hi!!!
actually i wanted to change my wifi connected to the module ,when i tried disconnecting it asked for update but how will i update when i do not have the previous wifi connection?
@vidhayini.srikakula connect your wifi module to wifi connection you want by following the process which you have followed earlier.and then you can update the version of module.
you need not to disconnect anything,just make the connections once again.hope it helps.
please ask if help is needed,someone on forum will surely help

Hii @vidhayini.srikakula , using your Bolt App in the smartphone try to add the same device again and then connect to wifi which you want to use.
Hope it works.
