Bolt connecting problem

I have problem in connecting Bolt.

Instead of welcome screen above screen is visible on mobile when I open NetPlug App

  1. I suggest you try the Method 2 of the setup given in the workshop.

  2. If the problem persists then let me know if IPAddress/settings page opens up.

I changed the BS.txt file as follows:
bolt_name:BOLT9171823
bolt_hostname:BOLT9171823
bolt_AP_name:BOLT9171823
bolt_AP_pswd:bolt1234
default_file:index.htm
download_file:wificon
ssid:Harsh-Net
pswd:prashant66

With NetPlug it gives following error:
" There seems to be an error with bolt. The start up files selected by you was not found. Please upload/select another file"
Kindly advice.
do I have to load SD card with any other file?
on SD card there is only one file ie. BS.txt.
