Hi,

I prefer to use this module(BR/EDR mode) in our design using HCI mode where a main MCU will send the commands over UART. In that case please advice whether it's possible to implement below functionalities without flashing the application/firmware to the module. If not please briefly explain the steps or suggest additional readings to implement these.

  1. OOB pairing using NFC
  2. TX power setting

I found this HCI control guide in the forum but it doesn't have any commands related to setting TX power or OOB pairing.

Regards,

Se

Hi SaEa_4705941​,

1. There are standard HCI commands related to OOB pairing, please check BT core spec for more details. However, we have not tested OOB functionality at our end. Also, we do not have a specific code example for reference, please check BTM_PAIRING_IO_CAPABILITIES_BLE_REQUEST_EVT in demo.hello_client example in WICED SDK.

2. You can use Vendor Specific command for this. You will need to connect your device to peer device using HCI command and then use set tx power vendor specific command for setting the tx power. Please refer- CYBT-423028-02 BT module (CYW20719 radio): How can transmit power be controlled?

Please refer Configuring Transmit (Tx) Power on CYW20706 Chip - KBA228573 for more details about CYW20706 tx power.
