flyingbepi commented on issue #1697: NRF52 Thingy:52 board does not report sensors on I2C bus #1 URL: https://github.com/apache/mynewt-core/issues/1697#issuecomment-474357622 The devices connected on the "second" IC2 bus are not powered on by default. So, the user needs to turn the Thingy:52 VDD power rail to enable I2C Sensors (Pressure, Humidity,..). This can be done this way: ``#define VDD_PWR_CTRL_GPIO_PIN 30`` ``....`` ``/ / Turn on Sensors Power Rail (VDD)`` ``hal_gpio_init_out(VDD_PWR_CTRL_GPIO_PIN, 1);``
