BME680 sensor jumpers configuration

Hi,

I try to use the BME680 sensor module, but actualy it doesent work (The software used can work with another BME680 buid connected to FT232H module, D1 & D2 shorted))
As the jumpers configuration is not really clear, can someone help?

My Vcc is 5V, so my conf is:
JP1: Opened the 2 copers wires ans soldered 4.7K between left pad and middle pad , 4.7K between right pad and middle pad
JP2: no change (Allpads shorted)
JP3 no change (Shorted)
JP4 no change (Open)

anything wrong?

Thank You

Didier

Hello Didier,
It was unnecessary to solder said resistors to that jumper, as that jumper itself was conencted to pull-up resistors on those lines. Did you try using the sensor before soldering said resistors? If you have a multimeter, could you check that the SDA and SCL pins, SDA/SCL and 3V3 or SDA/SCL and GND pins aren’t shorted?
Also, could you run a simple i2c scanner sketch to see if the BME sensor is available at the expected address of 0x76? Which Arduino Library are you using to communicate with it?

Hello josip,

thanks for answering,

there was no shortcut or defect, we made some more tests and the problem was in the software we made, trying to connect @0x77 , the modification for 0x76 was not in the compiled version… :sweat_smile:

Thanks :slight_smile:
