cyw920706wcdeval tx_test

Dear Sir

The code of "le_hello_sensor" is used in the modustoolbox and burned to the cyw920706wcdeval development board. The transmission power of the ble cannot be tested. The command "le_transmitter_test" executes normally. Classic Bluetooth "tx_test" can test that the transmission power is 9.55dbm.Please help analyze and answer this question.

thanks,

arthur

Hi,

Please boot the chip in pure Controller mode and try again.

When running with a code example, the chip will enter what is called Embedded mode. The RF will be occupied by the application and can't fulfill your test request.

Best regards

Hi 

Is it pure Controller mode when I use bluetool to send test instructions?

Best regards

Yes. Or burn the basic hcd file using chipload.exe can lead you to the Controller mode, too. See:
