Hello,

We are developing CYBT-483056-02 with MTB2.2.

On CYBT-483039-02 with CYW20719B1, it was necessary to add the following settings in WICED.

Do I need to make similar settings when developing CYBT-483056-02 with MTB?

Should I set the output setting of CYW20719B2 to -2dBm (because PA / LNA is 22dBm) in order to obtain POUT of 20dBm?

* Refer: https://community.cypress.com/t5/Resource-Library/Change-List-CYW20719-B1-and-CYW20719-B2/ta-p/24641...

 

Best regards,

TK

Hi,

The background to this question is as follows.

-In the design using CYBT-483039-02 (CYW20719B1) and WICED, it was possible to connect to the opposite terminal.

  At that time, PA / LNA is enabled according to the following.

  https://community.cypress.com/t5/WICED-Smart-Bluetooth/CYBT-483039-02-documented-PA-LNA-control-inte...

-Using CYBT-483056-02 (CYW20719B2) and MTB, the above PA / LNA is also enabled, but I cannot connect to the opposite terminal.

  When I check the RSSI, there are variations, and I'm guessing that PA / LNA is not enabled.

 

Please tell me how to operate normally with the combination of CYBT-483056-02 and MTB.

 

Best regards,

TK
