Read Uart based sensor data on nrf5340 using VsCode?

[Stephanie]

Hi,

I'am using the  Ultrasonic Oxygen Senor with the nrf5340, the output is like this "photo" I want to calculate the concentration and the purity and with this values I had wrong results, so can you help to solve this problem?

 I am using this code

4857.gasboard.zip

 and here is my result.

this technical specification for my sensor.

Could you please help me to solve this problem

Hello!

Did you write the code you're using yourself?

Can you please explain what you expect your code to do and how the results differ from your expectations?

Best regards,

Einar

Hello!
Thank you for your response
The code found in devzone for nrf9160
The first step, I want to read the data through the UART connection.
The second step, I have to read the flow rate and purity of oxygen.

There is many illogical values, "many zeros" that gives wrong results
Meilleures salutations,

Can you please be more specific?

Have you made sure your program follows the communication protocol in the technical specification you linked?
