Then, besides the specific serial connector used (case
), run an AT terminal
application (as for example, the u-blox m-center tool) by selecting the appropriate AT COM port
with these settings:
o
Data rate: 57'600 bit/s
o
Data bits: 8
o
Parity: N
o
Stop bits: 1
o
Flow control: disabled
9.
It is possible to access SARA-N3
module’s
additional UART FT for diagnostic purpose. To do so:
Connect a USB cable to the mini USB connector (
Cellular USB
, J501 on EVB). LED DL501 lights
blue.
In this case, two COM ports are enabled with Windows (the numbering of the COM ports can be
seen via the Windows Device Manager):
o
SARA-N3 series UART interface is available over the first COM port (for AT commands and
data)
o
SARA-N3 series additional UART FT interface is available over the second COM port (for FW
update and diagnostic)
Make sure to appropriately set the related slide switches:
o
SW401 set to ON-BOARD
o
SW403 set to MINIUSB
o
SW510 set to UART1
Then, run a terminal application (as for example the u-blox m-center tool), selecting the
appropriate diagnostic COM port with the following settings:
o
Data rate: 921'600 bit/s
o
Data bits: 8
o
Parity: N
o
Stop bits: 1
o
