Tip:
If the module returns a four hex digit error code: In UwTerminal, select those four digits, right-click,
and select Lookup Selected ErrorCode (select Lookup Selected Error-Code (Hex) if using
UwTerminalX). A description of the error is then printed on screen.
The following are the differences between UwTerminal and UwTerminalX:
UwTerminal is Windows only whilst UwTerminalX is cross platform
UwTerminal and UwTerminalX have the same overall functionality but some UwTerminal functions are not
available in UwTerminalX including File Player, BASIC tab, multiple file downloading at once, and
communication over TCP port.

J40, J44, J29, J41, J1, J5 SIO (Special Input/Output Sockets) Breakout Connectors
Access to all 32 BL652 series module signal pins (SIO’s = Signal Input /Output) is available on header connectors
J40, J44, J29, J41, J1, J5 (2.54 mm pitch headers).
Note:
The BL652 module signal pins designation SIO (Signal Input /Output).
DEFAULT type is DIO (Digital Input or Output) or UART (on fixed pins)
ALTERNATE type is either AIN (Analog Input ADC), I2C, SPI, DIO (on fixed pins), PWM, FREQ, and NFC
DIO or AIN functionality is selected using the GpioSetFunc() function in smartBASIC
I2C, UART, SPI controlled by xxxOPEN() functions in smartBASIC
SIO_5 to SIO_8 are DIO by default when $autorun$ app runs on power up
SIO_9 and SIO_10 are NFC pins by default, can be set to alternative function SIO using the GpioSetFunc()
function in smartBASIC
These breakout connectors can interface to a wide array of sensors, the BL652 is user configurable through the
smartBASIC application script to change each SIO pin from the default function (DIO, UART) to alternate
functions (AIN (ADC), I2C, SPI, DIO), PWM, FREQ, and NFC. The BL652 development kit incorporates additional
fly-lead cables inside the box to enable simple, hassle-free testing of these multiple interfaces.
Table 7
shows the BL652 module pins that are brought out to plated through Holes (suitable for 2.54 mm pitch
headers).
