I2C communication with nrf5340 custom board

[Vivek]

We are using nrf5340-dk to communicate with nrf5340 custom board and trying to search for the other sensors' addresses. There is secure mode and unsecure mode CPU. Which mode to try on? We could not detect the sensors I2C addresses.

Hello Vivek,

that doesn’t matter. You can use the I2C interface both as a secure and non-secure peripheral, as shown here.

Markus
