Ultrasonic sensor

[niagFT]

Hi,

I have a question regarding how you get measurements from the URM04 sensors.

If I understand your code here correctly, then first you trigger a distance measurement from all 4 of them and then you send the command to get the result from all the sensors without reading the data from the bus in-between. I would expect something like:

• Ask data from sensor #0
• Read data from sensor #0
• Ask data from sensor Ultrasonic sensor #1
• Read data from sensor Ultrasonic sensor #1

etc.

How does your approach work?
