FIGURE 1-4: SERIAL PORT SETTINGS IN TERATERM
To place the module on the RN-52-EK evaluation board into command mode, connect a jumper
to header pins 3 and 5 (GPIO9) on J3. See Figure 1-5. When entering command mode the mod-
ule sends CMD to the UART.
FIGURE 1-5: GPIO9 LOCATION
Type the following commands into the Tera Term console:
+ // Turn on local echo
v // Display the firmware version

To switch into data mode, remove the jumper from header pins 3 and 5 (GPIO9) on J3. When
leaving command mode the module sends END to the UART.
