2 barometers (one bmp280 internal fc matek F405 CTR, one external DPS310), certainly conflict i2c adress (0x76/0x77), how to solve simply ?

[esorven]

Hello,
I wanted to upgrade my quad (F405 CTR Matek) with a new gps (m10125+barometer+magnetometer) with better barometer (dsp310) on my quad.
On inav 7, i took off the old gps (+magnometer) and put the new gps (+magnometer+barometer dps310):
=> magnometer ok but barometer unavailable. If i disconnect the gps, i have baro ok (the bmp280 of the fc).
I think of a conflicting i2c adress. (the two barometer havec the same adress 0x76 or 0x77 ?)

How can i solve this simply ?

• I thought of flashing F405 OSD which have a emulated i2c bus (tx3 rx3) and put the gps (sda scl) on it =, will it work, same speed i2c ?
• Is there a simple method to change i2c adress of internal baro (shorting sdo to ground for example), i'm scared of short circuit ?
• How can i remove or cut a trace simply to disable internal baro (i will using external one) ?

If somebody have a solution please ?
Thanks.
