21. BLE Test Method

Direct Test Mode(DTM)

135

There are three ways to test BLE DUT as follows.

21.1 Direct Test Mode(DTM)

DTM is a standard mode in the BLE 4.1 specification (Vol 6, Part F) that allows testing of the radio's Phy

sical Layer (PHY) by transmitting and receiving sequences of test packets. This is often used in complian

ce and production-line testing, without the need of going through the complete BLE Protocol Stack, i.e.

it skips the Host Stack and talks directly to the radio in an isolated manner.

Another layer in the BLE specification is the

Host Controller Interface (HCI)

- a standard-defined interfac

e to exchange data between the BLE Host Stack and the radio Controller.

In Direct Test mode, the test packets required for DUT are sent to MTP200B and DUT through HCI or 2-

Wire UART interfaces, and the received packet counts are reported.

There are two test methods for Direct Test Mode.

Test through HCI Interface (UART or USB)

Test through 2-wire UART Interface

Figure 21-1

Direct Test Mode Setup : HCI Interface(left), 2-wire UART Interface(right)

MTP200B supports UART HCI and 2-Wire UART required in BT LE Direct Test Mode.
