I wanted to connect two BME280 to my Arduino. Unfortunately I cant activate 0x77 and therefore both BMEs send data to 0x76.
Please help.
Hi, Tim
Refer to the BME280 data sheet “5.2 I2C Interface”.
“Connecting SDO to GND results in slave address 1110110 (0x76); connection it to VDDIO results in slave address 1110111 (0x77), …”
You need to connect one SDO pin to GND and the other SDO pin to VDDIO.
