BMP280 on I2C bus not working. Address conflict with BME280 on the same address by using both sensors at the same time.

Solution for this problem:

  1. Use only one sensor at the same time
  2. Change the BMP280 address from 0x76 to 0x77. It is possible to set the new address with a solder jumper. Details see hare:

Attention: The most modues have a fix wire jumper to GND. Before you make a solder jumper please cut the GND wire connection. After them you can use the solder jumper. Otherwise you make a short cut between GND and Vin.
