An example dealing with multiple write requests would be very helpful

Hi,
I am a JS noob and would really appreciate a sample demonstrating how to implement queuing or retries for writeValue requests. I get "NetworkError: GATT operation already in progress." (i.e. https://github.com/WebBluetoothCG/web-bluetooth/issues/188) when trying to write a non-trivial app that has user driven writes.
