Hello everybody I am trying to operate a pressure sensor (abp2 from Honeywell) behind an I2C multiplexer (TCA9548). The pressure sensor connected directly on I2C interface work great. I also also try another model of sensor (SHT31 temperature sensor) behind the multiplexer and work fine too. But i…

Yes, but I just found the problem... With all my apologies it's a simple problem of pull up resistor .. i remove it before because SHT sensor work without it even on multiplexer channels BUT ABP2 sensor work without resistor on the arduino i2C line, but NOT on TCA channel ! Have a nice day, and t…

What if you enable all channels at the same time? If you don't get data then something is wrong with your hardware. Please provide a circuit diagram.
