BL600-Sx Hardware Integration Guide
Single Mode BLE Module
The BL600 module is delivered with the integrated
smart
BASIC application script). Because of this, it starts up in AT command mode by default.
At reset, all SIO lines are configured as the defaults shown above.
SIO lines can be configured through the
pull-ups or pull-downs. When an alternative SIO function is selected (such as I2C or SPI), the firmware does not
allow the setup of internal pull-up/pull-down. Therefore, when I2C interface is selected, pull-up resistors on
I2C SDA and I2C SCL MUST be connected externally as per I2C standard.
UART_RX, UART_TX, UART_CTS are 3.3 V level logic (if VCC is 3.3 V, i.e. SIO pin I/O levels track VCC). For
example, when RX and TX are idle, they sit at 3.3 V (if VCC is 3.3 V). Conversely, handshaking pins CTS and
RTS at 0 V are treated as assertions.
Pin 40 (nAutoRUN) is an input, with active low logic. In the development kit (DVK-BL600-sx) it is connected so
that the state is driven by the host's DTR output line. The nAutoRUN pin must be externally held high or low to
select between the following two BL600 operating modes:
Self-contained Run mode (nAutoRUN pin held at 0 V).
Interactive / development mode (nAutoRUN pin held at VCC).
smart
BASIC runtime engine firmware checks for the status of nAutoRUN during power-up or reset. If it is low
smart
and if there is a
BASIC application script named $autorun$, then the
executes the application script automatically; hence the name S
3.3 Electrical Specifications
3.3.1 Absolute Maximum ratings
Absolute maximum ratings for supply voltage and voltages on digital and analogue pins of the module are
listed below; exceeding these values causes permanent damage.
