BQ27510-G3: BQ27510 and EV2300 learning, I2C problems

Part Number: BQ27510-G3
Other Parts Discussed in Thread: BQ27510, BQSTUDIO

Hey everyone,

I'm working on a project which utilizes the BQ27510 gas gauge to monitor the battery charge. I'm trying to do a learning cycle with my battery on a prototype board, however, I'm having problems interfacing my EV2300 debugger with the gas gauge over I2C. I've hooked up an oscilloscope to the SDA and SCL lines to see what's going on there and it seems that the signal is the same on both lines, which shouldn't happen. There is no short and I've tried it with two different boards of mine with the same result. Despite this, communication with I2C over the uC is working okay so I'm a bit baffled.

The EV2300 interface board is recognized in Battery Management Studio, but because of my problem above I can't connect to the gas gauge. Does anyone have an idea what I might done wrong? Btw is it possible to do a learning cycle without an evaluation module (e.g. BQ27500EVM) when the schematic are basically the same? I've also ordered an EVM but delivery time is like 5 weeks or so...

Let me know if you need any further information, I'm happy to clarify. Thanks so much in advance!

Cheers!
