For still unknown reasons BNO055 and ICM20948 (and may probably others) have I2C-Scan issues when starting up or resetting. Without this fix, I2C-Scan has a random chance of not finding those IMUs. It either fails to find them or deadlocks the ESP. Example error: [INFO ] [SlimeVR] SlimeVR v0.2.3 starting up... [INFO ] [Configuration] Found up-to-date configuration v1 [DEBUG] [Configuration] Found sensor calibration for ICM20948 at index 0 [INFO ] [Configuration] Loaded configuration [ERR] I2C: Can't find I2C device on provided addresses, scanning for all I2C devices and returning [DBG] I2C (@ D2(4) : D1(5)): I2C device found at address 0x28 ! [ERROR] [ErroneousSensor:0] IMU of type BNO055 failed to initialize [INFO ] [BNO055Sensor:1] Connected to BNO055 at address 0x28
