Not able to setup the bolt cloud on my iphone

The bolt cloud is showing offline. Not getting how to make it online.

you have to connect to a hotspot device whose frequency band must be less than 2.5ghz. Even i had the same issue then it was solved by doing this.

Download the bolt app from playstore and the open it and add new device…Then connect a valid Wifi to the device that has high speed internet connection then proceed to complete the setup of the module.
Thank u!!

i’m getting a caution on my mobile screen that my phone has 5GHz and i need to connect it to 2.5, but i dont know how to do it?
