Description

I was unable to make a INA219 environment sensor working on the Lilygo T3S3 E-Paper, always got the message "Environment No measurement" on the display. Sensor is connected to the Qwiic connector on the PCB (RC43 / RC44 / GND / 3.3V).

Base on knowing that this works OLED T3S3 I did some research. If you add the two lines below to https://github.com/meshtastic/firmware/blob/master/variants/tlora_t3s3_epaper/variant.h and build Meshtastic, the environment measurements start to work: #define I2C_SDA1 43 #define I2C_SCL1 44

Not committing cause I don't have a GPS module to test the impact. In the same file the definition of the GPS pins might be conflicting: #define GPS_RX_PIN 44 #define GPS_TX_PIN 43
