Hi there,

may I confirm
1. CYW20829 has features ULL and ACL, are they unique features or it's a BT standard?
2. CYW20829 PDM can support Microphone, does microphone can support long range 2.3km? Does it has reference design/application note
3. Why need ULL and ACL both features becuase ULL polling interval is 1ms faster than ACL 7.5ms.

Thank you!

Mason

Hello Mason @MasonPan,

After internal discussion, we can suggest you to check below ModusToolbox (MTB) sample code:

  1. BLE Voice Remote: in this code, you may check app_send_audio_data() in "app_bt_hid.c".
  2. BLE Long Range Central: central BLE role (scan for peripheral and initiate connection).
  3. BLE Long Range Peripheral: peripheral BLE role (advertising).

If you still have any doubts after checking, please kindly inform again.

Best regards,
Muhammad Nanda

Hello Mason,

For ULL and ACL:

For your question regarding PDM with long range, may you confirm do you mean application like this:

Dear Muhammand,

Appreciate your reply!

Yes, the PDM with BT long range to build a BT microphone for ideally 2.3km, is that doable? do you have resources/tools for reference?

 

Thank you!
