iOS Question [Solved] B4iBuilder connection from iPhone problem

[Okan Özcan]

Hello,
Following the post from here https://www.b4x.com/android/forum/threads/b4i-bridge-problem.90515/#post-576728

After uninstalling it from the phone, I am unable to re-install B4iBridge to my phone. I am using a local mac builder. I can connect to mac server from my PC while iPhone's Safari fails to connect.

Mac, pc and phone all are in the same local wifi. I have re-created all certificates, provisions etc. to make sure all of them are proper. Building the B4i Bridge App from the IDE works fine. I can see the install app button when I connect from pc.

I was able to install B4iBridge last week with the same setup. I honestly don't know what changed.

Here is B4iBuilder's output:

When you say "iPhone's Safari fails to connect.", do you mean Safari just times out - "Safari could not open page........ " ?

I don't have the exact translation but it basically says "Safari could not open the page because server stopped responding.".

Appears to be a Network-related issue.

Try:

http://192.168.1.32:51041/test

from your phone.

If you don't get a response, try PINGing your MAC's IP address from your phone (you can download a free PINGer App from the store). Also make sure that your phone is connected to your local wifi and not the cellular network. You can check the IP address of your phone in Settings to be sure.

If all fails, try this:

I cannot connect to http://192.168.1.32:51041/test from phone either. I cannot ping to pc or mac from phone. I turned off cellular as you suggested and phone seems to have local ip, 192.168.1.20. I also tried https://www.b4x.com/android/forum/threads/b4i-bridge-problem.90515/#post-572216 but it still doesn't work.

I also downloaded the server example for B4j, and ran it in both mac and pc. While both of them connect to each other, phone still fails.

Trying a different approach, iPhone can connect to the ftp server running on my pc.

I guess something is wrong with my phone's configuration.

Yeah... looks like you have a LAN issue with your phone: Can you connect to the hosted builder:

http://63.135.170.51:51041/test

 

[Okan Özcan]

Yes I can connect to the hosted builder.

Things are getting a bit strange here

After a bit of research online, I found that turning wifi on/off on mac could solve this. It indeed helped. Trouble is B4iBuildServer reports a very strange IP (169.254.151.235). I could not compile b4ibridge using this IP so I entered 192.168.1.32 under IDE settings which worked.

I can now install B4iBridge and it shows designer preview. However it does not install and launch the app I am trying to debug. When I go to Safari on phone (to 169.254.151.235), I can install the app just like installing B4iBridge. I can debug the app in IDE using this method.

Also if I leave B4iBridge open long enough, it displays a message saying "Cannot connect: 192.168.1.32"

IP address that is displayed in the bridge depends on the settings of the wifi router in your home or office. If one and the same phone connect to a computer in the office or home will be used different IP.

You will need to force the builder to use the correct ip address. Otherwise the SSL key will not work.

See the multiple ip section: https://www.b4x.com/android/forum/threads/local-mac-builder-installation.46402/#content

I have fixed the problem by entering the IP manually as you guys said, reseting my modem and phone's network settings several times.
