How CJP Protesters Stayed Connected Without the Internet? Here Is The Tech Behind It
According to reports, some of the CJP protestors were found using an app that allows them to send and receive messages without the internet.
New Delhi: Is it possible to send messages when internet is down? The Delhi Police is probing into the fact whether the protesters in Connaught Place, Jantar Mantar and other areas in Delhi have resorted to using messaging apps which are not connected to the internet. The protesters, who have been joining the Cockroach Janata Party (CJP) protest, were reportedly using certain applications to bypass internet connectivity and mobile network ban.
What is this app?
Some of the CJP protesters turned out to be using an application that lets them communicate with each other without the Internet, as per reports. According to reports, the Delhi Police has found a suspicious app being used by protestors.
According to reports, a BLE communication tool, which does not require an internet connection was used during the protest. But Delhi Police has not released the name of that particular App, which does not need a cell phone network, WiFi or mobile data.
These applications establish a local network by using Bluetooth. The local network can transmit messages even when there is no 4G, 5G and Wi-Fi coverage.
Can a person send messages even when the internet is down
Police believe that mobile internet has been blocked in parts of Delhi, while protesters are using Bluetooth-based communication apps to communicate with one another, says a report.
Police have not identified whether such apps were used, but the police have highlighted a technology they did not know much about. The applications enable smartphones to exchange messages without using mobile data, WiFi or cellular networks.
How do these apps work without a network?
Apps such as WhatsApp, Signal and Telegram work via mobile data or Wi-Fi, while apps that are not connected to the internet use Bluetooth Low Energy (BLE). It's a wireless technology that is embedded in nearly every smart phone today. There are lots of these applications, both locally accessible and widely available ones.
BitChat is one of the popular offline messaging apps launched by Jack Dorsey in July 2025. This app is downloaded more than a million times from the Google Play Store and enables users to send and receive messages using Bluetooth without the need for an account, phone number or central server. Android has other similar offline messaging apps, too.
