Multiple TF-Luna lidar sensors over i2c question

I have a TF-Luna lidar working over i2c (RNGFND1_ADDR=16 (I2c_slave_addr 0x10 default)) on my copter and I want to put 2 more TF-Lunas.
Question: Do I have to write first new I2c_slave_addresses into the TF-Luna lidars and assign the corresponding decimal for every RNGFNDX_ADDR?

yes you need to change i2c address of each tfluna sensor as default address in decimal is 16 i.e 0x10
