Sprint 2

[Sankalppund]

1. Installation of Python and it's supporting modules in the buildroot.

• [x] DoD: Able to run python script successfully with all associated python modules.

Commit Link: Python Testing

2. Client-side MQTT application development.

• [x] DoD: Messages (sensor data) are sent from the client-side and received successfully on the MQTT server-side.

Commit Link: MQTT Server/Client Working

3. Configuring NTPD package in buildroot for logging purpose.

• [x] DoD: System time updated and confirmed by getting timestamps in Syslog on bootup.

Commit Link: NTPD

4. MAX30102 Heart rate sensor datasheet study for application development and Testing of the sensor.

• [x] DoD: Able to configure the heart rate mode in MAX30102

Commit Link: Application Testing

(Follow-on task of issue-4 for sprint 3: Tried developing the C application for heart rate sensor as per the data sheet but readings are not as expected and also tried implementing python application but not getting the accurate sensor data. Issue 4 will be further developed in sprint-3)

1. Blocker Identified: Dependancy on the MQTT server to check if messages from MQTT clients are received.

2. Blocker-2: In order to build and check the python3 supporting packages, There is trouble while login after clean.sh and build.sh as shown below in the image.

[Sankalppund]

3. Blocker-3 : Python3 supporting packages are not getting installed, for example 'numpy' (as shown below in attached image) through buildroot and thus python script cannot be run in raspberry pi in order to take data from heart rate monitor sensor.

4. Blocker-2 was removed and the associated problem has been resolved using the following steps and now I am able to login.

5. Blocker-3 was removed and the associated issue has been resolved.

• Earlier python 2.7 was having an issue of missing "hashlib" module which got resolved with the installation of python3 support but python3 was having issue of missing 'numpy' and 'smbus' modules.

• Now with both python2.7 and python3 installed solved the above problems.

Issue-2: "Client-side MQTT application development" has been implemented and closed and tested successfully as below.

MQTT Server application waiting for the MQTT client connection:

MQTT Server accepts the message delivered from the MQTT Client side after accepting the connection.

[Sankalppund]

Identified Blocker-1 was removed by developing and testing both MQTT Server and Client application on the same localhost

Issue-3 "Configuring NTPD package in buildroot for logging purpose" has been done and closed. System time has been configured and tested on bootup sequence as shown below:
