Hi there! I understand that you're having some trouble with your Cardo Packtalk Edge not being recognized by the Cardo Connect app, even though your phone can connect for calls but not answer them. Let’s work through this together.

1. Check Bluetooth Settings:
- First, let's ensure that the Cardo Connect app has access to Bluetooth on your iPhone. Go to Settings > Cardo Connect and make sure that Bluetooth access is enabled.

2. Forget and Re-Pair the Device:
- Go to your iPhone’s Bluetooth settings and "Forget" the Cardo Packtalk Edge. Then, restart your phone.
- After the restart, try to pair your Cardo Packtalk Edge again as follows:
- Turn on your Packtalk Edge.
- Open the Cardo Connect app.
- Follow the instructions to connect your device.

3. Reset the Packtalk Edge:
- If it still isn't recognized, consider performing a hard reset on your Packtalk Edge. This usually resolves many connection issues. You can do this by turning off the device, holding down the + and *- buttons together until you hear a voice prompt, and then follow the prompts to reset.

4. Connection Check:
- After the reset, revisit the Bluetooth settings on your iPhone and ensure the Packtalk Edge is listed and connected. Then, try relaunching the Cardo Connect app to see if it recognizes the device.

5. Ensure App Updates:
- It’s also a good idea to check that the Cardo Connect app is updated to the latest version available in the App Store.

Do these steps and let me know if your Cardo Packtalk Edge is recognized in the app now. If you encounter any issues during these steps, feel free to ask!
