Running a Script in Null Packets Mode
This mode is used to enable indicative measurements to be made on EUTs that have no
test mode support. In this mode the MT8850A/MT8852A does not use Test Mode
signalling at all, and makes only a limited subset of measurements on packets without
payloads. Measurements are not performed in accordance with the Bluetooth test
specification. When the user selects to run a script in null packets 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.
The MT8850A/MT8852A can be made to link to an EUT and maintain the link by sending
POLL packets. In response to a POLL packet, the EUT will return a NULL packet. A NULL
Packet has no payload but can be used for power, initial frequency, drift, and modulation
measurements without having to activate test mode.
