Software example using EV-COG-SMARTMESH1Z
This document explains how temperature data can be sent via EV-COG-SMARTMESH1Z configured in the slave mode to the E-manager connected to the users PC. It also explains the software flow and how to view the expected output.
Software Details
A modular software framework is provided for quick application prototyping. Based on the application use case, developers need to download the respective software packs.
The EV-COG-SMARTMESH1Z interfaced EV-COG-AD3029LZ , software development kit consists of these packs:-
- BSP - Board Support Package for EV-COG-AD3029LZ - This pack along with the DFP is required to develop applications using the on-board drivers.
- SmartMesh C library- This pack is required for the implementation of the serial APIs of the EV-COG-SMARTMESH1Z and nullifies the need for application software to deal low level processes.
For details on the C-Library, follow thislink
Software Overview
- Application software has provisions to handle sensor data collection or preprocessing of collected data and can draw implications on the collected data.
- BSP handles sending and receiving of packets over UART interface.
- C-LIB is a library for handling API calls, HDLC packetisation, etc.
Software Architecture
This section gives user a basic understanding on how the software is designed for handling both transmission and reception of packets between the EV-COG-SMARTMESH1Z and EV-COG-AD3029LZ.

Transmission of Packets
The Application level software handles tasks such as invoking API commands, handling API replies and performing user-application specific tasks. The C-Lib later performs HDLC packetization and other tasks there by making it easy for the user to send commands to the EV-COG-SMARTMESH1Z. In the BSP, APIs specific to UART communication aid in sending transmit packets over the UART lines.
Reception of Packets
When EV-COG-SMARTMESH1Z sends a packet to EV-COG-AD3029LZ, the received packet is written to a circular buffer using the UART specific APIs of the BSP. At the application level software , the circular buffer is continuously checked for data written. When a byte of data is written to the circular buffer, the application level software calls routines that handle the data written to the buffer. The C-Lib processes the received packet and sends a callback to the application level software with only the required field in the received packet.

Interface Guide
This section covers the various steps involved in the interface of the EV-COG-SMARTMESH1Z with EV-COG-AD3029LZ and thereby run the C-library on the EV-COG-AD3029LZ and get it to talk to EV-COG-SMARTMESH1Z.
Following are the steps involved :-
- Connect the EV-COG-SMARTMESH1Z with EV-COG-AD3029LZ as shown in the Board Interface section.
- Download and Install the necessary soft wares for working with the EV-COG-SMARTMESH1Z and EV-COG-AD3029LZ as mentioned in the Software Details section.
- For setting up the SmartMesh-IP-Manager follow this link.
- Download the Source code.
- Place the contents of the SmartMesh C-Library in the your project folder.
- Here is a list of files of the SmartMesh C-Library you need to include in the project folder:-
- dn_endianness.c
- dn_hdlc.c
- dn_ipmt.c
- dn_lock.c
- dn_serial_mt.c
- Import the source into IAR and run the application software.
Importing source file to IAR
Here is the link for working with IAR Embedded Workbench for programming EV-COG-3029LZ which cover topics related to initial settings and project importing tasks and running the projects.
Successful Interface of EV-COG-SMARTMESH1Z with EV-COG-AD3029LZ
Steps to obtain output as shown in fig.1 :-
- Open Tera Term.
- Click on Serial and select the Com port to which the manager is connected.
- Type “login user” .
- Type “sm” which is a command for showing all the motes connected to the manager.
Steps to obtain output as shown in fig.2 :-
- Click on APIExplorer.exe.
- Select Manager and click on connect through “serialMux” or through specific Com port.
- In the command window select “subscribe”.
- To subscribe to all notifications fill “FFFFFFFF” in the filter section and “00000000” in the unackFilter.
- In the “ notifications “ section, one can see the data and other notifications.
Steps to obtain output as shown in fig.3 :-
- Click on TempMonitor.exe.
- Press “load” manager.
- In the mote list, the temperature data sent by the mote is visible.
Example project
To download an example project to interface EV-COG-SMARTMESH1Z with EV-COG-AD3029LZ click on "SmartMesh-Temperature-Sensor-Software"
The example project sends temperature data or a dummy data to the manager which can be viewed on TempMonitor(GUI) or on the APIExplorer(GUI) of the manager.
