How can I make the DTM support HCI commands

[Tao]

Hi

My product is ready for mass production, before start to sell, we need to do the Bluetooth qualification, we asked several local test labs, they told us that their test system don't support DTM command(Two wire protocol), and only support HCI command, for example, the RESET command should be 0x01030C00, not 0x0000, any example for reference?

Thx

The Bluetooth core spec states that it's required to implement one of the two optional Direct Test Mode interfaces. Nordic has code for the UART based Direct Test Mode in the SDK and you can read more about it here.

So regarding HCI code, we don't have any available, but test houses would normally have equipment for both optional test interface implementation.
