Number of Data Bits	8
Number of Stop Bits	1

6.4MTK RF Protocol

Command packets received by the Device-Under-Test (DUT) are ‘echoed’ with the addition of an added byte that contains the count of invalid bits for the received packet. Extra bytes in packets that are larger than what the DUT can support are ignored. Commands other than ‘Echo Packet’ are only ‘echoed’ and executed if the number of invalid bits are zero.

The RF command packets exchanged between the MTK Tester and the MTK DUT contain two bytes. The first byte contains the command type and the subsequent bytes contain the parameter values as shown in Table 6-4.

Table 6-4. RF Commands

Description	Command	Parameter
Echo Packet	0x00	N/A
Set New Configuration	0x61	Channel (0-77)
		PN code index (0-7)
		PA (0-7)
		Correlator Threshold (0-16)
Transmit carrier	0x66	Time in seconds (0-255)
		Note A zero runs the test continuously until a reset.
Transmit random pattern	0xA3	Time in seconds (0-255)
		Note A zero runs the test continuously until a reset.

The ‘Transmit carrier’ and ‘Transmit random pattern’ test mode can be conditionally compiled with the define MFG_TX_MODES.

6.5MTK DUT Source Code Porting

The RDK keyboard, bridge and mouse use the C source files mfgtest.c and mfgtest.h. Select the appropriate source files for the target platform as a starting point. Make code changes as necessary to work in your environment.

6.6Accessing MTK in the DUT

Mouse: Apply a jumper across the ISSP header pins 4 and 5, and install the batteries.

Keyboard: Same as mouse.

Bridge: Press the Bind button while plugging it into the USB port. The LED’s should blink.
