Hi,   
Prob to connect with UDP method :   
Android 7.0 
Windows 7 64bit 
Mock location is active for GPSBridge in developpement setting 
DCS OB 2.5.4 
No prob with my firewall, have open UDP 8080 port on my router 
Connection method : wifi     
DCS_NMEA.lua   
UDP Part 1   
	 my_init = socket.protect(function()
	host2, port2 = "192.168.1.11", 8080 --4353 -- replace IP with android device ip 
	udp = socket.try(socket.udp())	
end)
my_init()	   
UDP Part 2   
 my_send = socket.protect(function()
	local json = string.format("$%s*%x\r\n$%s*%x\r\n", GGA,csGGA,RMC,csRMC)
	socket.try(udp:sendto(json, host2, port2))
	end)
my_send()   
UDP Part 3   
 my_close = socket.protect(function()
	socket.try(udp:close())
end)
my_close()     
Export.lua (at the bottom)   
 userprofile = os.getenv ("userprofile"):gsub("\\","/")
dofile(userprofile .. "/Saved Games/DCS/Scripts/DCS_NMEA.lua")     
GPSBridge setting   
Protocol : UDP 
TCP/UDP port : 8080 
TCP adress : will attempt to connect to       
Thank's again for your help.
