readRSSI on Android 7 does nothing

[Gueoff]

Version

Tell us which versions you are using:

• react-native-ble-manager v7.3.1
• react-native v0.61.4
• Android v.7.0

Expected behaviour

The method reads the peripheral RSSI and returns value between -1 & -80

Actual behaviour

The method does nothing and never stops

Steps to reproduce

1. Launch connect function.
2. Launch readRSSI function

Stack trace and console log

Call in my app:

console.log('before');
await BleManager.connect(identifier);
console.log('between');
await BleManager.readRSSI(identifier);
console.log('after');

Method called in the module:

readRSSI(peripheralId) {
    console.log('readRSSI module method');
    return new Promise((fulfill, reject) => {
      bleManager.readRSSI(peripheralId, (error, rssi) => {
        console.log('result', error, rssi);
        if (error) {
          reject(error);
        } else {
          fulfill(rssi);
        }
      });
    });
  }

I have tested the code bellow on few devices, on my Android 7.0, stack traces are :

before
between
readRSSI module method

on other devices:

before
between
readRSSI module method
result null -54
after
