Re: [Zephyr-users] [Zephyr-devel] DTM mode on nrf52840

The shell application takes console commands, what you need is HCI Test mode over UART.
On a nRF52840,you will need to use both the UART instances, one for console and the other for a HCI "tap" or basically the HCI_RAW. Or not use console over UART and use one instance for HCI, which is nothing but a hybrid of hci_uart sample and your application.

Thanks for the responses.
Permit me to clarify
1.Carles: what you suggest might be what I am looking for- the ability to have a standard host+controller on the nrf52, and the additional ability to tap into DTM when needed. That way, I only need only image on the nrf52, and can pre-program the ICs. I am, however, using the uart shell already - can the DTM shell co-exist? Does it expose an HCI interface? I’ll take a look and get back to you.
2. Vinayak: I exposed an h4 over uart as a controller ONLY. I did not get it working with the application- this was a separate project/attempt. If the transport is virtual, I don’t understand how Carles’ suggestion works- could you help me understand ?
Perhaps a better Question would have been - j have a host+controller implemented, and would also like DTM over H4 for factory testing - how would you suggest I do that?
Thanks to both of you.
