10. For communication via the TOBY- L2 module’s UART interface, the following connections are
allowed and can be alternatively enabled in a mutually exclusive way (see Table 6 for switch
position and LED status):
o
Connect a USB cable to mini USB connector ( Cellular USB , J501 on EVB), LED DL501 lights
blue
o
Connect an RS232 cable to DB9 connector ( Cellular RS232 , J500 on EVB)
When a USB cable is connected to the mini USB connector, two COM ports are enabled in
Windows (the numbering of the COM ports can be seen via the Windows Device Manager). The
serial port for AT commands is available over the first numbered COM port opened by the driver.
Type of connections SW401 SW403 LED
Access to cellular UART over the Cellular USB (UART) mini USB connector
(J501)
ON BOARD MINIUSB DL403
Access to cellular UART over the Cellular RS232 (UART) DB9 connector (J500) ON BOARD DB9 DL405
Access to cellular UART on DIL Board-to-Board connector on the adapter board:
cellular UART detached from USB (UART) J501 and RS232 (UART) J500
connectors B2B Do not care DL404
Table 6: Serial interface configuration
Run an AT terminal application (e.g. the u-blox m-center tool) selecting the COM port, with these
settings:
o
Data rate: 115200 b/s
o
Data bits: 8
o
Parity: N
o
Stop bits: 1
o
Flow control: HW
See Appendix A for how to configure the u-blox m-center AT terminal for Windows.
11. If the audio functionality is required, connect the headset provided with the evaluation kit box to
the
Headset jack connector (J303 on EVB).
1.9 Enabling error result codes
Command sent by DTE (user) DCE response (module) Description
AT+CMEE=2 OK
Enables the cellular module to report verbose error
result codes.
1.10 PIN code insertion (when required)
Command sent by DTE (user) DCE response (module) Description
AT+CPIN="8180" OK Enter the PIN code, if needed (enter the PIN of the SIM
card
– 8180 is written here as an example).
AT+CLCK="SC",0,"8180" OK Unlock the PIN at power on (the last parameter is the
PIN of the SIM card
– 8180 is written here as an
example).
AT+CLCK="SC",1,"8180" OK Lock the PIN at power on (the last parameter is the PIN
of the SIM card
– 8180 is written here as an example).
