Then you can try VS code as developer studio is going to be end of life

I can provide teamviewer log id and pw to access the same PC that i trying to install.

You can have a look on this one:

Which ubuntu version are you using?
Are you using vmplayer?

Btw, your developer studio should be ok to compile the app.
You don’t really need to connect the module, you can ssh to module or scp the .update file to module for installation.

13

It is Ubuntu 18.04.3 LTS and not using VMplayer. it is installed in the laptop separate partition. It seems that need to reinstall ubuntu?

14

you can try, but I don’t see problem on ubuntu 18

15

hi, again the module is connecting to linux machine

it is pinging but not able to login with ssh root@192.168.2.2

as you said "did you shutdown the firewall of module by
iptables -I INPUT -j ACCEPT"

i cannot login to the module, how can i shutdown the firewall. i can shutdown PC firmware

16

Why you can connect before but now cannot?

17

I dont know actually, suddenly connected before and i did shutdown the firewall.

18

Then i don’t know about your pc either, you need to figure out what you had done before.
Definitely this is a pc instability issue
