ZBA, Inc. Please contact ZBA for details on purchasing a development board to interface the module to the PC. Microcontroller Interface: The UART of the Bluetooth module can directly connect to the microprocessors UART. The Microprocessor must have an I/O that will operate from 0 to 3.3 Volts or the appropriate level shifter circuitry must be used as to not overstress the I/O of either device. Please note. The modules will only response the host set-up commands after the module has entered the command mode. For module to enter in the command mode, the host must send a single character ESC <0x1b> within 5 second after the unit has been powered on. If the ESC character is not sent within the specified 5 second window then the module will automatically enter the SPP mode and any information sent to the UART will be treated as data to be transmitted over a Bluetooth link. Note: All Commands except the first <ESC> command contain a suffix of <CR><LF>. 8.2.1 Entering the Set-up Mode Command Response Parameter ESC <CR> OPEN:num<CR><LF> Num= 0: device is not paired Num= 1 Device is currently paired 8.2.2 Testing the Communication Link Command Response Parameter AT OK None 8.2.3 Command list Command Response Parameter ATZ?

Note2: While in Master Mode the module will respond with +INQRES: remote BTADDR for each of the Bluetooth devices that are in the neighbourhood To connect to a particular device you will need to type AT+RADDR= BT address (the specific device you wish to pair determined from the AT+INQ? Command).

OK +BIND<Para1> Para1 0 =Always paired 1 = Drop pair Default=1 Drop pairing Note: The default mode is to drop pair. The drop pair function occurs when the module is power-off then back on or the master drops pairing. This will allow another master to commence a discovery process and connect to the module (slave) device. If the device is set-up as always paired then the module will only communicate with the specific master whose address it has been bonded to even after power off and power-on. This mode is useful for application where a cable replacement function is the required. To communicate to a different master the module must have the bonded address cleared. This is accomplished by running the AT+CLEARADDR command. 8.2.17 Inquire Version Command Response Parameter AT+VERSION OK +VERSION<Para1> Para1 version # Note: This command will return the firmware version of the module. . 8.2.18 Inquired remote device Address Command Response Parameter AT+INQ?

OK RADDR<Para1> Para1 Paired device address Example to set-up the Module to communicate with one specific BT device whose BT address is currently unknown. First type: AT+INQ? What is returned are the BT addresses of the devices in the BT neighbourhood. Then type AT+RADDR= BT address (the specific device you wish to pair determined from the AT+INQ? Command). The module will remain bound to this address until the AT+CLEARADDR is run or the module is powered off and then back on again. 8.2.20 Inquired Device BD Address Note: This command returns the (local) BT address of the module. 8.2.21 Software Reset Command Response Parameter AT+ RESTART OK None 8.2.22 Set/Inquire about Low power mode Command Response Parameter AT+LOWPOWER=<Para1> OK <Para1>： 0： low power disabled 1：Low power mode Enabled AT+ LOWPOWER?

OK ＋FLOWCONTROL：<Para1> 8.2.25 Exiting the Set-up Mode Command Response Parameter AT+EXIT None None Note: This command returns the module to SPP mode. 9 Low power modes 9.1 Park & Sniff The module will automatically go into a reduced power mode if there is no UART activity and no RF activity. The Device will sniff in order to maintain synchronization with the Master. To save maximum power then it is possible to completely turn-off the power to the module. When operating in this mode the Master/ Slave must then proceed through the Discovery phase (consuming time and energy) before a connection can be re-established. This mode is

ZBA, Inc. only recommended if there are very, very long periods of inactivity and the battery power is of the utmost concern.

ZBA, Inc. 10 Mounting recommendations For maximized performance please orient the device with the antenna as close to the outside of the housing as possible. Best performance will occur if the underlying PCB does not have a ground plane under the area where the antenna is located. The nearest ground plane should be at least 3mm away from any point on the antenna.
