QUESTION
I have an app that communicates with a bluetooth device, and I'm trying to replace that app with some code.
I tried using C# InTheHand nuget, Microsoft's Bluetooth LE Explorer, python's sockets and others to send data and see what happens.
But there's something I still don't understand - in each way using different libraries I saw in wireshark a different protocol: ATT, RFCOMM, L2CAP...
When I sniffed my bluetooth traffic from my phone using the app mentioned before, I saw mostly HCI_CMD protocol traffic.
How can I choose the protocol I want to send? Is there a simple package for that? something to read?
Do I need to build the packet myself? including headers and such?
Thank you!
Update:
Using Microsoft's Bluetooth LE Explorer I was able to send a packet that lit up my lamp, starting with 02010e10000c00040012(data)
Using bleak I was able to send a packet starting with 02010e10000c00040052(data)
the difference makes the lamp not ligh up and I'm not sure if I can change it via bleak as it's not part of the data I send
ANSWER
Answered 2021-Jun-14 at 18:48I think what you are showing is that bleak does a write without response while MS BLE Explorer does a write_with_response.
Looking at the Bleak documentation for write_gatt_char that seems to be consistent as response is False by default
write_gatt_char Parameters:
char_specifier (BleakGATTCharacteristic, int, str or UUID). The characteristic to write to, specified by either integer handle, UUID or directly by the BleakGATTCharacteristic object representing it.
data (bytes or bytearray) – The data to send.
response (bool) – If write-with-response operation should be done. Defaults to False.
I would expect the following to have the desired effect:

QUESTION
I have a custom lit web component that contains an element inside its Shadow DOM. I want to react to the change event fired by the input outside the custom element, but the change event has by default composed: false, so the event doesn't pass through the Shadow DOM boundary. I could catch the event inside my component implementation, but the composed property is read-only, so I can't update it and dispatch the same event object. I could create a new object with new Event('change', {'composed': true}), but then it doesn't have the properties like target of the original event. What's a good approach? Should I manually copy the original event's properties to the new event object?
ANSWER
Answered 2021-Jun-08 at 06:45It's not possible to dispatch a single Event instance more than once, so even if you could modify the composed property of the original event you couldn't redispatch it anyway.
So you need to create a new event to dispatch from your custom element, but the details of how exactly you want to create the event and what it should contain will probably depend on your use case. I'd suggest to try to keep it as simple as possible and make an event that includes the information you need and then dispatch it.
There's probably a reason why the native change event is not composed, but you can simulate propagating it out of your custom element by creating an event with the name change and dispatching it from your custom element. You probably don't even need to use composed in most cases as just dispatching it from your custom element (this) makes it available in the parent scope (one level up from your shadow root) which is where the event probably should be handled in most cases.
The fact that you have an in your shadow root should probably be treated as an implementation detail (at least in some cases) and not exposed outside unnecessarily, but when you do need to expose it directly, you can make it available e.g. as a property on your custom element (which could then be accessed from your custom event) or you can include a reference to it in the event object (e.g. in detail property of CustomEvent or a property of a custom event class).
For example here's how Vaadin components like propagate the change event:
