isConnected not working when i get gatt 133 error

[MikhailNatalenko]

When my ble device disconnects me i get the gatt status 133. BleGattCoroutine throws an exception com.beepiz.bluetooth.gattcoroutines.OperationFailedException as expected, and then i want to check BLE status with isConnected() method. In this situatuion i expect 'false' but i get 'true'. Is it a bug?

I am sorry but I can't provide you a minimal sketch right now i do something like:

try{
    gatt.connect() 
    // ...Do all preparations
    //turn off ble device for example 
    gatt.readCharacteristic(characteristic)
} catch (e: Exception){
  if (!gatt.isConnected()) doSomethingWithError() // i expect that doSomethingWithError() will happend
}

The 133 error is quite obscure (it's named GATT_ERROR in AOSP, but undocumented, and when it happens, your best bet is to close the connection and retry from a new one. You should get the OperationFailedException or the other errors BleGattCoroutines can throw, and from the status present in the exception, handle the 133 to retry after closing the connection.
