There seems to be an error with the Ble stack.

Hello,

I am working on SDK v14 version mpu6050 sensor. I found an example of mpu6050 here.

https://github.com/Martinsbl/nrf5-mpu-examples

And here I found a way to change this example source to a segger file.

https://devzone.nordicsemi.com/f/nordic-q-a/39513/mpu6050-with-nrf52832-in-segger/204245#204245

And when I debug, the error is output from the bl_stack_init as shown below.

I've never seen an error like this, can I know this problem?

Thank you.

Hi,

That's a standard adjustment that your application might need, for example when adding more peripherals.

You application just needs more RAM to be allocated to it.

Here is how to fix it, if you're using SEGGER Embedded Studio as an IDE.

Thank you!
Error problem resolved.

The sensor's value is only zero, but this is probably a twi address or pin problem.

Hello, rmptxf.

I've run into the same problem again.
To solve this problem, do I need to make RAM_START and RAM_SIZE larger in the settings as shown above?

[schosdas]

No, it works well because I changed it to a different module. Maybe the previous one was broken because I connected the pin incorrectly.

Thank you!

Happy to help!

Just for the RAM size adjustment, the application will tell you when it's necessary to do so. And even provide you the correct values.
