No data from sensors

[BanjoFox]

I am running into an issue where the sensors do not appear to be collecting any data.
the EEG is "--"
the O2 is"--"
the temperature is "--"

this is from the Windows GUI, and the Pi touchscreen.

Hi,

When did it stopped working? after programming or something else ?
Is the led on spo2 probe is glowing ?
Are you getting any data on serial terminal ? try connecting to any serial terminal instead of connecting with gui. [baud rate = 115200 on windows]

if you tried to upload, which is the board selected on arduino? other upload configurations used on arduino ?
A photo of your set up will also be very helpful.

Hello,

It stopped reporting data after flashing the Firmware Update. Even from the factory, I was having some troubles with it.
There is a red LED on the HAT itself.
I was not aware that there was a serial terminal. Is that the same DB plug that the PulseOx connects to?
On the Arduino Studio the device selected is the Arduino Zero (Native). I can get the full screenshot later. When I do the uploads they appear to complete. I do not recall if there are any warnings, but certainly there are no errors.

As I was digging around in the CLOSED issues I found a thread that was very similar to the issue I was having (except I am using Stock Firmware).

You have to DOWNGRADE the Arduino Board version that Arduino Studio wants you to use.
Here are the steps to do that

• Load Arduino Studio
• Click Tools > Board > Board Manager

Search "SAMD" and look for the one that says Arduino SAMD Boards (32-bits ARM Cortex-M0+)
Under the "Boards included in this package" there will be one that will say "Arduino Zero"

Click "Select Version" and scroll down until it says 1.6.15. and click the Install button.
If your Healthy Pi is plugged in, unplug it, and plug it back in to reset the board.

Now go to Tools > Board > Arduino SAMD Boards (32-bits ARM Cortex-M0+), and select the one that says "Arduino/Genuino Zero (Native USB Port)

Now open the Firmware Update from https://github.com/Protocentral/protocentral-healthypi-v3/releases/tag/v1.1, and it should fix the issue :)

Just a quick note that the Arduino Studio will want you to UPDATE every time you load the program. DON'T :D

I have the same issue, brand new out of the box yesterday. Stock firmware. Wasn't planning on learning the Arduino IDE.

Healthy Pi isn't cheap, anyone else have a solution not involving using refreshing Arduino?

Thanks

Steve

@Steveoyoung Do you have the HealthyPi 3 or HealthyPi 4? Can you also please post a screenshot if possible?

[Steveoyoung]

Ashwin, Thanks for you quick reply, Healthy Pi 4, connect3ed to a PI3. Removed the serial stuff from cmdline.txt and added the overlay to the config.txt Pulled out of the box yesterday … any ideas?

Thank you sir, you just solved my problem. Sir can you please tell me how to get the streams on gui window because i'm not able to find the port assign for healthy pi inside there. How can i get the readable form of sensors data?
