NMEA is the abbreviation of National Marine Electronics Association (National Maritime Electronics Association. The Association is a private institution dedicated to research on marine electronic devices and has developed NMEA standards for communication interfaces and protocols between GPS (GPS) electronic devices. NMEA-0183 protocol is currently the most widely

To share with you, but also for the future will not forget.NMEA protocol in general, relatively simple, is a relatively mature weather protocol.There are several main parameters and their formats: Wind speed and wind direction; Air temperature; Soil te

NMEA is a set of standard information that defines the output of the receiver. There are several different formats, each of which is an independent ASCII format that separates data streams. The data stream length ranges from 30 to characters, the output is usually selected at intervals per second. The most commonly used format is "GGA". It contains the positioning time, latitude, longitude, height, number of satellites used for positioning, and other

With the development of the routing industry, wireless technology has become its development direction. Here we mainly explain the differences and connections between wireless routers, wireless APs and wireless bridges, I hope to have a deeper understanding of wireless devic

　　Wireless AP: AP for access point abbreviation, generally translated as "Wireless Access Node", which is mainly to provide wireless workstations to the wired LAN and wireless workstations from the wired LAN access to the wireless workstation in the access points covered by

Use of ruijie in Wireless AP (Wireless Router ruijie wireless Internet access cannot authenticate AP) [tested: win7, xp, ubuntu 12.04 LTS are OK]Many campus networks or enterprise networks require ruijie verification.

When implementing wireless functionality in an existing wired network, you can use the wireless router as a wireless AP (wireless switch) and set the steps as follows: 1, a single connection and login to the wireless router, the wireles
