BLE Radio: DTM and HCI


Direct Test Mode (DTM)

A mode to test the PHY by transmitting or receiving a sequence of test packets

Typically used for radio compliance testing and production-line calibration

PSoC 4 BLE enables DTM via the Host Control Interface

Host Control Interface (HCI)

An interface to exchange data between the BLE Stack and the Radio 

PSoC 4 BLE implements HCI over a UART interface to enter the DTM

PSoC 4 BLE simplifies RF compliance testing and calibration by providing a DTM over a UART interface
