Hi,

my customer forms daisy chain with 16 BQ79616, and they are concerned if the worker accidentally connect COMH of device 1 to COMH of device 2, will the communication still work?

Any method to directly find the wrongly connected device?

Is it possible to configure through software to let the wrongly connected device communicate as normal? How?

Thanks.

Hi Howard,

No this is not correct intention of the device to work. You could have accidental collision of the communications this way. I suggest to have diligent checks before reconnecting the modules.

Taylor,

thank you. So we can only check the connection by inspecting the modules one by one. It's not possible that we can tell from software or any registers?

Howard,

Well the module connected incorrectly would likely not communicate anything back so you would find out that way via software.
