MT8850A / MT8852A Bluetooth Test Set Getting Started
Running a Script in Standard Mode
In Standard mode, the MT8850A/MT8852A uses full Test Mode signalling and all the
defined test controls to test the EUT in the fastest and most efficient way possible.
Standard mode is the default mode setting, although it should be noted that for devices
with only a limited implementation of test mode functionality, operation in standard mode
may result in the EUT dropping the link or failing to respond to commands from the
MT8850A/MT8852A. In this case, select single payload or null packet operation.
Running a Script in Single Payload Mode
Single payload mode uses Test Mode signalling but in a very restricted manner. This is
ideal when the test device does not yet have a full Test Mode implemented, and the
repetitive signalling in standard mode may cause it to fail or drop the link. When the user
selects to run a script in single payload mode, a message to this effect displays on the
uppermost line of every page to remind the user that a mode other than standard is
currently selected.
In this mode, the user can define the packet length, packet payload, and set loopback or
TX mode and hopping to on or off. The MT8850A/MT8852A then sends a single test
control to put the EUT into the specified state, and no further test controls are sent. When
the customer views the measurement screens, only measurements that can be made on
the selected packets are presented.
If single payload mode is selected, an additional “single payload edit” line displays on the
screen.
1. Move the cursor to the word “Edit” and press the
key. The user now has two
pages of configuration for the single payload of their choice.
2. When the payload selection is complete press
to return to the main
measurement screen. Only measurements supported by the selected payload are
available. Invalid measurements have oval symbols beside them.
The table below shows the single payload settings required to enable each of the tests.
