I have two questions for now-

1. As per CYBT-413034-02 datasheet,

TX current consumption

BLE silicon: 5.6 mA (MCU + radio only, 0 dbm)

RX current consumption

Bluetooth silicon: 5.9 mA (MCU + radio only)

Why is RX current greater than Tx current?

2. Which kind of BT audio phones can be used with CYBT-413034-02.

Please name few companies and their part numbers. Is there any example

code to demonstrate BT audio communication. (Yes I know there are only

few audio profiles which CYBT-413034-02 supports).

Hi,

In General the Rx current may be more than Tx current. Because receiver part will be having amplifier + filter circuits etc which may lead to comparatively greater current consumption on Rx side.

CYBT-413034-02 can be connected to any phones which have Bluetooth support. But it doesn't support all Audio profiles.

It supports only A2DP source ( WICED Bluetooth Software Features  - refer to 20719 features listed) .

watch demo example in WICED SDK uses A2DP source  ( /20719-B1_Bluetooth/apps/demo/watch ) .

Thanks,

Anjana
