Detailed Description

Morse Micro Embedded Test Engine (Emmet) example.

Note

It is assumed that you have followed the steps in the Getting Started guide and are therefore familiar with how to build, flash, and monitor an application using the MM-IoT-SDK framework.

Morse Micro Embedded Test Engine (Emmet) is a firmware subsystem that allows various aspects of the firmware to be driven by a connected computer via a connected OpenOCD server. This is intended as an aid for development and automated test.

This example application simply initializes the Emmet subsystem, making it ready to receive commands.

How to use the Emmet example application

The following instructions demonstrate how to connect to an AP and perform a ping.

Begin by following the instructions in the Getting Started guide to build the emmet.elf firmware and use OpenOCD/GDB to program it to the microcontroller (see also Application helper routines for Wireless LAN interface for more details of WLAN and IP stack configuration). Once programming is complete leave OpenOCD running. If this is not the case OpenOCD can be started with the following command (the exact command will vary between platforms, see Launching OpenOCD):

openocd -f src/platforms/mm-ekh08-u575/openocd.cfg

In another terminal execute the wlan-sta-connect.py script to connect to the AP:

pipenv run ./tools/ace/examples/wlan-sta-connect.py -H localhost -s MorseMicro -S SAE -p 12345678

This will connect to the AP with SSID MorseMicro, using SAE encryption and passphrase 12345678.

Note

Every example script has a help flag for more information about the script parameters. For example:

pipenv run ./tools/ace/examples/wlan-sta-connect.py -h

The script will return once connection is complete. In addition the following message similar to the following will be observed in the firmware log:

Link is up. Time: 48364 ms, IP: 192.168.1.2, Netmask: 255.255.255.0, Gateway: 192.168.1.1

To ping a device on the network use the ping.py script. For example:

pipenv run ./tools/ace/examples/ping.py -H localhost -I 192.168.1.1 -c 10

This will ping 192.168.1.1, sending 10 ping requests at an interval of 1000 ms.

A number of other scripts for exercising various aspects of the firmware can be found in the tools/ace/examples directory.

Function Documentation

app_init()

void app_init

(

void

)

Main entry point to the application.

This will be invoked in a thread once operating system and hardware initialization has completed. It may return, but it does not have to.
