cybt-343026-eval empty scan result

[Pavel]

Hi. We need to use cybt-343026-01 as a regular bluetooth module on arm board.

Currently we upload empty Modus Toolbox project using patchram utility via HCI UART.

But scanning does not work. Neither 'hcitool scan' nor 'hcitool lescan' returns non-empty result.

Is there specific code should be added in project?

[Owen_Zhang123]

Are you using the device as a bluetooth controller?

[Pavel]

yes

[Owen_Zhang123]

The device is mainly used in embedded mode. The controller mode is for test and certification usage. IFX will not support if you are using the device with other host stack. 

[Pavel]

How to add the ability to work with this module in controller mode?

Is it possible to upload (and run) project to controller via hci uart without pulling spi_mosi down?

[Owen_Zhang123]

Please refer to the following blog about how to run the device in HCI mode.

[Pavel]

uploading EmptyWicedBluetooth_download.hcd does not solve problem. Scanning does not work

[Owen_Zhang123]

Could you receive the response after you send the scan command.

[Pavel]

Response is empty. No devices found

[Owen_Zhang123]

After you send the scan enable command, there should be a command complete event. Please check if you receive the event. Then you can receive event about the device found.

I download an empty project to the device and send reset, scan enable with cybluetool. Then I can see the adv devices. Please check the log below.

I also attached the .hex file for you.

How this can be achieved with "EmptyWicedBluetooth" app instead of "HelloSensor"?
