Should you use a third-party library for Bluetooth integration?

Should you use a third-party library for Bluetooth integration, or write it yourself? When deciding, don’t overlook this one thing:

Third-party libraries do solve real problems. They can abstract Android/iOS quirks, accelerate timelines, and handle common edge cases.

I’ve used them. They can be great!

But don’t overlook this:

Convenience often trades visibility for obscurity.

When you rely on a precompiled framework or an open-source project that you can’t easily debug, you’re forced to:

🔹 Work around hidden complexity
(e.g., Why does the library fail with this BLE device but not others?)

🔹 Accept optimization ceilings
(e.g., Can’t tweak packet sizes or retry logic for your hardware’s unique needs.)

🔹 Pray for updates
(e.g., When you need new device support or a critical bug fix, how long until the library catches up?)

Owning the code isn’t about reinventing the wheel. It’s about:

✅ Clarity
Trace disconnects to OS timeouts, incorrect API usage, or vendor protocol oddities.

✅ Precision
Add telemetry for your use case (e.g., latency thresholds for medical devices).

✅ Strategic agility
Support new hardware without waiting for a maintainer’s roadmap.

This isn’t an anti-library rant. Use them for prototypes or non-critical features. But for apps where reliability defines your product (and reputation), my take is:
Deep ownership isn’t optional—it’s strategic.

What’s your take?
Have you seen teams regret (or rejoice over) this decision?
