Arduino MKR1010 as USB host connects URG-04LX-UG01 with OTG cable. If you want more details ，the paper can provide help. this repository is base on https://github.com/gdsports/USB_Host_Library_SAMD . what I do is add a line in Usb.cpp ,because Arduino MKR was missing packet when Hokuyo URG-04LX-UG01 was sending.

urgacm can receive complete packet form URG-04LX-UG01,but it sends a charater form buf every time until the number of packet equal 64. urgacmAP1 sends whole buf to PC. the urgacmb20220421_servertext_DEMO.mp4 is recorded by urgacmb20220421_servertext program and UrgLidarTester.

UrgLidarTester is coded by jingyu Lin ，the professor of Guangdong University of Technology .

Pay attention to，it is a client in urgacm but server in urgacmAP and urgacmAP1.

The +5V pin of Arduino MKR 1010 should connect +5 sourse , and the GND pin connect GND. Just do this and you should premise the voltage of +5V pin is 5V at least when MKR is connecting URG-04LX-UG01,otherwise it can't connect WiFi or receive data of URG.

Upload example to MKR.If MKR is USBhost,you should click Reset button twice then the yellow LED of MKR flashes . In this time ,you can upload code when set correct port.

Set correct WiFi ssid and pass ,sure ,server need net port.
