Need Technical Support on -  BNO055 - Difference between silk print A6 and A9

One of our productS has been using one of your components since last year.

Part Number : BNO055

Description: Intelligent 9-axis absolute orientation sensor.

However, we encountered some problems recently when we were using this BNO055 senero.

We were ordering/using as below before, it worked as expected.

Silk print:
701
A9
LRY 

However, the last batch we ordered didn't work as we expectation.After deeper investigation, we found the silk print differs from the ones we ordered before.

Silk print:
701
A6
LRY

We checked the datasheet, we found the 2nd line from your datasheet shows this is for your internal use purpose.

I contact you immediately and want to get your support on below points :

1>. What's the difference between A9 and A6? Are they compatible with each other?

2>.If A6 isn't compatible with A9, what's the best solution for us to correct the problem? (we found the A6 sensor doesn't work)

3>. Or maybe we ordered a wrong sensor or a fake sensor?

Looking forward to support and Thank you very much!

Hi,

The second row marking was internally used.
—— I know this is for your internal use, this is why I'm contacting with you to get the difference between A6 & A9.
If there is NO any special meaning, I assume A6 & A9 should have same function from the datasheet.

So, please confirm the difference between A6 & A9;

If what I ordered are fake chips, Can Bosch support me on analysising the details? Or how should we  punish the sellers?
I believe Bosch should have a immediate punishment mechanism to the sellers.
We should use legal proceedings if necessary. In this case, we need support from Bosch as well.

So please don't keep silent. since this is a big deal for us.
Thanks
