H hung Active Member Licensed User Longtime User Sep 19, 2014 #3 In the walkie talkie example I use the internet ip (get from icanhazip.com) to make Connect Wifi but "trying to connect" then failed to connect. Do I need to use another connection method? the following is the ConnectWifi that I passed internet ip Code: Public Sub ConnectWifi(Ip As String) socket1.Initialize("socket1") socket1.Connect(Ip, port, 30000) WifiStatus = "Trying to connect..." UpdateUI End Sub Upvote 0

S sorex Expert Licensed User Longtime User Sep 19, 2014 #4 It should work but you need to apply some networking rules. 1. is a firewall blocking the request to port 30000 2. is there a forward rule in the firewall to your device for port 30000 On 3G networks there is probably nothing in between, unless your carrier is blocking none standard ports for security reasons. I only have 1 phone so I can't test it for you. Upvote 0

nwhitfield Active Member Licensed User Longtime User Sep 20, 2014 #5 If you want to avoid firewall issues, which can be a pain in the neck when on mobile devices, then the way round it is to have each device talking to the server, probably using port 80, rather than talking directly to each other. There's a small performance penalty, but it's not very high - you can still get pretty much real time communication. Upvote 0

KMatle Expert Licensed User Longtime User Sep 20, 2014 #6 I have a MySql-Database on a server. With httputils2 you can send the text, sender, receiver etc. to a php script which inserts it to the db. With f.e. a timer or on demand you can get those messages (Select message from xxxx where receiver = 'me'). So you never need to care about firewalls, ip addresses, etc. Upvote 0
