BQ26220 Battery Manager RS232 Communication Lost

Hello,

I actually use a BQ26220 to know the capacity of a non rechargeable battery.

My problem is that the software use to evaluate the BQ26220 don't understand the answer of the BQ26220. I have a communication (See the attachment) between the host and the BQ26220. So I think that the BQ26220 understand the command and answer.

But in the soft i have no data and it is written "RS232 Communication Lost" even if the host send and receive something.

So if someone can help me.

I use an EV2200 to communicate between the BQ26220 Battery manager and the BQ26220.

Thanks you in advance for your Answer

Best regards,
