LAIRD -BL600 SERIES MINI DEVELOPMENT KITS
Laird has produced a new series of breakout boards for the BL600 modules. The basic product is a PCB carrier
board (breakout board) with a BL600-SA-07 version module soldered on it to enable rapid prototyping
capabilities and help advance the product design cycle. The three part numbers from this series represent BOM
(bill of material) variants of a basic core design.
The boards, in order from greatest to least additional hardware, are the BA600, BC600, and BB600 and are
shown below for reference:

BB600
BC600

cell holder and Laird FTDI USB-UART bridge

Each of the breakout boards uses the latest BL600 module variant (top level part # BL600-SA-07) which takes
advantage of Nordic’s third generation silicon (nRF51822-QFAA-Hx0 –256k memory/16k RAM QFN). The BL600-
SA-07 module also integrates Laird’s smartBASIC firmware image v1.8.88.0. The BL600 Release Notes –v1.8.88.0
document (available from the Documentation tab of the BL600 product page) identifies additional features and
improvements available with this firmware image. One key benefit of the v1.8.88.0 FW image is that firmware
upgrades can now be completed 100% over the UART interface, regardless of whether the underlying Nordic
soft device has changed.
OVERVIEW
The Laird Bx600 series of BLE breakout boards provides a platform for rapid wireless connectivity prototyping,
providing multiple options for the development of Bluetooth Low Energy (BLE) applications based on Laird’s
BL600 BTv4.0 single mode modules. More information regarding this product series including a detailed BL600
Hardware Integration Guide and smartBASIC Core and BL600 firmware-specific User Guides are available from
the Documentation tab of the Laird BL600 product pages.
The breakout board kit hardware is offered with the Laird BL600-SA-07 (or higher) hardware variant and
smartBASIC runtime engine FW version v1.8.88.0 or greater.
2.1 BA600
The BA600 variant incorporates all hardware options available in the BL600 Breakout Board design, subsequent
sections 2.2. BC600 and 2.3. BB600 will only list differences from this main description:

This section refers to the Bx600 Breakout Board schematic.
Several options exist to power each of the BL600 breakout boards (see section 4. Power Supply Options for
BL600 Breakout Boards) however the BB600 will require added components prior to supplying power to the
board. The easiest solution for the BB600 is listed below and more options can be found in section 4.
Note: At a minimum, the decoupling capacitor, C2 (0.1uF,0402), located near the VCC input pin of the
BL600 module should be fitted on the BB600 to eliminate noise at the supply input.

3.2 UART smartBASIC Firmware Upgrade through Laird FTDI USB-UART Bridge Board
BL600-07 modules with smartBASIC runtime engine firmware version FWv1.8.88.0 or above is required that
allows UART to be used to load and upgrade smartBASIC firmware, as well as the underlying Nordic softdevice –
no JTAG interface is required.
Figure 7: UART smartBASIC FW upgrade
If newer than v1.8.88.0 BL600 smartBASIC firmware is available from the Software Downloads section of the
Laird BL600 Series webpage; you can then upgrade the firmware through the Laird FTDI USB-UART bridge board
by completing the following steps:
1. Check the BL600-07 modules with smartBASIC runtime engine FW version by typing at i 3.
Figure 8: Type at i 3.
2. Close UwTerminal, but do not disconnect the BA600-0x.
3. With BA600-0x still connected to a PC through the Laird FTDI USB-UART Bridge Board interface, double
click on to Laird utility BL6xxUartFwUpgrade.exe
4. Select the COM port, confirm the firmware version to be uploaded and click OK.

3.3 AutoRUN Function
The nAUTORUN signal (SIO_28 of BL600; pin 40) is brought out onto J5 pin 2. See the schematic in Figure 12.
Figure 12: J5 schematic
The nAutoRUN pin needs to be externally held high or low to select between the two BL600 operating modes:
Self-contained Run mode (nAutoRUN pin held at 0V). Insert jumper between J5 Pin 2 and Pin 1.
Interactive/Development mode (nAutoRUN pin held at VCC). Insert jumper between J5 Pin 2 and Pin 3.
The smartBASIC runtime engine firmware checks for the status of nAutoRUN during power-up or reset. If it is
low and if there is a smartBASIC application named $autorun$, then the smartBASIC runtime engine executes
the application automatically; hence the name self-contained run mode.

nAutoRUN
(SIO_28)
Pin 40 of
BL600
Input with active low logic
Operating mode selected by nAutoRUN pin status:
If LOW (0V), runs $autorun$ if it exist. (Insert jumper between J5 Pin 2 and Pin 1)
If HIGH (VCC), runs at+run and file name application (Insert jumper between J5 Pin 2 and Pin 3)
To initiate autoRUN, follow these steps:
1. Start by loading a smartBASIC application that can run from autoRUN at power up (Figure 13).
Figure 13: Load smartBASIC application
2. In UwTerminal, do a compile and download and select $autorun$.iBeacon.sb (for example).
Figure 14: Compile and download
3. Verify that the application exists as $autorun$ by issuing at+dir.
4. Unplug the Laird FTDI USB-UART bridge board.
5. Install a jumper between pins 1 and 2 of J5 (nAutoRUN set to Low to put module into autorun mode).
6. Install a coin cell battery (CR1632)(Figure 15) in the slot on the bottom of the module.

7. Using the Laird ToolKit Proximity app (for example, just to pick up the advert) on Android, search for the
beacon. If successful, the BL600 beacon displays as shown in Figure 16.

3.4 VSP Command Mode
This section discusses VSP Command mode through pulling SIO_7 high and nAutoRUN low. Read this section in
conjunction with the VSP Configuration chapter of the following guide:
User Guide - smartBASIC BL600 Extensions Release 1.5.70.0.pdf
Figure 17 shows the difference between VSP Bridge to UART mode and VSP OTA mode and how SIO_7 and
nAutoRUN need to be configured to select between these two modes.
VSP Bridge to UART mode takes data sent from phone or tablet (over BLE) and sends to BL600 to be sent
out of the BL600 UART (therefore data not stored on BL600).
VSP Command mode takes data sent from phone of tablet and sends to BL600 and stores that data in the
BL600. The OTA Android or iOS application can be used to download any smartBASIC application script over
the air to the BL600.

Insert jumper between J5 pin5 and 6.
High
Insert jumper between J5 pin2 and 3.
VSP Command Mode
High
Insert jumper between J5 pin5 and 6.
Low
Insert jumper between J5 pin2 and 1.
SIO_7 High (externally) selects the VSP service and together when nAutoRUN is Low (externally), selects VSP
Command mode whilst nAutoRUN High (externally) selects VSP Bridge to UART mode.
When SIO_7 on module is set HIGH (externally), VSP is enabled and auto-bridged to UART when connected.
However, for VSP Command mode, auto-bridge to UART is not required. With SIO_7 set to High and nAutoRUN
set to Low, VSP Command mode is entered and you can then download the smartBASIC application onto the
module over the air from the phone (or tablet).
SIO_7 V (BL600 pin9) is brought out onto J5 pin 5. See the following schematic (Figure 18).
