Indicator and switch description

Button:

• Mode button（MODE）: Keep pressing this button, the BTBee Pro module will

enter AT command mode; Release this button, the BTBee Pro module will return data mode.

• Reset button (RESET): Press the button to reset the BTBee Pro module

Switch:

• Data or Program Switch: When this switch be set to “COM” site, the BTBee

Pro module is in data mode, and can be used for Bluetooth communication. When the switch be set to “Upload” site, the BTBee Pro module is in program mode, and can be used to upload program to Arduino.

LED:

• Status light: Without any data transmission, the flicker frequency of the

light if 106ms;during the data transmission, the light blinks twice in 106ms frequency, and stops for two seconds, then goes on blinking as before until the transmission is complete.

• Linking status light (Con): The LED will be on if the BTBee Pro module not

connect with any device; The LED will be off when the BTBee Pro module connect to some device.

• Power light (PWR): The light is on when power on.
