Wi-Fi Combo

Hi,

Are there any WiFi+BT combo modules meeting following specification:

- WiFi, BT and BLE

- module should have its own MCU

- external antenna (i.e. module itself should only have a pad, which would be connected to antenna on our main board)

- Bluetooth profile HFP AG (Audio Gateway)

- (Bluetooth profile AD2P)

- I2S interface (for audio)

- UART interface (for communication between module and main CPU of the host system)

Best regards,

Pekka

Hi Pekka,

CYW943907WAE3 chip supports A2DP, HFP profile. Both the 43907 and 20706 have their I2S pins directly connected to the codec. This can be one of the options you are looking for.

FYI, CYW43438/CYW4343W supports A2DP, HFP is not supported. PCM is used for audio interface, not I2S.

CYW43012 supports A2DP (source) but uses UART transmission.
