README for NuttX port to the u-blox C027 dev board.
|
|
|
|
The board is intended for prototyping software for u-blox cellular modems (SARA
|
|
or LISA families) and the u-blox GPS receiver (MAX-7Q, MAX-M8Q, or other,
|
|
depending on board revision).
|
|
|
|
This board features the LPC1768 MCU and is related to the Embedded Artists' base
|
|
board with the NXP the LPCXpresso daughter board, see
|
|
boards/lpcxpresso-lpc1768/README.txt.
|
|
|
|
The board also features an embedded USB debugger.

Configurations
|
|
^^^^^^^^^^^^^^
|
|
|
|
nsh
|
|
---
|
|
|
|
The nsh configuration allows to test the modem and the GPS receiver. The modem
|
|
can be tested in either the internal TCP/IP stack mode or with the NuttX TCP/IP
|
|
stack and pppd.
|
|
|
|
Modem starts in power-down mode and has to be switched on, e.g., using the nsh
|
|
command:
|
|
|
|
nsh> ubloxmodem on
|
|
|
|
To connect using the NuttX TCP/IP stack, use pppd. At the time of writing the
|
|
pppd app is located in apps/examples/pppd and requires setting correct login
|
|
details in the source code.
|
|
|
|
To connect using the internal u-blox TCP/IP stack, use the chat app. Its
|
|
configuration is done in
|
|
boards/arm/lpc17xx_40xx/u-blox-c027/nsh/defconfig and can be adjusted
|
|
using 'make menuconfig'.
|
|
|
|
The NuttX u-blox modem driver is included like this:
|
|
|
|
CONFIG_MODEM=y
|
|
CONFIG_MODEM_U_BLOX=y
|
|
|
|
The nsh app that allows power control is included with the default configuration
|
|
as follows:
|
|
|
|
CONFIG_EXAMPLES_UBLOXMODEM=y
|
|
CONFIG_EXAMPLES_UBLOXMODEM_TTY_DEVNODE="/dev/ttyS1"
|
|
CONFIG_EXAMPLES_UBLOXMODEM_DEVNODE="/dev/ubxmdm"
|
|
|
|
The modem driver uses two device nodes. The TTY device is the modem terminal,
|
|
while the other device is used for general control via GPIO such as power
|
|
control. At the moment only one modem is supported, and the corresponding device
|
|
control node is /dev/ubxmdm.
|
|
|
|
The chat app allows to run scripts. A few such scripts are preset in the
|
|
defconfig:
|
|
|
|
CONFIG_EXAMPLES_CHAT_PRESET[0..3]:
|
|
0 - set up the provider context with username and password,
|
|
1 - connect to the provider,
|
|
2 - open a TCP socket to the u-blox test server,
|
|
3 - test the TCP socket server operation and close the socket.
