Configurations
|
|
==============
|
|
|
|
nsh
|
|
---
|
|
|
|
Basic NuttShell configuration (console enabled in UART0, exposed via USB connection, at 115200 bps).
|
|
|
|
wapi
|
|
----
|
|
|
|
Enables WiFi support
|
|
|
|
mqttc
|
|
-----
|
|
|
|
This configuration tests the MQTT-C publisher example.
|
|
|
|
From the host, start the broker and subscribe to the :code:`test` topic. Using
|
|
`mosquitto` this should be::
|
|
|
|
mosquitto&
|
|
mosquitto_sub -t test
|
|
|
|
From the NSH, connect to an access point::
|
|
|
|
wapi psk wlan0 mypasswd 1
|
|
wapi essid wlan0 myssid 1
|
|
renew wlan0
|
|
|
|
Publish to the broker::
|
|
|
|
nsh> mqttc_pub -h 192.168.1.11
|
|
|
|
The default behavior is to publish the message :code:`test`. The following should be
|
|
outputted::
|
|
|
|
nsh> mqttc_pub -h 192.168.1.11
|
|
Success: Connected to broker!
|
|
Success: Published to broker!
|
|
|
|
Disconnecting from 192.168.1.11
|
|
|
|
From the host the message :code:`test` should be outputted.
