Stat pin
The STAT pin indicates the status of the device. It can be used to drive a LED using a series
resistor. STAT pin drive capability is 10mA (loads the VCC_IO).
The STAT pin has the following behavior.
Blink cycle
Mode
“1”
- statically
module is operational “searching for a new frame”
“0” for the endurance of the
received frame.
“0” when module is receiving data from air interface.
In practical cases will toggle at the frequency of the data
packets on the air interface.
“0” statically
Module is in sleep1 mode
The pin is toggled in transmission
interval
Module is sending data Over the Air
Pin is toggled in 1s interval
Module has the connection to Configuration Manager
program.
Pin is toggled in 500ms interval
SL Command mode.
Pin is toggled in 250ms interval
Module has detected a fault, fault codes can be read via
Configuration Manager program.
Table. Modes of STAT pin.

Service pin
The SERVICE pin is used to set the UART1 into a known state. Pulling this pin low will set the
UART1 into 38400, n, 8, 1. This is intended for service access of the module, to have a known
serial port setting in order to access the module settings.
The pin does not affect any permanent settings, nor does it change the mode of the module.
Releasing/ driving the pin high will return serial port 1 into the configured state.
When service pin is pulled low, the SL Commands are forced to be ON although they are OFF in
settings.
