Communication is Key

Keep Communication Open
The firmware and software teams need open lines of communication:

  • Discuss any changes to the GATT profile or spec.
  • Share funny or unexpected behaviors observed during testing.
  • Brainstorm ways to simplify or streamline communication.

Leverage the Right Tools
Bluetooth issues can be tricky to pinpoint. These tools will help you locate whether problems are on the firmware side or the app side:

  • nRF52 Dongle: A cost-effective and powerful BLE sniffer for capturing packets.
  • iOS Bluetooth Packet Logger: Perfect for debugging app-side issues on iOS.
  • HCI Logs (Android): Enable and extract Bluetooth logs on Android to trace low-level behavior.
  • 3rd Party Tools (e.g., LightBlue): Use apps like LightBlue to test your device independently of your app to isolate issues.

Why This Matters

Troubleshooting BLE issues often feels like finding a needle in a haystack. Logs and sniffers help you pinpoint where things are breaking down so you can fix them faster. At the same time, collaboration between firmware and app teams ensures everyone is aligned and working toward the same goals.
