

1. Connect and try to discover services to a different device using the same Bluetooth dongle but pass refreshgatt parameter with the connect request.

bleManager.connectToDevice(deviceId, { refreshGatt: 'OnConnected' })
