You're not. When something in bt doesn't work it's caused by two things: a regular bug in the stack, or a feature of the spec that was implemented incorrectly which comes from ambiguous wording in the spec or simply the fact that it's several thousand pages long. This is usually not a problem if you have two devices using the same stack talking to each other but normally that's not the case.
- byteflip 4y ago100%. Interoperability is the complexity. You’ll find old popular devices for example that are slightly different in behavior to the “norm”. It could be straight up incorrect behavior or maybe something more subtle. Do you drop support for those devices or change your behavior dynamically based on the device? Would your customers complain if you did drop it? Can you identify the device reliably? What if they update their software/behavior in the future - would your workaround break? Does your BT software stack even give you enough control to do fix it? Does your hardware/software vendor give you enough support to fix things if you can’t do it yourself? How many other devices did you test against? It was painful but fun to work on.
