BreathUp, Bluetooth interfacing and Post Request

Good Evening!

During this end of the week, I spent my time to interface the Bluetooth Application with the code which made by Alexandre in order to connect the smartphone to the Bluetooth unit and do long exchanges. After some problems and tests, the two devices are interfacing.

Since yesterday, Xavier has changed the encryption’s algorithm and the server request. I have began to switch the two Get requests to Put requests, but I will finish that next week.

Before the interfacing of the Bluetooth, I spent few times on the IMU driver to understand how the I2C communication works .

Have a nice week,


BreathUp, Bluetooth exchanges

Hi everybody,

Monday with Alexandre, we worked together to test our works and know if the app could exchange data with the Bluetooth module. That was conclusive. After that, the steps was the thought about the communication between the device and the server. There were debates with Alexandre and Xavier about that and its security. Thanks to that, we have established a “protocol” between the different elements. Therefore, I  have begun its implementation for the app. Therefore, I will continue to work on during the end of the week.

Simultaneously, I also worked on sending http requests to the server and giving back the answer. To do that, Xavier explained me how generate valid encrypt messages with a python script. I also continued to develop the Bluetooth server to be able to do tests and work alone. I took some times in order to clean the code, remove bugs and add commentaries.

This week, PaulGWF organized “Rose Events”. He put forward us to do a secret Santa and a dinner together. Those were good moments together and cool. So, thank you PaulGWF and others.

BreathUp, week 11

Hi everyone,

During this last days, I finished implimenting the Bluetooth server to test an connexion between two devices and it has worked. Indeed, the application can send and receive data.

As I said in the last post, I worked to make a http request. The application can do a GET and receive the answer.

Therefore, the next step, it is to interface the application and hardware Bluetooth unit with Alexandre. I have begun to think about that. But I will have to talk with Alexandre to choose the best solution.

That’s all.
