we were working on integrating arduino nano ble 33 with the 3 sensors, bme680, max30102, max30205.
when using arduino uno it is working well with the two sensors(max30102, max30205) in I2C and bme in SPI, it is working perfectly fine but when shifting to the arduino nano 33 ble sense, (nordic processor) some issues are observed but still the problem exists.
- both the sensors are not working simultaeneously. when i scanned the addresses, i am getting two address but not constant, one of the sensor address is disappearing and appearing, its not constant.
- when i have used three sensors in i2c interface mode, 3 sensors are not getting detected.
There is no problem with the sensors seperately i checked, working fine. but integration is not working in nano 33, same code is working in arduino uno.
using at 400khz, without pullup resistors.
why the sensors are not completely connected ? is there anything other than wire library i should use for nano 33 as it is nordic chip. Can you help in solving this issue.
