Sensors connected via the Grove I2C connector (D18/D17) were not detected because the firmware scanned the OLED I2C bus (Wire, D14/D15) by default. Adding ENV_PIN_SDA/SCL flags directs EnvironmentSensorManager to use Wire1, matching the physical Grove connector pinout. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

WioTrackerL1_companion_radio_bleenvironmentProblem
Sensors (e.g. BME280) connected to the Grove I2C port (Wire1: D18/D17) were
not detected because
EnvironmentSensorManagerdefaults to scanning the OLEDI2C bus (Wire: D14/D15) when
ENV_PIN_SDA/ENV_PIN_SCLare not defined.Fix
Added the two build flags so that
EnvironmentSensorManageruses Wire1 forsensor probing, matching the physical Grove connector pinout. The OLED display
on Wire is unaffected.
