Hi Max,

Is the WAKE button being held while bqStudio is being initialized? Can you please send a picture of the EVM so we can look at the jumper configuration?

Hi Max,

When bqStudio does not auto-detect the device, can you please share what is being seen in the image below?

EV2300 and EV2400 should be able to communicate in this situation.
