I get the following linker error:
hci_audio_gateway.c:502: undefined reference to `wiced_bt_dev_read_tx_power'
I guess, it is the same problem as in WICED Studio - https://community.cypress.com/t5/WICED-Studio-Bluetooth/Bluetooth-20706-wiced-bt-dev-read-tx-power/t...
Is there any other way to read Tx power?
You can use CyBluetool to read Transmit power for BREDR.
For this API issue, yes its a linking error. I have created a ticket internally to fix this issue. Thanks for highlighting.
Sorry, but my question is about reading transmit power from the application running on CYBT module. Is it possible to read transmit power from the application running on CYBT module, without using external tools running on PC?
Unfortunately there is no other API to read Tx power in application. We will try to fix this error in next versions of BTSDK.
