What is the logic level for the module DA14531 ?
More specifically what is the voltage that the module detect for a 1 on the GPIO?
I'm asking this because I want to use an I2C isolator but this kind of device has a voltage reference (around 0.6V) on one side so it doesn't create an infinite loop
and I'm able send data but can't recieve, and looking at the osciloscope I found that a signal that is not completely driven to ground (an acknoledge bit send by the slave) is not recognize by the module, and I could not find anything in the datasheet.
I know is not my software since I can communicate with the I2C sensor if connected directly.
