Note 1: Secondary function is selectable in
smart
BASIC application.
Note 2: DIO = Digital Input or Output. I/O voltage level tracks VCC.
Note 3: AIN = Analog Input
Note 4: DIO or AIN functionality is selected using the GpioSetFunc() function in
smart
BASIC.
Note 5: AIN configuration selected using GpioSetFunc() function.
Note 6: I2C, UART, SPI controlled by xxxOPEN() functions in
smart
BASIC.
Note 7: SIO_21 to SIO_24 are DIO by default when $autorun$ app runs on power up.
Note 8: RF_ANT pin (pin30) is on theBL600-ST module only. Customer MUST use 50-Ohm trace from
RF_ANT pin to RSMA RF connector on host PCB. More details on 50-Ohm trace design refer to
section
50-OhmsRF Trace on Host PCB for BL600-ST .
Note 9: Hidden JTAG (2-wire interface), pin22 (SWDIO) and pin23 (SWDCLK). Used for upgrading
smart
BASIC runtime engine FW only with Laird supplied J-link programmer. Using this hidden
JTAG requires 12K resistor to GND (on pin23 SWDCLK) on customers host PCB and header
connector Samtech FTSH-105-01-L-DV, refer to section
Miscellaneous (hidden JTAG)
for details.
Note 10: Pull the nRESET pin low for minimum 100 mS in order for the BL600 to reset.
Note11: SPI CS is created by customer using any spare SIO pin within their
smart
BASIC application script
allowing multi-dropping.
The BL600 module is delivered with the integrated
smart
BASIC runtime engine FW loaded (but no onboard
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
smart
BASIC Application script to be either inputs or outputs with weak or
strong pull-ups or pull-downs. When an alternative SIO function is selected (such as I2C or SPI), the firmware
