If the return value is “ 0 ”, it means the transfer was successful. “ 1 ” indicates that the data is too long to fit in the transfer buffer. The return value of the Wire.endTransmission() function can be useful, for example, when debugging. these values can be: If the parameter is false , Wire.endTransmission() sends a restart message after the transmission, so the I2C bus remains busy. This allows the current master device to send additional messages and prevents another master from taking over the I2C bus. If the parameter is true , Wire.endTransmission() sends a stop message after the transmission, releasing the I2C bus.
