** Good day I have an error when sending data from the laser rangefinder I tried to use the library Adafruit_VL53L0X.h but it seems that the library SIM800l and Adafruit_VL53L0X.h conflicts because of this I connected the sensor without the library but still comes out error 702 but if you remove the laser rangefinder everything works with dht11.
if you know how to solve the problem please help **
